We look at the division of 55173963 by 99 
We want to figure out the number of times 55173963 can be divided by 99.

Advancing to step 1:
99 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 subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 99

Advancing to step 2:
If we divide 55 by 99, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 99

Let's proceed to step 3:
When dividing 551 by 99, we get 5 with a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 56 after subtracting 495 from 551.
Append the next digit (7) from the dividend to 56 and continue with: 567 / 99

On to step 4:
567 divided by 99 is 5 with a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we subtract 495 from 567, we get 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 99

On to step 5:
When dividing 723 by 99, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 557.0
Subtracting 693 from 723 leaves us with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 99

Moving on to step 6:
The number 99 fits into 309 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 5573.0
Subtract 297 from 309 to get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 99

On to step 7:
The number 99 fits into 126 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 55731.0
The remainder is 27 after subtracting 99 from 126.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 99

Step 8:
When dividing 273 by 99, we get 2 with a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 557312.0
Deduct 198 from 273 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
When dividing 750 by 99, we get 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 557312.7
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
The number 99 fits into 570 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 557312.75
Subtracting 495 from 570 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
The number 99 fits into 750 7 times, leaving a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 557312.757
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
99 can be fit into 570 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 557312.7575
The remainder is 75 after subtracting 495 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
99 can be fit into 750 7 times, resulting in a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 557312.75757
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
When dividing 570 by 99, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 557312.757575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
The number 99 fits into 750 7 times, leaving a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 557312.7575757
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 16:
When dividing 570 by 99, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 557312.75757575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 557312.75757575, with a leftover of 7.5e-08.
