81097979 ÷ 987 
We're looking to find how many times 987 goes into 81097979.

Let's proceed to step 1:
987 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 987

Moving on to step 2:
987 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 987

Advancing to step 3:
If we divide 810 by 987, we get 0 and a remainder of 810.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 810, we end up with 810.
Fetch the next digit (9) from the dividend, attach it to 810 and continue: 8109 / 987

Let's proceed to step 4:
If we divide 8109 by 987, we get 8 and a remainder of 213.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7896 from 8109 leaves us with 213.
Take the next digit (7) from the dividend and append it to 213, then repeat: 2137 / 987

Going ahead to step 5:
If we divide 2137 by 987, we get 2 and a remainder of 163.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
The remainder is 163 after subtracting 1974 from 2137.
Fetch the next digit (9) from the dividend, attach it to 163 and continue: 1639 / 987

Let's proceed to step 6:
987 goes into 1639 1 times with a remainder of 652.
The next digit of our result is 1. 
Result so far: 821.0
If we subtract 987 from 1639, we get 652.
Bring next digit (7) of the dividend behind the 652 and repeat the process: 6527 / 987

Advancing to step 7:
When dividing 6527 by 987, we get 6 with a remainder of 605.
Use 6 as the next digit of our solution. 
Result so far: 8216.0
The remainder is 605 after subtracting 5922 from 6527.
Append the next digit (9) from the dividend to 605 and continue with: 6059 / 987

On to step 8:
If we divide 6059 by 987, we get 6 and a remainder of 137.
The next digit of our result is 6. 
Result so far: 82166.0
Deduct 5922 from 6059 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
The number 987 fits into 1370 1 times, leaving a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 82166.1
Subtract 987 from 1370 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Step 10:
If we divide 3830 by 987, we get 3 and a remainder of 869.
The number 3 becomes the next digit in our result. 
Result so far: 82166.13
If we take 2961 away from 3830, we end up with 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

Going ahead to step 11:
8690 divided by 987 is 8 with a remainder of 794.
Put 8 as the next digit of the answer. 
Result so far: 82166.138
Subtracting 7896 from 8690 leaves us with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Step 12:
987 can be fit into 7940 8 times, resulting in a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 82166.1388
Deduct 7896 from 7940 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 82166.1388 with a remaining 0.00044.
