355173 ÷ 26 
We want to figure out the number of times 355173 can be divided by 26.

Moving on to step 1:
If we divide 3 by 26, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 26

Advancing to step 2:
26 goes into 35 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 26 from 35 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 26

Moving on to step 3:
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: 13.0
If we take 78 away from 95, we end up with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 26

Advancing to step 4:
26 goes into 171 6 times with a remainder of 15.
The next digit of our result is 6. 
Result so far: 136.0
Subtract 156 from 171 to get 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 26

Going ahead to step 5:
157 divided by 26 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1366.0
Subtracting 156 from 157 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 26

Going ahead to step 6:
13 divided by 26 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 13660.0
If we take 0 away from 13, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
The number 26 fits into 130 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13660.5
Subtracting 130 from 130 leaves us with 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 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13660.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
26 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13660.5
Subtract 0 from 0 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.

The quotient of the division is 13660.5, and the remainder is 0.0.
