Let's divide 731885 by 21
Our goal is to divide 731885 by 21.

Let's proceed to step 1:
7 divided by 21 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 21

On to step 2:
When dividing 73 by 21, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 63 from 73 and we're left with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 21

On to step 3:
101 divided by 21 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 84 from 101 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 21

Going ahead to step 4:
If we divide 178 by 21, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 348.0
Deduct 168 from 178 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 21

On to step 5:
108 divided by 21 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 3485.0
If we subtract 105 from 108, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 21

On to step 6:
35 divided by 21 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 34851.0
If we take 21 away from 35, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
21 goes into 140 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 34851.6
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 34851.66
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 34851.66, and the remainder is 0.014.
