Let's divide 45150 by 20
We're looking to find how many times 20 goes into 45150.

Step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 20

Advancing to step 2:
20 goes into 45 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 45 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 20

Step 3:
If we divide 51 by 20, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 40 from 51 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 20

Moving on to step 4:
20 can be fit into 115 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
Subtracting 100 from 115 leaves us with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 20

Moving on to step 5:
If we divide 150 by 20, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 2257.0
Deduct 140 from 150 and we're left 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 6:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2257.5
Deduct 100 from 100 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.

On to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2257.5
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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2257.5
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.

Our division results in 2257.5 with a remaining 0.0.
