We look at the division of 245122 by 66 
The aim is to understand the frequency of 66 in 245122.

Let's proceed to step 1:
66 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 66

Let's proceed to step 2:
When dividing 24 by 66, we get 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 66

Advancing to step 3:
When dividing 245 by 66, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 47 after subtracting 198 from 245.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 66

Moving on to step 4:
66 goes into 471 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 462 from 471 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 66

Let's proceed to step 5:
If we divide 92 by 66, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 371.0
If we subtract 66 from 92, we get 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 66

Let's proceed to step 6:
The number 66 fits into 262 3 times, leaving a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 3713.0
Deduct 198 from 262 and we're left 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 7:
66 can be fit into 640 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 3713.9
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 8:
When dividing 460 by 66, we get 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 3713.96
The remainder is 64 after subtracting 396 from 460.
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 9:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 3713.969
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.

On to step 10:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 3713.9696
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.

Advancing to step 11:
640 divided by 66 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 3713.96969
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.

Advancing to step 12:
The number 66 fits into 460 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3713.969696
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 13:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 3713.9696969
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.

Let's proceed to step 14:
460 divided by 66 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 3713.96969696
Subtracting 396 from 460 leaves us 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.

The quotient of the division is 3713.96969696, and the remainder is 6.4e-08.
