Let's divide 181562 by 66
The aim is to understand the frequency of 66 in 181562.

Moving on to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 66

Going ahead to step 2:
If we divide 18 by 66, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 66

Let's proceed to step 3:
66 goes into 181 2 times with a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 132 from 181, we get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 66

Going ahead to step 4:
The number 66 fits into 495 7 times, leaving a remainder of 33.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 462 from 495 to get 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 66

Step 5:
When dividing 336 by 66, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 275.0
If we subtract 330 from 336, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 66

Step 6:
If we divide 62 by 66, we get 0 and a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 2750.0
If we subtract 0 from 62, we 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.

Going ahead to step 7:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 2750.9
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.

Going ahead to step 8:
66 can be fit into 260 3 times, resulting in a remainder of 62.
The next digit of our result is 3. 
Result so far: 2750.93
If we subtract 198 from 260, we 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.

Going ahead to step 9:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 2750.939
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 10:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 2750.9393
Subtracting 198 from 260 leaves us 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.

Let's proceed to step 11:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 2750.93939
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.

Advancing to step 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 2750.939393
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:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 2750.9393939
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.

Advancing to step 14:
If we divide 260 by 66, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 2750.93939393
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.

The quotient of the division is 2750.93939393, and the remainder is 6.2e-08.
