We're dividing 99016157 by 639 
We want to figure out the number of times 99016157 can be divided by 639.

Going ahead to step 1:
The number 639 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 639

Let's proceed to step 2:
If we divide 99 by 639, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 639

On to step 3:
639 can be fit into 990 1 times, resulting in a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 639 from 990 to get 351.
Bring next digit (1) of the dividend behind the 351 and repeat the process: 3511 / 639

Moving on to step 4:
639 can be fit into 3511 5 times, resulting in a remainder of 316.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 3195 from 3511 leaves us with 316.
Fetch the next digit (6) from the dividend, attach it to 316 and continue: 3166 / 639

Step 5:
639 goes into 3166 4 times with a remainder of 610.
The next digit of our result is 4. 
Result so far: 154.0
Subtract 2556 from 3166 to get 610.
Include the next digit (1) from the dividend after 610, then repeat: 6101 / 639

On to step 6:
When dividing 6101 by 639, we get 9 with a remainder of 350.
Use 9 as the next digit of our solution. 
Result so far: 1549.0
If we subtract 5751 from 6101, we get 350.
Fetch the next digit (5) from the dividend, attach it to 350 and continue: 3505 / 639

Advancing to step 7:
3505 divided by 639 is 5 with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 15495.0
Deduct 3195 from 3505 and we're left with 310.
Include the next digit (7) from the dividend after 310, then repeat: 3107 / 639

On to step 8:
The number 639 fits into 3107 4 times, leaving a remainder of 551.
The number 4 becomes the next digit in our result. 
Result so far: 154954.0
If we take 2556 away from 3107, we end up with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Going ahead to step 9:
639 can be fit into 5510 8 times, resulting in a remainder of 398.
Write down 8 as next digit of the result. 
Result so far: 154954.8
Deduct 5112 from 5510 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 10:
639 can be fit into 3980 6 times, resulting in a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 154954.86
Subtract 3834 from 3980 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 11:
When dividing 1460 by 639, we get 2 with a remainder of 182.
The number 2 becomes the next digit in our result. 
Result so far: 154954.862
Subtracting 1278 from 1460 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 12:
The number 639 fits into 1820 2 times, leaving a remainder of 542.
Put 2 as the next digit of the answer. 
Result so far: 154954.8622
The remainder is 542 after subtracting 1278 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

After the division, we end up with 154954.8622 and a remainder of 0.00542.
