We look at the division of 115992 by 45 
We want to figure out the number of times 115992 can be divided by 45.

On to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 45

Going ahead to step 2:
11 divided by 45 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 45

Moving on to step 3:
115 divided by 45 is 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 90 from 115 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 45

Moving on to step 4:
The number 45 fits into 259 5 times, leaving a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 225 from 259 to get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 45

Step 5:
When dividing 349 by 45, we get 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 257.0
Subtract 315 from 349 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 45

On to step 6:
The number 45 fits into 342 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 2577.0
If we subtract 315 from 342, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
270 divided by 45 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2577.6
Subtracting 270 from 270 leaves us 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.

Going ahead to step 8:
45 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2577.6
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.

Moving on to step 9:
45 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: 2577.6
If we subtract 0 from 0, we 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.

The final result is 2577.6 with a remainder of 0.0.
