We look at the division of 86246248 by 864 
We want to divide 86246248 by 864.

Going ahead to step 1:
The number 864 fits into 8 0 times, leaving 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.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 864

Going ahead to step 2:
If we divide 86 by 864, we get 0 and a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (2) of the dividend behind the 86 and repeat the process: 862 / 864

Let's proceed to step 3:
If we divide 862 by 864, we get 0 and a remainder of 862.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 862 to get 862.
Take the next digit (4) from the dividend and append it to 862, then repeat: 8624 / 864

Step 4:
864 can be fit into 8624 9 times, resulting in a remainder of 848.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7776 from 8624 leaves us with 848.
Take the next digit (6) from the dividend and append it to 848, then repeat: 8486 / 864

Let's proceed to step 5:
8486 divided by 864 is 9 with a remainder of 710.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 7776 from 8486 leaves us with 710.
Append the next digit (2) from the dividend to 710 and continue with: 7102 / 864

On to step 6:
864 can be fit into 7102 8 times, resulting in a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 998.0
If we take 6912 away from 7102, we end up with 190.
Bring next digit (4) of the dividend behind the 190 and repeat the process: 1904 / 864

On to step 7:
If we divide 1904 by 864, we get 2 and a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 9982.0
Subtract 1728 from 1904 to get 176.
Append the next digit (8) from the dividend to 176 and continue with: 1768 / 864

On to step 8:
864 can be fit into 1768 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 99822.0
If we subtract 1728 from 1768, we 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.

Moving on to step 9:
864 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 99822.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
The number 864 fits into 4000 4 times, leaving a remainder of 544.
Put 4 as the next digit of the answer. 
Result so far: 99822.04
If we take 3456 away from 4000, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 11:
When dividing 5440 by 864, we get 6 with a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 99822.046
The remainder is 256 after subtracting 5184 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 12:
If we divide 2560 by 864, we get 2 and a remainder of 832.
Use 2 as the next digit of our solution. 
Result so far: 99822.0462
If we subtract 1728 from 2560, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 13:
When dividing 8320 by 864, we get 9 with a remainder of 544.
Write down 9 as next digit of the result. 
Result so far: 99822.04629
Subtract 7776 from 8320 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 14:
864 can be fit into 5440 6 times, resulting in a remainder of 256.
The next digit of our result is 6. 
Result so far: 99822.046296
Subtract 5184 from 5440 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 15:
If we divide 2560 by 864, we get 2 and a remainder of 832.
Put 2 as the next digit of the answer. 
Result so far: 99822.0462962
If we subtract 1728 from 2560, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

On to step 16:
The number 864 fits into 8320 9 times, leaving a remainder of 544.
Put 9 as the next digit of the answer. 
Result so far: 99822.04629629
Subtract 7776 from 8320 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The quotient of the division is 99822.04629629, and the remainder is 5.44e-07.
