q = 10 // 3
mod = 10 % 3
print[q, mod]
# 3 1

The built-in function divmod[] is useful when you want both the quotient and remainder.

• Built-in Functions - divmod[] — Python 3.7.4 documentation

divmod[a, b] returns a tuple [a // b, a % b].

You can unpack and assign to each variable.

• Unpack a tuple and list in Python

q, mod = divmod[10, 3]
print[q, mod]
# 3 1

Of course, you can receive it as a tuple.

answer = divmod[10, 3]
print[answer]
print[answer[0], answer[1]]
# [3, 1]
# 3 1

Input:
n = 10
m = 3
Output:
Quotient:  3
Remainder 1

Input
n = 99
m = 5
Output:
Quotient:  19
Remainder 4

Quotient:  3
Remainder 1
Quotient:  19
Remainder 4

Quotient:  3
Remainder 1
Quotient:  19
Remainder 4

How could I go about finding the division remainder of a number in Python?

For example:
If the number is 26 and divided number is 7, then the division remainder is 5.
[since 7+7+7=21 and 26-21=5.]

you are looking for the modulo operator:

a % b

for example:

>>> 26 % 7
5

Of course, maybe they wanted you to implement it yourself, which wouldn't be too difficult either.

The remainder of a division can be discovered using the operator %:

>>> 26%7
5

In case you need both the quotient and the modulo, there's the builtin divmod function:

>>> seconds= 137
>>> minutes, seconds= divmod[seconds, 60]

26 % 7 [you will get remainder]

26 / 7 [you will get divisor, can be float value]

26 // 7 [you will get divisor, only integer value]

If you want to get quotient and remainder in one line of code [more general usecase], use:

quotient, remainder = divmod[dividend, divisor]
#or
divmod[26, 7]

From Python 3.7, there is a new math.remainder[] function:

from math import remainder
print[remainder[26,7]]

Output:

-2.0  # not 5

Note, as above, it's not the same as %.

Quoting the documentation:

math.remainder[x, y]

Return the IEEE 754-style remainder of x with respect to y. For finite x and finite nonzero y, this is the difference x - n*y, where n is the closest integer to the exact value of the quotient x / y. If x / y is exactly halfway between two consecutive integers, the nearest even integer is used for n. The remainder r = remainder[x, y] thus always satisfies abs[r]
