We look at the division of 15617535 by 987 
Our goal is to divide 15617535 by 987.

Let's proceed to step 1:
When dividing 1 by 987, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 987

Step 2:
The number 987 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 987

Moving on to step 3:
When dividing 156 by 987, we get 0 with a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Fetch the next digit (1) from the dividend, attach it to 156 and continue: 1561 / 987

On to step 4:
1561 divided by 987 is 1 with a remainder of 574.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 987 away from 1561, we end up with 574.
Take the next digit (7) from the dividend and append it to 574, then repeat: 5747 / 987

Advancing to step 5:
5747 divided by 987 is 5 with a remainder of 812.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 4935 from 5747 leaves us with 812.
Append the next digit (5) from the dividend to 812 and continue with: 8125 / 987

Step 6:
If we divide 8125 by 987, we get 8 and a remainder of 229.
Put 8 as the next digit of the answer. 
Result so far: 158.0
If we take 7896 away from 8125, we end up with 229.
Bring next digit (3) of the dividend behind the 229 and repeat the process: 2293 / 987

On to step 7:
987 goes into 2293 2 times with a remainder of 319.
Use 2 as the next digit of our solution. 
Result so far: 1582.0
If we take 1974 away from 2293, we end up with 319.
Take the next digit (5) from the dividend and append it to 319, then repeat: 3195 / 987

On to step 8:
987 can be fit into 3195 3 times, resulting in a remainder of 234.
Record the quotient 3 as the next digit in the result. 
Result so far: 15823.0
Deduct 2961 from 3195 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
987 goes into 2340 2 times with a remainder of 366.
Write down 2 as next digit of the result. 
Result so far: 15823.2
Subtract 1974 from 2340 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 10:
If we divide 3660 by 987, we get 3 and a remainder of 699.
Use 3 as the next digit of our solution. 
Result so far: 15823.23
If we take 2961 away from 3660, we end up with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Step 11:
987 can be fit into 6990 7 times, resulting in a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 15823.237
If we subtract 6909 from 6990, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 12:
987 goes into 810 0 times with a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 15823.237
The remainder is 810 after subtracting 0 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 13:
8100 divided by 987 is 8 with a remainder of 204.
The next digit of our result is 8. 
Result so far: 15823.23708
Subtracting 7896 from 8100 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 14:
2040 divided by 987 is 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 15823.237082
If we subtract 1974 from 2040, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 15:
If we divide 660 by 987, we get 0 and a remainder of 660.
Put 0 as the next digit of the answer. 
Result so far: 15823.237082
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 16:
When dividing 6600 by 987, we get 6 with a remainder of 678.
Record the quotient 6 as the next digit in the result. 
Result so far: 15823.23708206
If we subtract 5922 from 6600, we get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

After the division, we end up with 15823.23708206 and a remainder of 6.78e-07.
