111840 ÷ 45 
We want to divide 111840 by 45.

Going ahead to step 1:
45 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 45

Moving on to step 2:
45 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 45

Going ahead to step 3:
If we divide 111 by 45, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 90 from 111, we get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 45

On to step 4:
If we divide 218 by 45, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 38 after subtracting 180 from 218.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 45

On to step 5:
45 goes into 384 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 248.0
If we take 360 away from 384, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 45

Going ahead to step 6:
45 can be fit into 240 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2485.0
If we subtract 225 from 240, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 45 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 2485.3
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 2485.33
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 2485.33 with a remaining 0.015.
