86980378 divided by 87 
We want to divide 86980378 by 87.

Let's proceed to step 1:
When dividing 8 by 87, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 87

Going ahead to step 2:
86 divided by 87 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 87

On to step 3:
869 divided by 87 is 9 with a remainder of 86.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 783 from 869 to get 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 87

Advancing to step 4:
87 goes into 868 9 times with a remainder of 85.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 783 away from 868, we end up with 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 87

Advancing to step 5:
When dividing 850 by 87, we get 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 999.0
Deduct 783 from 850 and we're left with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 87

Going ahead to step 6:
If we divide 673 by 87, we get 7 and a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 9997.0
If we take 609 away from 673, we end up with 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 87

Step 7:
87 can be fit into 647 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 99977.0
If we take 609 away from 647, we end up with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 87

On to step 8:
388 divided by 87 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 999774.0
Subtract 348 from 388 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
87 goes into 400 4 times with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 999774.4
Deduct 348 from 400 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
If we divide 520 by 87, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 999774.45
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
When dividing 850 by 87, we get 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 999774.459
Subtracting 783 from 850 leaves us with 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 12:
87 goes into 670 7 times with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 999774.4597
If we take 609 away from 670, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
87 can be fit into 610 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 999774.45977
The remainder is 1 after subtracting 609 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 999774.45977 with a remainder of 1e-06.
