88 goes into 247 2 times with a remainder of 71.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 176 from 247 leaves us with 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 88

Going ahead to step 5:
714 divided by 88 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 1028.0
Subtracting 704 from 714 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 88

Moving on to step 6:
If we divide 102 by 88, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 10281.0
Subtract 88 from 102 to get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 88

Advancing to step 7:
When dividing 149 by 88, we get 1 with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 102811.0
The remainder is 61 after subtracting 88 from 149.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 88

Going ahead to step 8:
88 goes into 611 6 times with a remainder of 83.
Put 6 as the next digit of the answer. 
Result so far: 1028116.0
Subtracting 528 from 611 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 9:
When dividing 830 by 88, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 1028116.9
Subtract 792 from 830 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 88 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 1028116.94
Subtracting 352 from 380 leaves us 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.

Let's proceed to step 11:
If we divide 280 by 88, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 1028116.943
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
When dividing 160 by 88, we get 1 with a remainder of 72.
The next digit of our result is 1. 
Result so far: 1028116.9431
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
720 divided by 88 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 1028116.94318
If we subtract 704 from 720, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
88 goes into 160 1 times with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 1028116.943181
The remainder is 72 after subtracting 88 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 15:
If we divide 720 by 88, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1028116.9431818
Subtracting 704 from 720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
If we divide 160 by 88, we get 1 and a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 1028116.94318181
The remainder is 72 after subtracting 88 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 1028116.94318181 with a balance of 7.2e-08.
