We're dividing 68709901 by 864 
Let's see how many times 864 fits into 68709901.

On to step 1:
864 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 864

On to step 2:
68 divided by 864 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 864

Step 3:
When dividing 687 by 864, we get 0 with a remainder of 687.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 687 leaves us with 687.
Append the next digit (0) from the dividend to 687 and continue with: 6870 / 864

Step 4:
The number 864 fits into 6870 7 times, leaving a remainder of 822.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 6048 from 6870 and we're left with 822.
Take the next digit (9) from the dividend and append it to 822, then repeat: 8229 / 864

Step 5:
When dividing 8229 by 864, we get 9 with a remainder of 453.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 7776 from 8229 leaves us with 453.
Fetch the next digit (9) from the dividend, attach it to 453 and continue: 4539 / 864

Going ahead to step 6:
If we divide 4539 by 864, we get 5 and a remainder of 219.
Write down 5 as next digit of the result. 
Result so far: 795.0
If we subtract 4320 from 4539, we get 219.
Include the next digit (0) from the dividend after 219, then repeat: 2190 / 864

On to step 7:
2190 divided by 864 is 2 with a remainder of 462.
Write down 2 as next digit of the result. 
Result so far: 7952.0
The remainder is 462 after subtracting 1728 from 2190.
Take the next digit (1) from the dividend and append it to 462, then repeat: 4621 / 864

Going ahead to step 8:
864 goes into 4621 5 times with a remainder of 301.
Record the quotient 5 as the next digit in the result. 
Result so far: 79525.0
The remainder is 301 after subtracting 4320 from 4621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 9:
The number 864 fits into 3010 3 times, leaving a remainder of 418.
The next digit of our result is 3. 
Result so far: 79525.3
If we take 2592 away from 3010, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 10:
The number 864 fits into 4180 4 times, leaving a remainder of 724.
The number 4 becomes the next digit in our result. 
Result so far: 79525.34
The remainder is 724 after subtracting 3456 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Step 11:
7240 divided by 864 is 8 with a remainder of 328.
Write down 8 as next digit of the result. 
Result so far: 79525.348
If we take 6912 away from 7240, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 12:
864 can be fit into 3280 3 times, resulting in a remainder of 688.
Put 3 as the next digit of the answer. 
Result so far: 79525.3483
If we take 2592 away from 3280, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Moving on to step 13:
The number 864 fits into 6880 7 times, leaving a remainder of 832.
The next digit of our result is 7. 
Result so far: 79525.34837
The remainder is 832 after subtracting 6048 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Step 14:
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: 79525.348379
Subtracting 7776 from 8320 leaves us 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.

Advancing to step 15:
864 goes into 5440 6 times with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 79525.3483796
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 16:
The number 864 fits into 2560 2 times, leaving a remainder of 832.
Use 2 as the next digit of our solution. 
Result so far: 79525.34837962
The remainder is 832 after subtracting 1728 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

After the division, we end up with 79525.34837962 and a remainder of 8.32e-07.
