We're dividing 77292680 by 864 
We want to figure out the number of times 77292680 can be divided by 864.

Advancing to step 1:
If we divide 7 by 864, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 864

Moving on to step 2:
The number 864 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 864

Advancing to step 3:
The number 864 fits into 772 0 times, leaving a remainder of 772.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 772, we get 772.
Grab the next digit (9) from the dividend, add it to 772, then carry on: 7729 / 864

Moving on to step 4:
The number 864 fits into 7729 8 times, leaving a remainder of 817.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 817 after subtracting 6912 from 7729.
Take the next digit (2) from the dividend and append it to 817, then repeat: 8172 / 864

Step 5:
8172 divided by 864 is 9 with a remainder of 396.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
The remainder is 396 after subtracting 7776 from 8172.
Take the next digit (6) from the dividend and append it to 396, then repeat: 3966 / 864

Let's proceed to step 6:
864 can be fit into 3966 4 times, resulting in a remainder of 510.
The next digit of our result is 4. 
Result so far: 894.0
If we take 3456 away from 3966, we end up with 510.
Fetch the next digit (8) from the dividend, attach it to 510 and continue: 5108 / 864

Step 7:
5108 divided by 864 is 5 with a remainder of 788.
Use 5 as the next digit of our solution. 
Result so far: 8945.0
If we subtract 4320 from 5108, we get 788.
Grab the next digit (0) from the dividend, add it to 788, then carry on: 7880 / 864

Advancing to step 8:
The number 864 fits into 7880 9 times, leaving a remainder of 104.
Use 9 as the next digit of our solution. 
Result so far: 89459.0
If we subtract 7776 from 7880, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 9:
864 goes into 1040 1 times with a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 89459.1
Subtracting 864 from 1040 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 10:
864 goes into 1760 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 89459.12
The remainder is 32 after subtracting 1728 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
320 divided by 864 is 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 89459.12
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
864 can be fit into 3200 3 times, resulting in a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 89459.1203
Subtracting 2592 from 3200 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 13:
When dividing 6080 by 864, we get 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 89459.12037
The remainder is 32 after subtracting 6048 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
The number 864 fits into 320 0 times, leaving a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 89459.12037
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
If we divide 3200 by 864, we get 3 and a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 89459.1203703
If we subtract 2592 from 3200, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 16:
6080 divided by 864 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 89459.12037037
If we take 6048 away from 6080, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 89459.12037037, and the remainder is 3.2e-08.
