Let's divide 313163 by 20
We want to divide 313163 by 20.

Going ahead to step 1:
3 divided by 20 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

On to step 2:
20 goes into 31 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 20 from 31 leaves us with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 20

Advancing to step 3:
20 goes into 113 5 times with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 100 from 113 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 20

On to step 4:
131 divided by 20 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 156.0
If we take 120 away from 131, we end up with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 20

Moving on to step 5:
When dividing 116 by 20, we get 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 1565.0
If we subtract 100 from 116, we get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 20

Advancing to step 6:
163 divided by 20 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 15658.0
If we take 160 away from 163, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 15658.1
The remainder is 10 after subtracting 20 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15658.15
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15658.15
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15658.15
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15658.15 with a remainder of 0.0.
