89399 divided by 8 
We want to figure out the number of times 89399 can be divided by 8.

Advancing to step 1:
If we divide 8 by 8, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 8

Going ahead to step 2:
The number 8 fits into 9 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 8 from 9 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 8

Advancing to step 3:
8 can be fit into 13 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 111.0
The remainder is 5 after subtracting 8 from 13.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 8

Let's proceed to step 4:
If we divide 59 by 8, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 1117.0
If we take 56 away from 59, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 8

Step 5:
39 divided by 8 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 11174.0
Subtract 32 from 39 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 6:
The number 8 fits into 70 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 11174.8
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 11174.87
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11174.875
Subtracting 40 from 40 leaves us 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.

Let's proceed to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11174.875
If we take 0 away from 0, we end up 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 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11174.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 11174.875 with a balance of 0.0.
