352817 ÷ 26 
The aim is to understand the frequency of 26 in 352817.

Going ahead to step 1:
When dividing 3 by 26, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 26

Step 2:
The number 26 fits into 35 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we take 26 away from 35, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 26

Step 3:
The number 26 fits into 92 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 78 from 92 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 26

On to step 4:
The number 26 fits into 148 5 times, leaving a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Deduct 130 from 148 and we're left with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 26

On to step 5:
181 divided by 26 is 6 with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 1356.0
If we take 156 away from 181, we end up with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 26

Advancing to step 6:
26 goes into 257 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 13569.0
Subtract 234 from 257 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
230 divided by 26 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 13569.8
Deduct 208 from 230 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.

Moving on to step 8:
26 can be fit into 220 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 13569.88
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.

Our division results in 13569.88 with a remaining 0.012.
