861385 divided by 88 
Our goal is to divide 861385 by 88.

Step 1:
When dividing 8 by 88, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 88

Advancing to step 2:
88 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 88

On to step 3:
88 goes into 861 9 times with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 792 away from 861, we end up with 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 88

Going ahead to step 4:
693 divided by 88 is 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 616 from 693 and we're left with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 88

Going ahead to step 5:
When dividing 778 by 88, we get 8 with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 978.0
Deduct 704 from 778 and we're left with 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 88

Let's proceed to step 6:
The number 88 fits into 745 8 times, leaving a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 9788.0
If we take 704 away from 745, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
If we divide 410 by 88, we get 4 and a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 9788.4
Subtracting 352 from 410 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
The number 88 fits into 580 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 9788.46
Subtracting 528 from 580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
88 goes into 520 5 times with a remainder of 80.
The next digit of our result is 5. 
Result so far: 9788.465
Subtract 440 from 520 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
800 divided by 88 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9788.4659
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
88 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 9788.4659
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 88, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9788.465909
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
88 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 9788.465909
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
When dividing 800 by 88, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 9788.46590909
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 9788.46590909, with a leftover of 8e-09.
