512752 divided by 45 
We're looking to find how many times 45 goes into 512752.

Step 1:
5 divided by 45 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 45

Advancing to step 2:
When dividing 51 by 45, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 6 after subtracting 45 from 51.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 45

On to step 3:
The number 45 fits into 62 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 45 away from 62, we end up with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 45

Step 4:
177 divided by 45 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we subtract 135 from 177, we get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 45

Going ahead to step 5:
45 goes into 425 9 times with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 1139.0
Subtracting 405 from 425 leaves us with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 45

Moving on to step 6:
The number 45 fits into 202 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 11394.0
Subtracting 180 from 202 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
45 goes into 220 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 11394.4
Deduct 180 from 220 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 11394.48
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 11394.488
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 11394.488 with a remaining 0.004.
