219171 ÷ 66 
The aim is to understand the frequency of 66 in 219171.

Advancing to step 1:
66 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 66

Step 2:
The number 66 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 66

Going ahead to step 3:
66 can be fit into 219 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 21 after subtracting 198 from 219.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 66

Going ahead to step 4:
211 divided by 66 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 198 from 211 and we're left with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 66

Advancing to step 5:
137 divided by 66 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 332.0
The remainder is 5 after subtracting 132 from 137.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 66

Going ahead to step 6:
When dividing 51 by 66, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 3320.0
The remainder is 51 after subtracting 0 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
66 can be fit into 510 7 times, resulting in a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 3320.7
Subtract 462 from 510 to get 48.
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:
66 can be fit into 480 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3320.77
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 3320.77 with a balance of 0.018.
