We look at the division of 76907104 by 864 
We want to divide 76907104 by 864.

Advancing to step 1:
When dividing 7 by 864, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 864

Step 2:
The number 864 fits into 76 0 times, leaving a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Bring next digit (9) of the dividend behind the 76 and repeat the process: 769 / 864

Going ahead to step 3:
The number 864 fits into 769 0 times, leaving a remainder of 769.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 769 and we're left with 769.
Include the next digit (0) from the dividend after 769, then repeat: 7690 / 864

Moving on to step 4:
864 can be fit into 7690 8 times, resulting in a remainder of 778.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6912 from 7690 and we're left with 778.
Grab the next digit (7) from the dividend, add it to 778, then carry on: 7787 / 864

Advancing to step 5:
When dividing 7787 by 864, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we take 7776 away from 7787, we end up with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 864

Moving on to step 6:
If we divide 111 by 864, we get 0 and a remainder of 111.
The number 0 becomes the next digit in our result. 
Result so far: 890.0
If we subtract 0 from 111, we get 111.
Take the next digit (0) from the dividend and append it to 111, then repeat: 1110 / 864

Going ahead to step 7:
The number 864 fits into 1110 1 times, leaving a remainder of 246.
Use 1 as the next digit of our solution. 
Result so far: 8901.0
If we take 864 away from 1110, we end up with 246.
Include the next digit (4) from the dividend after 246, then repeat: 2464 / 864

Going ahead to step 8:
864 can be fit into 2464 2 times, resulting in a remainder of 736.
Use 2 as the next digit of our solution. 
Result so far: 89012.0
Subtract 1728 from 2464 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Advancing to step 9:
If we divide 7360 by 864, we get 8 and a remainder of 448.
The number 8 becomes the next digit in our result. 
Result so far: 89012.8
Subtract 6912 from 7360 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 10:
If we divide 4480 by 864, we get 5 and a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 89012.85
The remainder is 160 after subtracting 4320 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
The number 864 fits into 1600 1 times, leaving a remainder of 736.
Record the quotient 1 as the next digit in the result. 
Result so far: 89012.851
If we take 864 away from 1600, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

On to step 12:
7360 divided by 864 is 8 with a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 89012.8518
Subtract 6912 from 7360 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 13:
If we divide 4480 by 864, we get 5 and a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 89012.85185
The remainder is 160 after subtracting 4320 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
864 goes into 1600 1 times with a remainder of 736.
The number 1 becomes the next digit in our result. 
Result so far: 89012.851851
The remainder is 736 after subtracting 864 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 15:
The number 864 fits into 7360 8 times, leaving a remainder of 448.
Write down 8 as next digit of the result. 
Result so far: 89012.8518518
Subtract 6912 from 7360 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 16:
The number 864 fits into 4480 5 times, leaving a remainder of 160.
The next digit of our result is 5. 
Result so far: 89012.85185185
If we subtract 4320 from 4480, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 89012.85185185, and the remainder is 1.6e-07.
