Let's divide 628403 by 99
We're looking to find how many times 99 goes into 628403.

Moving on to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 99

Advancing to step 2:
If we divide 62 by 99, we get 0 and a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 99

Moving on to step 3:
If we divide 628 by 99, we get 6 and a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 594 from 628 leaves us with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 99

Going ahead to step 4:
If we divide 344 by 99, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 63.0
Subtracting 297 from 344 leaves us with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 99

Step 5:
When dividing 470 by 99, we get 4 with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 634.0
Deduct 396 from 470 and we're left with 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 99

On to step 6:
The number 99 fits into 743 7 times, leaving a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 6347.0
Deduct 693 from 743 and we're left 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.

Moving on to step 7:
99 goes into 500 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6347.5
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
99 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6347.5
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
99 goes into 500 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6347.505
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
The number 99 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6347.505
Subtracting 0 from 50 leaves us 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.

Going ahead to step 11:
If we divide 500 by 99, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6347.50505
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
99 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 6347.50505
Subtracting 0 from 50 leaves us 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.

Moving on to step 13:
If we divide 500 by 99, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6347.5050505
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
If we divide 50 by 99, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 6347.5050505
If we take 0 away from 50, 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.

The final outcome is 6347.5050505, with a leftover of 5e-08.
