We're dividing 450138 by 26 
We want to figure out the number of times 450138 can be divided by 26.

Going ahead to step 1:
When dividing 4 by 26, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 26

Going ahead to step 2:
When dividing 45 by 26, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 26 from 45 leaves us with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 26

On to step 3:
26 can be fit into 190 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 182 from 190 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 26

Step 4:
When dividing 81 by 26, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 173.0
If we subtract 78 from 81, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 26

Step 5:
26 goes into 33 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1731.0
Deduct 26 from 33 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 26

Step 6:
The number 26 fits into 78 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 17313.0
Subtract 78 from 78 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 26 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17313.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
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: 17313.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 17313.0 with a remainder of 0.0.
