We're dividing 78885721 by 108 
We want to figure out the number of times 78885721 can be divided by 108.

Step 1:
When dividing 7 by 108, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 108

Let's proceed to step 2:
78 divided by 108 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 108

On to step 3:
The number 108 fits into 788 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 756 from 788 and we're left with 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 108

Let's proceed to step 4:
The number 108 fits into 328 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 324 from 328 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 108

Moving on to step 5:
108 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 730.0
If we subtract 0 from 45, we get 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 108

Let's proceed to step 6:
If we divide 457 by 108, we get 4 and a remainder of 25.
The next digit of our result is 4. 
Result so far: 7304.0
The remainder is 25 after subtracting 432 from 457.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 108

Step 7:
The number 108 fits into 252 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 73042.0
Subtracting 216 from 252 leaves us with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 108

Going ahead to step 8:
The number 108 fits into 361 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 730423.0
Deduct 324 from 361 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
108 can be fit into 370 3 times, resulting in a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 730423.3
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
When dividing 460 by 108, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 730423.34
Subtract 432 from 460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
If we divide 280 by 108, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 730423.342
If we take 216 away from 280, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
When dividing 640 by 108, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 730423.3425
If we subtract 540 from 640, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
1000 divided by 108 is 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 730423.34259
The remainder is 28 after subtracting 972 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
108 can be fit into 280 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 730423.342592
Subtracting 216 from 280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
The number 108 fits into 640 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 730423.3425925
If we take 540 away from 640, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
1000 divided by 108 is 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 730423.34259259
Deduct 972 from 1000 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 730423.34259259 with a remaining 2.8e-08.
