We look at the division of 37457 by 66 
The aim is to understand the frequency of 66 in 37457.

Moving on to step 1:
3 divided by 66 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 66

Advancing to step 2:
66 can be fit into 37 0 times, resulting in a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 66

Advancing to step 3:
If we divide 374 by 66, we get 5 and a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 330 from 374 leaves us with 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 66

Advancing to step 4:
445 divided by 66 is 6 with a remainder of 49.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 396 from 445, we get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 66

Let's proceed to step 5:
When dividing 497 by 66, we get 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 567.0
The remainder is 35 after subtracting 462 from 497.
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 6:
350 divided by 66 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 567.5
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 7:
When dividing 200 by 66, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 567.53
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.

Going ahead to step 8:
If we divide 20 by 66, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 567.53
Subtracting 0 from 20 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 9:
The number 66 fits into 200 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 567.5303
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.

Step 10:
20 divided by 66 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 567.5303
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 11:
When dividing 200 by 66, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 567.530303
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.

Let's proceed to step 12:
20 divided by 66 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 567.530303
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.

Advancing to step 13:
When dividing 200 by 66, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 567.53030303
Subtracting 198 from 200 leaves us 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.

In conclusion, the division gives 567.53030303 with a balance of 2e-09.
