We divide 359212 by 66
The aim is to understand the frequency of 66 in 359212.

On to step 1:
When dividing 3 by 66, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 66

Moving on to step 2:
35 divided by 66 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 66

Moving on to step 3:
66 can be fit into 359 5 times, resulting in a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 330 from 359, we get 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 66

Step 4:
66 goes into 292 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 264 away from 292, we end up with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 66

Let's proceed to step 5:
If we divide 281 by 66, we get 4 and a remainder of 17.
The next digit of our result is 4. 
Result so far: 544.0
Deduct 264 from 281 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 66

On to step 6:
66 goes into 172 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 5442.0
The remainder is 40 after subtracting 132 from 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
400 divided by 66 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 5442.6
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 66, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5442.6
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 5442.606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
66 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5442.606
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
66 goes into 400 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 5442.60606
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 66 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5442.60606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
If we divide 400 by 66, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 5442.6060606
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
66 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5442.6060606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 5442.6060606 and a remainder of 4e-08.
