We look at the division of 252319 by 45 
Our goal is to divide 252319 by 45.

Going ahead to step 1:
If we divide 2 by 45, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
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

Advancing to step 2:
If we divide 25 by 45, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 45

On to step 3:
45 goes into 252 5 times with a remainder of 27.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 225 from 252 leaves us with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 45

On to step 4:
273 divided by 45 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 270 from 273, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 45

Let's proceed to step 5:
If we divide 31 by 45, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 560.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 45

Step 6:
If we divide 319 by 45, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 5607.0
Deduct 315 from 319 and we're left 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.

Let's proceed to step 7:
When dividing 40 by 45, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5607.0
Subtracting 0 from 40 leaves us 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.

Let's proceed to 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: 5607.08
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.

On to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 5607.088
Subtracting 360 from 400 leaves us 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.

The final result is 5607.088 with a remainder of 0.004.
