We look at the division of 99021387 by 627 
Let's see how many times 627 fits into 99021387.

Step 1:
627 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 627

Let's proceed to step 2:
When dividing 99 by 627, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 627

Let's proceed to step 3:
The number 627 fits into 990 1 times, leaving a remainder of 363.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 627 from 990 and we're left with 363.
Append the next digit (2) from the dividend to 363 and continue with: 3632 / 627

Going ahead to step 4:
3632 divided by 627 is 5 with a remainder of 497.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 497 after subtracting 3135 from 3632.
Take the next digit (1) from the dividend and append it to 497, then repeat: 4971 / 627

Going ahead to step 5:
If we divide 4971 by 627, we get 7 and a remainder of 582.
Write down 7 as next digit of the result. 
Result so far: 157.0
If we take 4389 away from 4971, we end up with 582.
Include the next digit (3) from the dividend after 582, then repeat: 5823 / 627

Step 6:
When dividing 5823 by 627, we get 9 with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 1579.0
If we take 5643 away from 5823, we end up with 180.
Append the next digit (8) from the dividend to 180 and continue with: 1808 / 627

On to step 7:
If we divide 1808 by 627, we get 2 and a remainder of 554.
Use 2 as the next digit of our solution. 
Result so far: 15792.0
Subtracting 1254 from 1808 leaves us with 554.
Include the next digit (7) from the dividend after 554, then repeat: 5547 / 627

On to step 8:
When dividing 5547 by 627, we get 8 with a remainder of 531.
The next digit of our result is 8. 
Result so far: 157928.0
If we take 5016 away from 5547, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 9:
If we divide 5310 by 627, we get 8 and a remainder of 294.
Record the quotient 8 as the next digit in the result. 
Result so far: 157928.8
If we subtract 5016 from 5310, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 10:
627 goes into 2940 4 times with a remainder of 432.
Use 4 as the next digit of our solution. 
Result so far: 157928.84
Subtracting 2508 from 2940 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 11:
627 can be fit into 4320 6 times, resulting in a remainder of 558.
The number 6 becomes the next digit in our result. 
Result so far: 157928.846
The remainder is 558 after subtracting 3762 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 12:
The number 627 fits into 5580 8 times, leaving a remainder of 564.
Record the quotient 8 as the next digit in the result. 
Result so far: 157928.8468
Subtract 5016 from 5580 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 13:
627 goes into 5640 8 times with a remainder of 624.
Write down 8 as next digit of the result. 
Result so far: 157928.84688
Deduct 5016 from 5640 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Our division results in 157928.84688 with a remaining 0.000624.
