Let's divide 748757 by 20
We want to figure out the number of times 748757 can be divided by 20.

Advancing to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 20

Step 2:
If we divide 74 by 20, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 60 from 74 to get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 20

Going ahead to step 3:
When dividing 148 by 20, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 140 from 148 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Going ahead to step 4:
20 goes into 87 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 374.0
If we subtract 80 from 87, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 20

Step 5:
If we divide 75 by 20, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3743.0
Subtract 60 from 75 to get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 20

Advancing to step 6:
157 divided by 20 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 37437.0
Subtracting 140 from 157 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
170 divided by 20 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 37437.8
If we take 160 away from 170, 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.

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: 37437.85
Subtract 100 from 100 to 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.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37437.85
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.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37437.85
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 37437.85 with a remainder of 0.0.
