We divide 219550 by 66
The aim is to understand the frequency of 66 in 219550.

Moving on to step 1:
If we divide 2 by 66, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 66

Step 2:
66 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 66

Step 3:
The number 66 fits into 219 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 198 from 219 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 66

Step 4:
If we divide 215 by 66, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtract 198 from 215 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 66

Advancing to step 5:
66 goes into 175 2 times with a remainder of 43.
The next digit of our result is 2. 
Result so far: 332.0
Subtract 132 from 175 to get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 66

Going ahead to step 6:
The number 66 fits into 430 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 3326.0
Subtracting 396 from 430 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
66 can be fit into 340 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3326.5
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 66 is 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 3326.51
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 66, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3326.515
If we take 330 away from 340, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
66 goes into 100 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 3326.5151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
The number 66 fits into 340 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 3326.51515
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 66, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 3326.515151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
When dividing 340 by 66, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 3326.5151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 66, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 3326.51515151
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 3326.51515151 with a balance of 3.4e-08.
