211320 ÷ 66 
The aim is to understand the frequency of 66 in 211320.

Going ahead to step 1:
2 divided by 66 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 66

On to step 2:
When dividing 21 by 66, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 66

Moving on to step 3:
211 divided by 66 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 198 from 211, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 66

On to step 4:
66 goes into 133 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 132 away from 133, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 66

Moving on to step 5:
12 divided by 66 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 320.0
Subtract 0 from 12 to get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 66

Step 6:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 3201.0
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
If we divide 540 by 66, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 3201.8
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 66, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 3201.81
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
If we divide 540 by 66, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3201.818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 66, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 3201.8181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3201.81818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 3201.818181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
When dividing 540 by 66, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 3201.8181818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
66 can be fit into 120 1 times, resulting in a remainder of 54.
The next digit of our result is 1. 
Result so far: 3201.81818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 3201.81818181 with a balance of 5.4e-08.
