171637 ÷ 20 
Our goal is to divide 171637 by 20.

Let's proceed to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 20

On to step 2:
20 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 20

On to step 3:
When dividing 171 by 20, we get 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 160 from 171, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 20

Advancing to step 4:
If we divide 116 by 20, we get 5 and a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 100 from 116 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 20

Advancing to step 5:
20 can be fit into 163 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 858.0
Subtracting 160 from 163 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 20

Advancing to step 6:
If we divide 37 by 20, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 8581.0
The remainder is 17 after subtracting 20 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
When dividing 170 by 20, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 8581.8
If we subtract 160 from 170, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8581.85
Subtracting 100 from 100 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.

Going ahead to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8581.85
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8581.85
Deduct 0 from 0 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.

The quotient of the division is 8581.85, and the remainder is 0.0.
