We divide 376107 by 66
The aim is to understand the frequency of 66 in 376107.

Step 1:
If we divide 3 by 66, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 66

Going ahead to step 2:
If we divide 37 by 66, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 66

Step 3:
66 can be fit into 376 5 times, resulting in a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 330 away from 376, we end up with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 66

Moving on to step 4:
The number 66 fits into 461 6 times, leaving a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 396 from 461 and we're left with 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 66

On to step 5:
If we divide 650 by 66, we get 9 and a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 569.0
If we subtract 594 from 650, we get 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 66

Moving on to step 6:
567 divided by 66 is 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 5698.0
If we subtract 528 from 567, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
66 goes into 390 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 5698.5
Deduct 330 from 390 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
The number 66 fits into 600 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 5698.59
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 66, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5698.59
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 66 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5698.5909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
60 divided by 66 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5698.5909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 66, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5698.590909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
60 divided by 66 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 5698.590909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 5698.59090909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 5698.59090909 with a remainder of 6e-09.
