We look at the division of 15911756 by 26 
We want to divide 15911756 by 26.

On to step 1:
26 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 26

Moving on to step 2:
The number 26 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 26

Advancing to step 3:
26 can be fit into 159 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 156 from 159 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 26

On to step 4:
The number 26 fits into 31 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we take 26 away from 31, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 26

On to step 5:
When dividing 51 by 26, we get 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 611.0
Deduct 26 from 51 and we're left with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 26

On to step 6:
26 can be fit into 257 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 6119.0
Deduct 234 from 257 and we're left with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 26

Step 7:
235 divided by 26 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 61199.0
Deduct 234 from 235 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 26

Let's proceed to step 8:
26 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 611990.0
The remainder is 16 after subtracting 0 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
26 goes into 160 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 611990.6
Subtracting 156 from 160 leaves us 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.

On to step 10:
40 divided by 26 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 611990.61
The remainder is 14 after subtracting 26 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
If we divide 140 by 26, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 611990.615
Deduct 130 from 140 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
26 can be fit into 100 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 611990.6153
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
When dividing 220 by 26, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 611990.61538
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.

Going ahead to step 14:
120 divided by 26 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 611990.615384
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
26 can be fit into 160 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 611990.6153846
If we take 156 away from 160, 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 16:
26 can be fit into 40 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 611990.61538461
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 611990.61538461, and the remainder is 1.4e-08.
