426142 divided by 66 
The aim is to understand the frequency of 66 in 426142.

Going ahead to step 1:
66 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 66

Moving on to step 2:
If we divide 42 by 66, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 66

Let's proceed to step 3:
66 goes into 426 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 396 from 426, we get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 66

Step 4:
The number 66 fits into 301 4 times, leaving a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 264 from 301 leaves us with 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 66

Moving on to step 5:
66 can be fit into 374 5 times, resulting in a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 645.0
Deduct 330 from 374 and we're left with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 66

Moving on to step 6:
66 goes into 442 6 times with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 6456.0
Deduct 396 from 442 and we're left with 46.

Use 6 as the next digit of our solution. 
Result so far: 6456.6
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
640 divided by 66 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 6456.69
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
460 divided by 66 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 6456.696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 6456.6969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
The number 66 fits into 460 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 6456.69696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
When dividing 640 by 66, we get 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 6456.696969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
If we divide 460 by 66, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 6456.6969696
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 6456.69696969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.
