461653 ÷ 66 
The aim is to understand the frequency of 66 in 461653.

On to step 1:
If we divide 4 by 66, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 66

Step 2:
46 divided by 66 is 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 66

Going ahead to step 3:
When dividing 461 by 66, we get 6 with a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 396 from 461 to get 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 66

Advancing to step 4:
66 can be fit into 656 9 times, resulting in a remainder of 62.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 594 from 656 to get 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 66

Moving on to step 5:
625 divided by 66 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 699.0
Deduct 594 from 625 and we're left with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 66

On to step 6:
313 divided by 66 is 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 6994.0
Deduct 264 from 313 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
490 divided by 66 is 7 with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 6994.7
The remainder is 28 after subtracting 462 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
When dividing 280 by 66, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 6994.74
The remainder is 16 after subtracting 264 from 280.
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 9:
If we divide 160 by 66, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6994.742
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
280 divided by 66 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 6994.7424
Subtracting 264 from 280 leaves us 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.

Let's proceed to step 11:
The number 66 fits into 160 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6994.74242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 6994.742424
Subtracting 264 from 280 leaves us 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.

On to step 13:
If we divide 160 by 66, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6994.7424242
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
66 goes into 280 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 6994.74242424
If we take 264 away from 280, we end up 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.

The final outcome is 6994.74242424, with a leftover of 1.6e-08.
