323990 divided by 66 
The aim is to understand the frequency of 66 in 323990.

Let's proceed 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.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 66

Let's proceed to step 2:
32 divided by 66 is 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 66

Going ahead to step 3:
When dividing 323 by 66, we get 4 with a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 264 from 323 and we're left with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 66

Advancing to step 4:
66 can be fit into 599 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 5 after subtracting 594 from 599.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 66

Moving on to step 5:
If we divide 59 by 66, we get 0 and a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 490.0
Deduct 0 from 59 and we're left with 59.
Fetch the next digit (0) from the dividend, attach it to 59 and continue: 590 / 66

Advancing to step 6:
If we divide 590 by 66, we get 8 and a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 4908.0
Deduct 528 from 590 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
If we divide 620 by 66, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 4908.9
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
If we divide 260 by 66, we get 3 and a remainder of 62.
The next digit of our result is 3. 
Result so far: 4908.93
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
When dividing 620 by 66, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 4908.939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
When dividing 260 by 66, we get 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 4908.9393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
The number 66 fits into 620 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 4908.93939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 4908.939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
When dividing 620 by 66, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 4908.9393939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
If we divide 260 by 66, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 4908.93939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 4908.93939393, and the remainder is 6.2e-08.
