We divide 858891 by 88
We're looking to find how many times 88 goes into 858891.

Moving on to step 1:
88 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 88

Step 2:
If we divide 85 by 88, we get 0 and a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 88

Let's proceed to step 3:
When dividing 858 by 88, we get 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 792 away from 858, we end up with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 88

Advancing to step 4:
88 goes into 668 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtracting 616 from 668 leaves us with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 88

Let's proceed to step 5:
If we divide 529 by 88, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 976.0
If we subtract 528 from 529, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 88

Step 6:
88 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 9760.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 88, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 9760.1
The remainder is 22 after subtracting 88 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 88, we get 2 and a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 9760.12
If we take 176 away from 220, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
88 goes into 440 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9760.125
Deduct 440 from 440 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 88 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9760.125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
88 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 9760.125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9760.125, with a leftover of 0.0.
