Let's divide 635280 by 20
We're looking to find how many times 20 goes into 635280.

On to step 1:
6 divided by 20 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Advancing to step 2:
63 divided by 20 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 60 away from 63, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 20

Step 3:
When dividing 35 by 20, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 20 from 35 leaves us with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 20

Step 4:
20 goes into 152 7 times with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtracting 140 from 152 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 20

Advancing to step 5:
The number 20 fits into 128 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3176.0
Deduct 120 from 128 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 20

Advancing to step 6:
When dividing 80 by 20, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 31764.0
Deduct 80 from 80 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.

Advancing to step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31764.0
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.

Moving on to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31764.0
If we take 0 away from 0, we end up 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 final outcome is 31764.0, with a leftover of 0.0.
