Let's divide 419344 by 66
The aim is to understand the frequency of 66 in 419344.

Step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 66

Moving on to step 2:
66 can be fit into 41 0 times, resulting in a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 66

On to step 3:
When dividing 419 by 66, we get 6 with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 396 from 419 leaves us with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 66

Step 4:
66 goes into 233 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 198 from 233 to get 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 66

Advancing to step 5:
66 can be fit into 354 5 times, resulting in a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 635.0
Subtract 330 from 354 to get 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 66

Moving on to step 6:
When dividing 244 by 66, we get 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 6353.0
If we subtract 198 from 244, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
66 goes into 460 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 6353.6
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:
66 goes into 640 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 6353.69
If we subtract 594 from 640, we get 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 9:
460 divided by 66 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 6353.696
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.

Let's proceed to step 10:
66 goes into 640 9 times with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 6353.6969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
If we divide 460 by 66, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 6353.69696
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.

Advancing to step 12:
If we divide 640 by 66, we get 9 and a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 6353.696969
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.

On to step 13:
If we divide 460 by 66, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 6353.6969696
If we subtract 396 from 460, we 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.

Going ahead to step 14:
640 divided by 66 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 6353.69696969
Deduct 594 from 640 and we're left 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.

Our division results in 6353.69696969 with a remaining 4.6e-08.
