We look at the division of 99778486 by 628 
We're looking to find how many times 628 goes into 99778486.

Advancing to step 1:
The number 628 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 628

Step 2:
When dividing 99 by 628, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 628

Let's proceed to step 3:
If we divide 997 by 628, we get 1 and a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 369 after subtracting 628 from 997.
Bring next digit (7) of the dividend behind the 369 and repeat the process: 3697 / 628

Moving on to step 4:
When dividing 3697 by 628, we get 5 with a remainder of 557.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 557 after subtracting 3140 from 3697.
Take the next digit (8) from the dividend and append it to 557, then repeat: 5578 / 628

Step 5:
The number 628 fits into 5578 8 times, leaving a remainder of 554.
The next digit of our result is 8. 
Result so far: 158.0
Subtract 5024 from 5578 to get 554.
Append the next digit (4) from the dividend to 554 and continue with: 5544 / 628

On to step 6:
628 goes into 5544 8 times with a remainder of 520.
Put 8 as the next digit of the answer. 
Result so far: 1588.0
The remainder is 520 after subtracting 5024 from 5544.
Bring next digit (8) of the dividend behind the 520 and repeat the process: 5208 / 628

Going ahead to step 7:
When dividing 5208 by 628, we get 8 with a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 15888.0
Subtracting 5024 from 5208 leaves us with 184.
Append the next digit (6) from the dividend to 184 and continue with: 1846 / 628

Going ahead to step 8:
628 can be fit into 1846 2 times, resulting in a remainder of 590.
The next digit of our result is 2. 
Result so far: 158882.0
Subtracting 1256 from 1846 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 9:
The number 628 fits into 5900 9 times, leaving a remainder of 248.
The number 9 becomes the next digit in our result. 
Result so far: 158882.9
Deduct 5652 from 5900 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
When dividing 2480 by 628, we get 3 with a remainder of 596.
Write down 3 as next digit of the result. 
Result so far: 158882.93
The remainder is 596 after subtracting 1884 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 11:
5960 divided by 628 is 9 with a remainder of 308.
Put 9 as the next digit of the answer. 
Result so far: 158882.939
Subtract 5652 from 5960 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 12:
If we divide 3080 by 628, we get 4 and a remainder of 568.
Put 4 as the next digit of the answer. 
Result so far: 158882.9394
Subtract 2512 from 3080 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 13:
628 goes into 5680 9 times with a remainder of 28.
The next digit of our result is 9. 
Result so far: 158882.93949
Deduct 5652 from 5680 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
280 divided by 628 is 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 158882.93949
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
If we divide 2800 by 628, we get 4 and a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 158882.9394904
Subtracting 2512 from 2800 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 16:
2880 divided by 628 is 4 with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 158882.93949044
If we subtract 2512 from 2880, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 158882.93949044, with a leftover of 3.68e-07.
