We look at the division of 837371 by 20 
Our goal is to divide 837371 by 20.

On to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 20

Going ahead to step 2:
20 goes into 83 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 80 from 83, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 20

Moving on to step 3:
20 goes into 37 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 20 from 37 leaves us with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 20

On to step 4:
The number 20 fits into 173 8 times, leaving a remainder of 13.
The next digit of our result is 8. 
Result so far: 418.0
Subtract 160 from 173 to get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 20

Going ahead to step 5:
If we divide 137 by 20, we get 6 and a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 4186.0
If we take 120 away from 137, we end up with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 20

Going ahead to step 6:
When dividing 171 by 20, we get 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 41868.0
Subtracting 160 from 171 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 41868.5
If we subtract 100 from 110, 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.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 41868.55
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.

After the division, we end up with 41868.55 and a remainder of 0.0.
