We look at the division of 55098575 by 429 
We want to divide 55098575 by 429.

On to step 1:
429 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 429

Let's proceed to step 2:
429 goes into 55 0 times with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 429

Step 3:
The number 429 fits into 550 1 times, leaving a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 121 after subtracting 429 from 550.
Append the next digit (9) from the dividend to 121 and continue with: 1219 / 429

Step 4:
If we divide 1219 by 429, we get 2 and a remainder of 361.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 858 away from 1219, we end up with 361.
Bring next digit (8) of the dividend behind the 361 and repeat the process: 3618 / 429

Going ahead to step 5:
429 goes into 3618 8 times with a remainder of 186.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 3432 from 3618 leaves us with 186.
Append the next digit (5) from the dividend to 186 and continue with: 1865 / 429

Moving on to step 6:
429 goes into 1865 4 times with a remainder of 149.
The number 4 becomes the next digit in our result. 
Result so far: 1284.0
The remainder is 149 after subtracting 1716 from 1865.
Bring next digit (7) of the dividend behind the 149 and repeat the process: 1497 / 429

Moving on to step 7:
1497 divided by 429 is 3 with a remainder of 210.
The number 3 becomes the next digit in our result. 
Result so far: 12843.0
Subtracting 1287 from 1497 leaves us with 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 429

Advancing to step 8:
429 can be fit into 2105 4 times, resulting in a remainder of 389.
Use 4 as the next digit of our solution. 
Result so far: 128434.0
Subtracting 1716 from 2105 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 9:
The number 429 fits into 3890 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 128434.9
If we take 3861 away from 3890, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
290 divided by 429 is 0 with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 128434.9
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 11:
429 can be fit into 2900 6 times, resulting in a remainder of 326.
Record the quotient 6 as the next digit in the result. 
Result so far: 128434.906
Subtracting 2574 from 2900 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 12:
429 goes into 3260 7 times with a remainder of 257.
The number 7 becomes the next digit in our result. 
Result so far: 128434.9067
If we subtract 3003 from 3260, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 13:
The number 429 fits into 2570 5 times, leaving a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 128434.90675
Deduct 2145 from 2570 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 14:
If we divide 4250 by 429, we get 9 and a remainder of 389.
Use 9 as the next digit of our solution. 
Result so far: 128434.906759
Subtracting 3861 from 4250 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 15:
The number 429 fits into 3890 9 times, leaving a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 128434.9067599
The remainder is 29 after subtracting 3861 from 3890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 128434.9067599, with a leftover of 2.9e-07.
