86879 divided by 88 
We want to figure out the number of times 86879 can be divided by 88.

Advancing to step 1:
88 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 88

Advancing to step 2:
When dividing 86 by 88, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 88

Going ahead to step 3:
868 divided by 88 is 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 792 from 868 leaves us with 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 88

On to step 4:
If we divide 767 by 88, we get 8 and a remainder of 63.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 704 from 767 leaves us with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 88

Let's proceed to step 5:
88 can be fit into 639 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 987.0
The remainder is 23 after subtracting 616 from 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 6:
If we divide 230 by 88, we get 2 and a remainder of 54.
The next digit of our result is 2. 
Result so far: 987.2
If we subtract 176 from 230, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
540 divided by 88 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 987.26
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
When dividing 120 by 88, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 987.261
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.

On to step 9:
If we divide 320 by 88, we get 3 and a remainder of 56.
The next digit of our result is 3. 
Result so far: 987.2613
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
88 can be fit into 560 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 987.26136
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
320 divided by 88 is 3 with a remainder of 56.
The next digit of our result is 3. 
Result so far: 987.261363
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
88 can be fit into 560 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 987.2613636
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
88 goes into 320 3 times with a remainder of 56.
The next digit of our result is 3. 
Result so far: 987.26136363
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 987.26136363, with a leftover of 5.6e-08.
