99588 divided by 8 
Let's see how many times 8 fits into 99588.

Step 1:
8 goes into 9 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 8 away from 9, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 8

Advancing to step 2:
8 goes into 19 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 3 after subtracting 16 from 19.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 8

Step 3:
8 can be fit into 35 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 32 from 35 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 8

Going ahead to step 4:
When dividing 38 by 8, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1244.0
If we take 32 away from 38, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 8

Step 5:
If we divide 68 by 8, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 12448.0
The remainder is 4 after subtracting 64 from 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
If we divide 40 by 8, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 12448.5
If we take 40 away from 40, 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.

Step 7:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12448.5
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.

Moving on to step 8:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12448.5
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.

The final outcome is 12448.5, with a leftover of 0.0.
