We're dividing 613603 by 26 
Let's see how many times 26 fits into 613603.

Step 1:
6 divided by 26 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 26

Going ahead to step 2:
26 can be fit into 61 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 52 away from 61, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 26

Step 3:
The number 26 fits into 93 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 78 from 93 and we're left with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 26

Going ahead to step 4:
26 goes into 156 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
Deduct 156 from 156 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 26

On to step 5:
26 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2360.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 26

Advancing to step 6:
26 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 23600.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
26 can be fit into 30 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 23600.1
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
26 goes into 40 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 23600.11
If we take 26 away from 40, 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.

Our division results in 23600.11 with a remaining 0.014.
