Fetch the next digit (5) from the dividend, attach it to 177 and continue: 1775 / 987

Step 5:
If we divide 1775 by 987, we get 1 and a remainder of 788.
Use 1 as the next digit of our solution. 
Result so far: 81.0
The remainder is 788 after subtracting 987 from 1775.
Fetch the next digit (5) from the dividend, attach it to 788 and continue: 7885 / 987

Let's proceed to step 6:
987 can be fit into 7885 7 times, resulting in a remainder of 976.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
Subtract 6909 from 7885 to get 976.
Grab the next digit (0) from the dividend, add it to 976, then carry on: 9760 / 987

On to step 7:
987 can be fit into 9760 9 times, resulting in a remainder of 877.
The number 9 becomes the next digit in our result. 
Result so far: 8179.0
Subtract 8883 from 9760 to get 877.
Append the next digit (6) from the dividend to 877 and continue with: 8776 / 987

Advancing to step 8:
When dividing 8776 by 987, we get 8 with a remainder of 880.
Write down 8 as next digit of the result. 
Result so far: 81798.0
Subtract 7896 from 8776 to get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Moving on to step 9:
The number 987 fits into 8800 8 times, leaving a remainder of 904.
Write down 8 as next digit of the result. 
Result so far: 81798.8
Deduct 7896 from 8800 and we're left with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Going ahead to step 10:
9040 divided by 987 is 9 with a remainder of 157.
Use 9 as the next digit of our solution. 
Result so far: 81798.89
If we subtract 8883 from 9040, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 11:
987 can be fit into 1570 1 times, resulting in a remainder of 583.
The next digit of our result is 1. 
Result so far: 81798.891
If we subtract 987 from 1570, we get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Step 12:
If we divide 5830 by 987, we get 5 and a remainder of 895.
Record the quotient 5 as the next digit in the result. 
Result so far: 81798.8915
If we subtract 4935 from 5830, we get 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

Advancing to step 13:
987 can be fit into 8950 9 times, resulting in a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 81798.89159
If we subtract 8883 from 8950, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 14:
670 divided by 987 is 0 with a remainder of 670.
Use 0 as the next digit of our solution. 
Result so far: 81798.89159
If we take 0 away from 670, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 15:
When dividing 6700 by 987, we get 6 with a remainder of 778.
Put 6 as the next digit of the answer. 
Result so far: 81798.8915906
The remainder is 778 after subtracting 5922 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

On to step 16:
987 goes into 7780 7 times with a remainder of 871.
Record the quotient 7 as the next digit in the result. 
Result so far: 81798.89159067
If we take 6909 away from 7780, we end up with 871.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8710, and continue the process.

The quotient of the division is 81798.89159067, and the remainder is 8.71e-07.
