We're dividing 110139 by 51 
Let's see how many times 51 fits into 110139.

Moving on to step 1:
51 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 51

Going ahead to step 2:
The number 51 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 51

On to step 3:
The number 51 fits into 110 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 102 from 110 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 51

Let's proceed to step 4:
81 divided by 51 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 51 from 81 to get 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 51

Going ahead to step 5:
303 divided by 51 is 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
If we subtract 255 from 303, we get 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 51

On to step 6:
When dividing 489 by 51, we get 9 with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 2159.0
If we take 459 away from 489, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
51 goes into 300 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 2159.5
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
51 goes into 450 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 2159.58
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2159.588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 2159.588 and a remainder of 0.0012.
