We look at the division of 99956129 by 54 
We want to divide 99956129 by 54.

Going ahead to step 1:
When dividing 9 by 54, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 54

On to step 2:
54 can be fit into 99 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 54 from 99 to get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 54

Let's proceed to step 3:
When dividing 459 by 54, we get 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 432 away from 459, we end up with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 54

Moving on to step 4:
54 can be fit into 275 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 185.0
If we take 270 away from 275, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 54

Let's proceed to step 5:
54 goes into 56 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1851.0
The remainder is 2 after subtracting 54 from 56.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 54

Advancing to step 6:
21 divided by 54 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 18510.0
If we take 0 away from 21, we end up with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 54

Step 7:
The number 54 fits into 212 3 times, leaving a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 185103.0
If we subtract 162 from 212, we get 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 54

Going ahead to step 8:
The number 54 fits into 509 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 1851039.0
If we take 486 away from 509, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
If we divide 230 by 54, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 1851039.4
Subtracting 216 from 230 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
The number 54 fits into 140 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1851039.42
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
When dividing 320 by 54, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 1851039.425
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
54 goes into 500 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 1851039.4259
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
The number 54 fits into 140 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1851039.42592
Subtract 108 from 140 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
If we divide 320 by 54, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1851039.425925
If we subtract 270 from 320, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 15:
54 goes into 500 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 1851039.4259259
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 16:
If we divide 140 by 54, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1851039.42592592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 1851039.42592592 and a remainder of 3.2e-08.
