We look at the division of 907566 by 20 
We want to figure out the number of times 907566 can be divided by 20.

Let's proceed to step 1:
20 goes into 9 0 times 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.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 20

Moving on to step 2:
The number 20 fits into 90 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 80 from 90 to get 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 20

Advancing to step 3:
If we divide 107 by 20, we get 5 and a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 100 from 107 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 20

Going ahead to step 4:
20 goes into 75 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 453.0
The remainder is 15 after subtracting 60 from 75.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 20

Let's proceed to step 5:
156 divided by 20 is 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 4537.0
If we subtract 140 from 156, we get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 20

Step 6:
20 goes into 166 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 45378.0
Subtract 160 from 166 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 20 fits into 60 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 45378.3
Deduct 60 from 60 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.
Write down 0 as next digit of the result. 
Result so far: 45378.3
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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45378.3
Subtract 0 from 0 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.

Our division results in 45378.3 with a remaining 0.0.
