Let's divide 381698 by 66
The aim is to understand the frequency of 66 in 381698.

Advancing to step 1:
66 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 66

Let's proceed to step 2:
38 divided by 66 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 66

Let's proceed to step 3:
The number 66 fits into 381 5 times, leaving a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 330 from 381 to get 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 66

Let's proceed to step 4:
66 goes into 516 7 times with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 462 from 516 to get 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 66

Let's proceed to step 5:
66 can be fit into 549 8 times, resulting in a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 578.0
The remainder is 21 after subtracting 528 from 549.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 66

Going ahead to step 6:
The number 66 fits into 218 3 times, leaving a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 5783.0
The remainder is 20 after subtracting 198 from 218.
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:
66 goes into 200 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 5783.3
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 8:
The number 66 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 5783.3
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.

Let's proceed to step 9:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 5783.303
If we take 198 away from 200, we end up 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.

Step 10:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5783.303
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.

Step 11:
66 goes into 200 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 5783.30303
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.

Going ahead to step 12:
20 divided by 66 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5783.30303
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.

Moving on to step 13:
When dividing 200 by 66, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 5783.3030303
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.

Moving on to step 14:
The number 66 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5783.3030303
Subtract 0 from 20 to 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.

In conclusion, the division gives 5783.3030303 with a balance of 2e-08.
