We're dividing 78217344 by 88 
We want to figure out the number of times 78217344 can be divided by 88.

Advancing to step 1:
7 divided by 88 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 88

Going ahead to step 2:
When dividing 78 by 88, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 88

Step 3:
88 can be fit into 782 8 times, resulting in a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 704 from 782, we get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 88

On to step 4:
The number 88 fits into 781 8 times, leaving a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we take 704 away from 781, we end up with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 88

On to step 5:
The number 88 fits into 777 8 times, leaving a remainder of 73.
Put 8 as the next digit of the answer. 
Result so far: 888.0
If we subtract 704 from 777, we get 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 88

On to step 6:
If we divide 733 by 88, we get 8 and a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 8888.0
Subtracting 704 from 733 leaves us with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 88

Going ahead to step 7:
The number 88 fits into 294 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 88883.0
If we take 264 away from 294, we end up with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 88

Going ahead to step 8:
The number 88 fits into 304 3 times, leaving a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 888833.0
If we subtract 264 from 304, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 88 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 888833.4
Subtracting 352 from 400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
When dividing 480 by 88, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 888833.45
Subtract 440 from 480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 88, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 888833.454
Deduct 352 from 400 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
If we divide 480 by 88, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 888833.4545
The remainder is 40 after subtracting 440 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
88 can be fit into 400 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 888833.45454
The remainder is 48 after subtracting 352 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
88 goes into 480 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 888833.454545
Deduct 440 from 480 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
88 can be fit into 400 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 888833.4545454
The remainder is 48 after subtracting 352 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
480 divided by 88 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 888833.45454545
Subtracting 440 from 480 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 888833.45454545 with a remaining 4e-08.
