823066 ÷ 42 
The aim is to understand the frequency of 42 in 823066.

Advancing to step 1:
42 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 42

Moving on to step 2:
42 can be fit into 82 1 times, resulting in a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 82 to get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 42

Step 3:
42 goes into 403 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 378 away from 403, we end up with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 42

Step 4:
42 can be fit into 250 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Deduct 210 from 250 and we're left with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 42

Let's proceed to step 5:
42 goes into 406 9 times with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 1959.0
If we take 378 away from 406, we end up with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 42

Let's proceed to step 6:
The number 42 fits into 286 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 19596.0
Deduct 252 from 286 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
42 goes into 340 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 19596.8
Subtract 336 from 340 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.

Moving on to step 8:
40 divided by 42 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 19596.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
42 goes into 400 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 19596.809
If we subtract 378 from 400, we get 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 10:
220 divided by 42 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 19596.8095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 19596.80952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
42 goes into 160 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 19596.809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 19596.8095238
If we subtract 336 from 340, we 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.

On to step 14:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 19596.8095238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 19596.8095238 and a remainder of 4e-08.
