80870940 ÷ 987 
Our goal is to divide 80870940 by 987.

Going ahead to step 1:
987 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 987

Moving on to step 2:
80 divided by 987 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 987

On to step 3:
If we divide 808 by 987, we get 0 and a remainder of 808.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 808 leaves us with 808.
Take the next digit (7) from the dividend and append it to 808, then repeat: 8087 / 987

Going ahead to step 4:
The number 987 fits into 8087 8 times, leaving a remainder of 191.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7896 away from 8087, we end up with 191.
Grab the next digit (0) from the dividend, add it to 191, then carry on: 1910 / 987

Advancing to step 5:
If we divide 1910 by 987, we get 1 and a remainder of 923.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtract 987 from 1910 to get 923.
Append the next digit (9) from the dividend to 923 and continue with: 9239 / 987

Advancing to step 6:
987 goes into 9239 9 times with a remainder of 356.
Use 9 as the next digit of our solution. 
Result so far: 819.0
The remainder is 356 after subtracting 8883 from 9239.
Take the next digit (4) from the dividend and append it to 356, then repeat: 3564 / 987

Step 7:
987 can be fit into 3564 3 times, resulting in a remainder of 603.
The number 3 becomes the next digit in our result. 
Result so far: 8193.0
Subtracting 2961 from 3564 leaves us with 603.
Fetch the next digit (0) from the dividend, attach it to 603 and continue: 6030 / 987

Going ahead to step 8:
If we divide 6030 by 987, we get 6 and a remainder of 108.
Put 6 as the next digit of the answer. 
Result so far: 81936.0
If we subtract 5922 from 6030, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 9:
The number 987 fits into 1080 1 times, leaving a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 81936.1
The remainder is 93 after subtracting 987 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 10:
930 divided by 987 is 0 with a remainder of 930.
Put 0 as the next digit of the answer. 
Result so far: 81936.1
Subtracting 0 from 930 leaves us with 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Moving on to step 11:
987 can be fit into 9300 9 times, resulting in a remainder of 417.
Record the quotient 9 as the next digit in the result. 
Result so far: 81936.109
The remainder is 417 after subtracting 8883 from 9300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Going ahead to step 12:
If we divide 4170 by 987, we get 4 and a remainder of 222.
The number 4 becomes the next digit in our result. 
Result so far: 81936.1094
If we take 3948 away from 4170, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 13:
987 goes into 2220 2 times with a remainder of 246.
Put 2 as the next digit of the answer. 
Result so far: 81936.10942
The remainder is 246 after subtracting 1974 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 14:
The number 987 fits into 2460 2 times, leaving a remainder of 486.
The number 2 becomes the next digit in our result. 
Result so far: 81936.109422
The remainder is 486 after subtracting 1974 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Our division results in 81936.109422 with a remaining 4.86e-05.
