72748396 divided by 864 
We want to figure out the number of times 72748396 can be divided by 864.

Moving on to step 1:
When dividing 7 by 864, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 864

Going ahead to step 2:
The number 864 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 864

Let's proceed to step 3:
727 divided by 864 is 0 with a remainder of 727.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 727 and we're left with 727.
Take the next digit (4) from the dividend and append it to 727, then repeat: 7274 / 864

Step 4:
864 goes into 7274 8 times with a remainder of 362.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6912 away from 7274, we end up with 362.
Take the next digit (8) from the dividend and append it to 362, then repeat: 3628 / 864

Moving on to step 5:
864 can be fit into 3628 4 times, resulting in a remainder of 172.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 3456 from 3628, we get 172.
Grab the next digit (3) from the dividend, add it to 172, then carry on: 1723 / 864

Advancing to step 6:
When dividing 1723 by 864, we get 1 with a remainder of 859.
The next digit of our result is 1. 
Result so far: 841.0
Subtract 864 from 1723 to get 859.
Take the next digit (9) from the dividend and append it to 859, then repeat: 8599 / 864

Let's proceed to step 7:
When dividing 8599 by 864, we get 9 with a remainder of 823.
Record the quotient 9 as the next digit in the result. 
Result so far: 8419.0
If we subtract 7776 from 8599, we get 823.
Include the next digit (6) from the dividend after 823, then repeat: 8236 / 864

Step 8:
If we divide 8236 by 864, we get 9 and a remainder of 460.
Put 9 as the next digit of the answer. 
Result so far: 84199.0
Subtract 7776 from 8236 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 9:
The number 864 fits into 4600 5 times, leaving a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 84199.5
Deduct 4320 from 4600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
When dividing 2800 by 864, we get 3 with a remainder of 208.
Use 3 as the next digit of our solution. 
Result so far: 84199.53
Subtract 2592 from 2800 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
If we divide 2080 by 864, we get 2 and a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 84199.532
Subtracting 1728 from 2080 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 12:
The number 864 fits into 3520 4 times, leaving a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 84199.5324
The remainder is 64 after subtracting 3456 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
864 can be fit into 640 0 times, resulting in a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 84199.5324
The remainder is 640 after subtracting 0 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
When dividing 6400 by 864, we get 7 with a remainder of 352.
Put 7 as the next digit of the answer. 
Result so far: 84199.532407
Subtract 6048 from 6400 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 15:
864 goes into 3520 4 times with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 84199.5324074
If we subtract 3456 from 3520, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
If we divide 640 by 864, we get 0 and a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 84199.5324074
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 84199.5324074 with a remaining 6.4e-07.
