359731 divided by 66 
The aim is to understand the frequency of 66 in 359731.

Let's proceed to step 1:
When dividing 3 by 66, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 66

Advancing to step 2:
66 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 66

Let's proceed to step 3:
The number 66 fits into 359 5 times, leaving a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 330 from 359 leaves us with 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 66

Let's proceed to step 4:
297 divided by 66 is 4 with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 264 away from 297, we end up with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 66

Advancing to step 5:
66 can be fit into 333 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 545.0
If we take 330 away from 333, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 66

Going ahead to step 6:
When dividing 31 by 66, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 5450.0
If we take 0 away from 31, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
The number 66 fits into 310 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 5450.4
Deduct 264 from 310 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
When dividing 460 by 66, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5450.46
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
When dividing 640 by 66, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 5450.469
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 5450.4696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 5450.46969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
When dividing 460 by 66, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5450.469696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
640 divided by 66 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 5450.4696969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
When dividing 460 by 66, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5450.46969696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 5450.46969696 with a balance of 6.4e-08.
