We divide 864531 by 88
Our goal is to divide 864531 by 88.

Advancing to step 1:
88 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 88

Let's proceed to step 2:
86 divided by 88 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 88

Moving on to step 3:
864 divided by 88 is 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 792 from 864 to get 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 88

Step 4:
The number 88 fits into 725 8 times, leaving a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtract 704 from 725 to get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 88

Going ahead to step 5:
The number 88 fits into 213 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 982.0
If we take 176 away from 213, we end up with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 88

Let's proceed to step 6:
If we divide 371 by 88, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 9824.0
Deduct 352 from 371 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 88 fits into 190 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 9824.2
Subtract 176 from 190 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
If we divide 140 by 88, we get 1 and a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 9824.21
The remainder is 52 after subtracting 88 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
When dividing 520 by 88, we get 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 9824.215
If we take 440 away from 520, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
88 can be fit into 800 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9824.2159
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.

Advancing to step 11:
88 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 9824.2159
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.

Advancing to step 12:
88 can be fit into 800 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 9824.215909
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.

On to step 13:
88 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 9824.215909
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.

Step 14:
88 goes into 800 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9824.21590909
If we take 792 away from 800, we end up 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.

The final outcome is 9824.21590909, with a leftover of 8e-09.
