We're dividing 99179854 by 864 
We want to figure out the number of times 99179854 can be divided by 864.

Step 1:
864 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 864

Advancing to step 2:
If we divide 99 by 864, we get 0 and a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 864

Advancing to step 3:
864 goes into 991 1 times with a remainder of 127.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 864 away from 991, we end up with 127.
Take the next digit (7) from the dividend and append it to 127, then repeat: 1277 / 864

Advancing to step 4:
864 can be fit into 1277 1 times, resulting in a remainder of 413.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 864 from 1277, we get 413.
Append the next digit (9) from the dividend to 413 and continue with: 4139 / 864

Advancing to step 5:
When dividing 4139 by 864, we get 4 with a remainder of 683.
The next digit of our result is 4. 
Result so far: 114.0
The remainder is 683 after subtracting 3456 from 4139.
Append the next digit (8) from the dividend to 683 and continue with: 6838 / 864

On to step 6:
If we divide 6838 by 864, we get 7 and a remainder of 790.
Use 7 as the next digit of our solution. 
Result so far: 1147.0
Deduct 6048 from 6838 and we're left with 790.
Append the next digit (5) from the dividend to 790 and continue with: 7905 / 864

Let's proceed to step 7:
When dividing 7905 by 864, we get 9 with a remainder of 129.
The number 9 becomes the next digit in our result. 
Result so far: 11479.0
Subtracting 7776 from 7905 leaves us with 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 864

Advancing to step 8:
When dividing 1294 by 864, we get 1 with a remainder of 430.
Record the quotient 1 as the next digit in the result. 
Result so far: 114791.0
Subtracting 864 from 1294 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 9:
If we divide 4300 by 864, we get 4 and a remainder of 844.
Write down 4 as next digit of the result. 
Result so far: 114791.4
If we subtract 3456 from 4300, we get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Step 10:
The number 864 fits into 8440 9 times, leaving a remainder of 664.
The number 9 becomes the next digit in our result. 
Result so far: 114791.49
If we subtract 7776 from 8440, we get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Going ahead to step 11:
864 can be fit into 6640 7 times, resulting in a remainder of 592.
The number 7 becomes the next digit in our result. 
Result so far: 114791.497
Subtracting 6048 from 6640 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 12:
864 can be fit into 5920 6 times, resulting in a remainder of 736.
Record the quotient 6 as the next digit in the result. 
Result so far: 114791.4976
Subtract 5184 from 5920 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.

Moving on to step 13:
864 goes into 7360 8 times with a remainder of 448.
The next digit of our result is 8. 
Result so far: 114791.49768
The remainder is 448 after subtracting 6912 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 14:
If we divide 4480 by 864, we get 5 and a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 114791.497685
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 15:
864 can be fit into 1600 1 times, resulting in a remainder of 736.
Use 1 as the next digit of our solution. 
Result so far: 114791.4976851
If we subtract 864 from 1600, we 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 16:
864 goes into 7360 8 times with a remainder of 448.
The next digit of our result is 8. 
Result so far: 114791.49768518
Subtracting 6912 from 7360 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

After the division, we end up with 114791.49768518 and a remainder of 4.48e-07.
