159858 divided by 8 
We want to figure out the number of times 159858 can be divided by 8.

Moving on to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 8

Let's proceed to step 2:
8 can be fit into 15 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 8 from 15 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 8

On to step 3:
8 can be fit into 79 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 72 from 79, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 8

On to step 4:
The number 8 fits into 78 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 199.0
Subtract 72 from 78 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 8

Moving on to step 5:
65 divided by 8 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 1998.0
Deduct 64 from 65 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 8

Let's proceed to step 6:
8 goes into 18 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 19982.0
If we take 16 away from 18, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 8, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 19982.2
If we take 16 away from 20, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 19982.25
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.

Step 9:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19982.25
Subtracting 0 from 0 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.

Advancing to step 10:
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: 19982.25
The remainder is 0 after subtracting 0 from 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 result is 19982.25 with a remainder of 0.0.
