We look at the division of 86408163 by 984 
We want to divide 86408163 by 984.

Step 1:
The number 984 fits into 8 0 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 984

On to step 2:
If we divide 86 by 984, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 984

Step 3:
984 goes into 864 0 times with a remainder of 864.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 864 leaves us with 864.
Include the next digit (0) from the dividend after 864, then repeat: 8640 / 984

Moving on to step 4:
984 goes into 8640 8 times with a remainder of 768.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 7872 from 8640 leaves us with 768.
Take the next digit (8) from the dividend and append it to 768, then repeat: 7688 / 984

Step 5:
The number 984 fits into 7688 7 times, leaving a remainder of 800.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtract 6888 from 7688 to get 800.
Grab the next digit (1) from the dividend, add it to 800, then carry on: 8001 / 984

Moving on to step 6:
984 can be fit into 8001 8 times, resulting in a remainder of 129.
Record the quotient 8 as the next digit in the result. 
Result so far: 878.0
If we subtract 7872 from 8001, we get 129.
Fetch the next digit (6) from the dividend, attach it to 129 and continue: 1296 / 984

Advancing to step 7:
984 can be fit into 1296 1 times, resulting in a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 8781.0
The remainder is 312 after subtracting 984 from 1296.
Take the next digit (3) from the dividend and append it to 312, then repeat: 3123 / 984

Going ahead to step 8:
984 goes into 3123 3 times with a remainder of 171.
Record the quotient 3 as the next digit in the result. 
Result so far: 87813.0
Subtracting 2952 from 3123 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
The number 984 fits into 1710 1 times, leaving a remainder of 726.
Write down 1 as next digit of the result. 
Result so far: 87813.1
Subtracting 984 from 1710 leaves us with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Moving on to step 10:
The number 984 fits into 7260 7 times, leaving a remainder of 372.
The number 7 becomes the next digit in our result. 
Result so far: 87813.17
Subtracting 6888 from 7260 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 11:
When dividing 3720 by 984, we get 3 with a remainder of 768.
The number 3 becomes the next digit in our result. 
Result so far: 87813.173
If we subtract 2952 from 3720, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Moving on to step 12:
If we divide 7680 by 984, we get 7 and a remainder of 792.
Use 7 as the next digit of our solution. 
Result so far: 87813.1737
Subtract 6888 from 7680 to get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Let's proceed to step 13:
984 can be fit into 7920 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 87813.17378
Subtracting 7872 from 7920 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
The number 984 fits into 480 0 times, leaving a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 87813.17378
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 15:
4800 divided by 984 is 4 with a remainder of 864.
Put 4 as the next digit of the answer. 
Result so far: 87813.1737804
Deduct 3936 from 4800 and we're left with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

On to step 16:
The number 984 fits into 8640 8 times, leaving a remainder of 768.
The next digit of our result is 8. 
Result so far: 87813.17378048
Deduct 7872 from 8640 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

The quotient of the division is 87813.17378048, and the remainder is 7.68e-07.
