319545 ÷ 66 
The aim is to understand the frequency of 66 in 319545.

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
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 66

Let's proceed to step 2:
31 divided by 66 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 66

Going ahead to step 3:
When dividing 319 by 66, we get 4 with a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 264 from 319 to get 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 66

Advancing to step 4:
If we divide 555 by 66, we get 8 and a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 528 from 555, we get 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 66

Let's proceed to step 5:
66 goes into 274 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
The remainder is 10 after subtracting 264 from 274.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 66

On to step 6:
66 goes into 105 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 4841.0
If we take 66 away from 105, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
390 divided by 66 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 4841.5
If we take 330 away from 390, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
66 goes into 600 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 4841.59
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4841.59
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 4841.5909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 4841.5909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
When dividing 600 by 66, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4841.590909
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
60 divided by 66 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 4841.590909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
66 can be fit into 600 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 4841.59090909
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 4841.59090909 and a remainder of 6e-09.
