We look at the division of 113912 by 45 
We want to divide 113912 by 45.

Advancing to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 45

Going ahead to step 2:
When dividing 11 by 45, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 45

Going ahead to step 3:
113 divided by 45 is 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 90 from 113 leaves us with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 45

Step 4:
When dividing 239 by 45, we get 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 225 from 239 to get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 45

Let's proceed to step 5:
45 goes into 141 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 253.0
The remainder is 6 after subtracting 135 from 141.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 45

Step 6:
62 divided by 45 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 2531.0
The remainder is 17 after subtracting 45 from 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
170 divided by 45 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 2531.3
If we subtract 135 from 170, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
350 divided by 45 is 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 2531.37
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 2531.377
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 2531.377 with a remaining 0.0035.
