266342 ÷ 19 
The aim is to understand the frequency of 19 in 266342.

Advancing to step 1:
19 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 19

Going ahead to step 2:
19 can be fit into 26 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 19 from 26 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 19

Step 3:
19 goes into 76 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 14.0
If we take 76 away from 76, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 19

Moving on to step 4:
19 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 19

Let's proceed to step 5:
19 goes into 34 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1401.0
Subtract 19 from 34 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 19

Step 6:
19 goes into 152 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 14018.0
The remainder is 0 after subtracting 152 from 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 19 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14018.0
Deduct 0 from 0 and we're left 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.

On to step 8:
When dividing 0 by 19, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14018.0
Deduct 0 from 0 and we're left 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.

The final result is 14018.0 with a remainder of 0.0.
