Moving on to step 5:
987 can be fit into 9775 9 times, resulting in a remainder of 892.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
The remainder is 892 after subtracting 8883 from 9775.
Take the next digit (7) from the dividend and append it to 892, then repeat: 8927 / 987

Advancing to step 6:
987 goes into 8927 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 799.0
The remainder is 44 after subtracting 8883 from 8927.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 987

Advancing to step 7:
When dividing 445 by 987, we get 0 with a remainder of 445.
Put 0 as the next digit of the answer. 
Result so far: 7990.0
If we subtract 0 from 445, we get 445.
Append the next digit (8) from the dividend to 445 and continue with: 4458 / 987

Step 8:
If we divide 4458 by 987, we get 4 and a remainder of 510.
Write down 4 as next digit of the result. 
Result so far: 79904.0
If we subtract 3948 from 4458, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 9:
5100 divided by 987 is 5 with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 79904.5
Subtract 4935 from 5100 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
When dividing 1650 by 987, we get 1 with a remainder of 663.
The next digit of our result is 1. 
Result so far: 79904.51
Subtracting 987 from 1650 leaves us with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Let's proceed to step 11:
The number 987 fits into 6630 6 times, leaving a remainder of 708.
Write down 6 as next digit of the result. 
Result so far: 79904.516
Deduct 5922 from 6630 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

On to step 12:
987 can be fit into 7080 7 times, resulting in a remainder of 171.
The next digit of our result is 7. 
Result so far: 79904.5167
If we subtract 6909 from 7080, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 13:
When dividing 1710 by 987, we get 1 with a remainder of 723.
Record the quotient 1 as the next digit in the result. 
Result so far: 79904.51671
Subtract 987 from 1710 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 14:
The number 987 fits into 7230 7 times, leaving a remainder of 321.
The next digit of our result is 7. 
Result so far: 79904.516717
The remainder is 321 after subtracting 6909 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 15:
987 can be fit into 3210 3 times, resulting in a remainder of 249.
Write down 3 as next digit of the result. 
Result so far: 79904.5167173
The remainder is 249 after subtracting 2961 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 16:
The number 987 fits into 2490 2 times, leaving a remainder of 516.
Write down 2 as next digit of the result. 
Result so far: 79904.51671732
Subtracting 1974 from 2490 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

After the division, we end up with 79904.51671732 and a remainder of 5.16e-07.
