We look at the division of 375110 by 66 
The aim is to understand the frequency of 66 in 375110.

Moving on to step 1:
66 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 66

Moving on to step 2:
The number 66 fits into 37 0 times, leaving a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 66

On to step 3:
When dividing 375 by 66, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 330 from 375, we get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 66

Moving on to step 4:
451 divided by 66 is 6 with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 396 from 451 to get 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 66

Let's proceed to step 5:
551 divided by 66 is 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 568.0
If we take 528 away from 551, we end up with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 66

Step 6:
The number 66 fits into 230 3 times, leaving a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 5683.0
If we take 198 away from 230, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
320 divided by 66 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5683.4
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
560 divided by 66 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 5683.48
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 5683.484
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 66 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 5683.4848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
66 goes into 320 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 5683.48484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
66 goes into 560 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5683.484848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
If we divide 320 by 66, we get 4 and a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 5683.4848484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
When dividing 560 by 66, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 5683.48484848
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 5683.48484848, with a leftover of 3.2e-08.
