78666105 ÷ 88 
We want to divide 78666105 by 88.

Advancing to step 1:
88 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 88

Moving on to step 2:
88 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 88

On to step 3:
88 goes into 786 8 times with a remainder of 82.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 704 from 786 leaves us with 82.
Grab the next digit (6) from the dividend, add it to 82, then carry on: 826 / 88

Moving on to step 4:
88 goes into 826 9 times with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Subtract 792 from 826 to get 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 88

Let's proceed to step 5:
The number 88 fits into 346 3 times, leaving a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 893.0
The remainder is 82 after subtracting 264 from 346.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 88

Advancing to step 6:
If we divide 821 by 88, we get 9 and a remainder of 29.
The next digit of our result is 9. 
Result so far: 8939.0
Deduct 792 from 821 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 88

Advancing to step 7:
88 can be fit into 290 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 89393.0
Subtracting 264 from 290 leaves us with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 88

Going ahead to step 8:
88 can be fit into 265 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 893933.0
Subtracting 264 from 265 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 88, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 893933.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 88, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 893933.01
Subtract 88 from 100 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
88 goes into 120 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 893933.011
If we subtract 88 from 120, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 893933.011, and the remainder is 0.0032.
