19159 ÷ 26 
Let's see how many times 26 fits into 19159.

Let's proceed to step 1:
1 divided by 26 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 26

Let's proceed to step 2:
If we divide 19 by 26, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 26

Going ahead to step 3:
The number 26 fits into 191 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 182 from 191 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 26

Going ahead to step 4:
When dividing 95 by 26, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 78 from 95 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 26

Advancing to step 5:
When dividing 179 by 26, we get 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 736.0
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.

Moving on to step 6:
230 divided by 26 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 736.8
The remainder is 22 after subtracting 208 from 230.
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 7:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 736.88
If we take 208 away from 220, we end up with 12.
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 result is 736.88 with a remainder of 0.012.
