432224 ÷ 66 
The aim is to understand the frequency of 66 in 432224.

On to step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 66

On to step 2:
If we divide 43 by 66, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 66

Step 3:
66 goes into 432 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 396 from 432 leaves us with 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 66

Step 4:
362 divided by 66 is 5 with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we subtract 330 from 362, we get 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 66

On to step 5:
66 goes into 322 4 times with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 654.0
The remainder is 58 after subtracting 264 from 322.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 66

Let's proceed to step 6:
If we divide 584 by 66, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 6548.0
Subtract 528 from 584 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
The number 66 fits into 560 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 6548.8
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
If we divide 320 by 66, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 6548.84
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 66 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 6548.848
Deduct 528 from 560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
66 can be fit into 320 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 6548.8484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
If we divide 560 by 66, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6548.84848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
320 divided by 66 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 6548.848484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
When dividing 560 by 66, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6548.8484848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 6548.84848484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 6548.84848484, with a leftover of 5.6e-08.
