578159 ÷ 26 
We want to figure out the number of times 578159 can be divided by 26.

Moving on to step 1:
When dividing 5 by 26, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 26

On to step 2:
26 can be fit into 57 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 52 from 57 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 26

On to step 3:
26 can be fit into 58 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 52 from 58, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 26

Let's proceed to step 4:
If we divide 61 by 26, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 222.0
Subtract 52 from 61 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 26

Moving on to step 5:
When dividing 95 by 26, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 2223.0
If we subtract 78 from 95, we get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 26

Let's proceed to step 6:
The number 26 fits into 179 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 22236.0
If we take 156 away from 179, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 26 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 22236.8
If we subtract 208 from 230, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
26 can be fit into 220 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 22236.88
The remainder is 12 after subtracting 208 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 22236.88, with a leftover of 0.012.
