837531 divided by 20 
We're looking to find how many times 20 goes into 837531.

On to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
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

Step 2:
20 goes into 83 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 80 from 83 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 20

Going ahead to step 3:
If we divide 37 by 20, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 41.0
Deduct 20 from 37 and we're left with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 20

Step 4:
20 goes into 175 8 times with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 418.0
Subtract 160 from 175 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 20

Let's proceed to step 5:
If we divide 153 by 20, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 4187.0
If we take 140 away from 153, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 20

Let's proceed to step 6:
If we divide 131 by 20, we get 6 and a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 41876.0
If we take 120 away from 131, we end up 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:
When dividing 110 by 20, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 41876.5
If we take 100 away from 110, we end up with 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 41876.55
If we subtract 100 from 100, 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 quotient of the division is 41876.55, and the remainder is 0.0.
