474921 ÷ 66 
The aim is to understand the frequency of 66 in 474921.

Moving on to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 66

On to step 2:
66 goes into 47 0 times with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 66

Let's proceed to step 3:
66 can be fit into 474 7 times, resulting in a remainder of 12.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 462 from 474 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 66

Moving on to step 4:
The number 66 fits into 129 1 times, leaving a remainder of 63.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 63 after subtracting 66 from 129.
Include the next digit (2) from the dividend after 63, then repeat: 632 / 66

Going ahead to step 5:
When dividing 632 by 66, we get 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 719.0
The remainder is 38 after subtracting 594 from 632.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 66

Advancing to step 6:
If we divide 381 by 66, we get 5 and a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 7195.0
Subtracting 330 from 381 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
When dividing 510 by 66, we get 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 7195.7
The remainder is 48 after subtracting 462 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
If we divide 480 by 66, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 7195.77
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 7195.77, with a leftover of 0.018.
