452569 ÷ 45 
We want to figure out the number of times 452569 can be divided by 45.

Going ahead to step 1:
If we divide 4 by 45, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 45

On to step 2:
45 can be fit into 45 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 45, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 45

Advancing to step 3:
The number 45 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 45

Going ahead to step 4:
If we divide 25 by 45, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 25, we get 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 45

On to step 5:
When dividing 256 by 45, we get 5 with a remainder of 31.
The next digit of our result is 5. 
Result so far: 1005.0
If we subtract 225 from 256, we get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 45

Step 6:
When dividing 319 by 45, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 10057.0
Subtracting 315 from 319 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 45, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10057.0
Deduct 0 from 40 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.

Moving on to step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 10057.08
If we take 360 away from 400, we end up 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:
400 divided by 45 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 10057.088
The remainder is 40 after subtracting 360 from 400.
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 10057.088 with a remaining 0.004.
