79243497 divided by 864 
We want to figure out the number of times 79243497 can be divided by 864.

Moving on to step 1:
7 divided by 864 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 864

On to step 2:
864 goes into 79 0 times with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 864

Moving on to step 3:
864 goes into 792 0 times with a remainder of 792.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 792 to get 792.
Grab the next digit (4) from the dividend, add it to 792, then carry on: 7924 / 864

Step 4:
If we divide 7924 by 864, we get 9 and a remainder of 148.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7776 from 7924, we get 148.
Include the next digit (3) from the dividend after 148, then repeat: 1483 / 864

Advancing to step 5:
864 can be fit into 1483 1 times, resulting in a remainder of 619.
Put 1 as the next digit of the answer. 
Result so far: 91.0
The remainder is 619 after subtracting 864 from 1483.
Fetch the next digit (4) from the dividend, attach it to 619 and continue: 6194 / 864

Moving on to step 6:
6194 divided by 864 is 7 with a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 917.0
Subtract 6048 from 6194 to get 146.
Append the next digit (9) from the dividend to 146 and continue with: 1469 / 864

On to step 7:
The number 864 fits into 1469 1 times, leaving a remainder of 605.
Write down 1 as next digit of the result. 
Result so far: 9171.0
Deduct 864 from 1469 and we're left with 605.
Include the next digit (7) from the dividend after 605, then repeat: 6057 / 864

Step 8:
6057 divided by 864 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 91717.0
Subtracting 6048 from 6057 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
When dividing 90 by 864, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 91717.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 864 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 91717.01
Subtracting 864 from 900 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
864 can be fit into 360 0 times, resulting in a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 91717.01
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 12:
When dividing 3600 by 864, we get 4 with a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 91717.0104
Subtracting 3456 from 3600 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
864 can be fit into 1440 1 times, resulting in a remainder of 576.
Record the quotient 1 as the next digit in the result. 
Result so far: 91717.01041
If we subtract 864 from 1440, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 14:
If we divide 5760 by 864, we get 6 and a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 91717.010416
If we take 5184 away from 5760, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 15:
When dividing 5760 by 864, we get 6 with a remainder of 576.
Write down 6 as next digit of the result. 
Result so far: 91717.0104166
If we take 5184 away from 5760, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Our division results in 91717.0104166 with a remaining 5.76e-06.
