We look at the division of 402988 by 26 
Our goal is to divide 402988 by 26.

On to step 1:
The number 26 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 26

On to step 2:
The number 26 fits into 40 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 26 from 40 to get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 26

Step 3:
26 can be fit into 142 5 times, resulting in a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 130 away from 142, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 26

Going ahead to step 4:
26 can be fit into 129 4 times, resulting in a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we take 104 away from 129, we end up with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 26

Advancing to step 5:
When dividing 258 by 26, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 1549.0
If we subtract 234 from 258, we get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 26

Let's proceed to step 6:
When dividing 248 by 26, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 15499.0
If we take 234 away from 248, we end up 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.

Going ahead to step 7:
The number 26 fits into 140 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15499.5
Subtract 130 from 140 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 26 fits into 100 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 15499.53
Subtract 78 from 100 to 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.

Moving on to step 9:
If we divide 220 by 26, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 15499.538
Subtracting 208 from 220 leaves us 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.

Going ahead to step 10:
When dividing 120 by 26, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 15499.5384
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
When dividing 160 by 26, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 15499.53846
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 12:
If we divide 40 by 26, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 15499.538461
Subtract 26 from 40 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
If we divide 140 by 26, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15499.5384615
Subtract 130 from 140 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
26 goes into 100 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 15499.53846153
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 15499.53846153 with a remainder of 2.2e-08.
