946079 divided by 66 
The aim is to understand the frequency of 66 in 946079.

On to step 1:
9 divided by 66 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 66

Let's proceed to step 2:
The number 66 fits into 94 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 66 from 94 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 66

Moving on to step 3:
When dividing 286 by 66, we get 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 22 after subtracting 264 from 286.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 66

Advancing to step 4:
220 divided by 66 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Deduct 198 from 220 and we're left with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 66

Advancing to step 5:
66 can be fit into 227 3 times, resulting in a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 1433.0
If we subtract 198 from 227, we get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 66

Going ahead to step 6:
When dividing 299 by 66, we get 4 with a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 14334.0
If we take 264 away from 299, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
66 can be fit into 350 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 14334.5
Subtracting 330 from 350 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 66 fits into 200 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 14334.53
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
66 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14334.53
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
200 divided by 66 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 14334.5303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 14334.5303
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
66 goes into 200 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 14334.530303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 14334.530303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
66 goes into 200 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 14334.53030303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 14334.53030303, with a leftover of 2e-09.
