We look at the division of 935121 by 20 
We want to divide 935121 by 20.

Step 1:
9 divided by 20 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 20

Advancing to step 2:
When dividing 93 by 20, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 80 from 93, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 20

Step 3:
The number 20 fits into 135 6 times, leaving a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 120 from 135, we get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 20

Advancing to step 4:
151 divided by 20 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 467.0
Subtracting 140 from 151 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 20

Advancing to step 5:
If we divide 112 by 20, we get 5 and a remainder of 12.
The next digit of our result is 5. 
Result so far: 4675.0
Deduct 100 from 112 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 20

On to step 6:
The number 20 fits into 121 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 46756.0
Subtracting 120 from 121 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 20 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 46756.0
If we take 0 away from 10, 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.

Going ahead to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 46756.05
If we take 100 away from 100, 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 46756.05
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.

Step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 46756.05
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.

The final result is 46756.05 with a remainder of 0.0.
