We're dividing 66450384 by 211 
The aim is to understand the frequency of 211 in 66450384.

Going ahead to step 1:
If we divide 6 by 211, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 211

Let's proceed to step 2:
When dividing 66 by 211, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 211

Moving on to step 3:
If we divide 664 by 211, we get 3 and a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 633 from 664 leaves us with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 211

Advancing to step 4:
When dividing 315 by 211, we get 1 with a remainder of 104.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 211 from 315 leaves us with 104.
Fetch the next digit (0) from the dividend, attach it to 104 and continue: 1040 / 211

Moving on to step 5:
The number 211 fits into 1040 4 times, leaving a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 314.0
Subtract 844 from 1040 to get 196.
Bring next digit (3) of the dividend behind the 196 and repeat the process: 1963 / 211

Advancing to step 6:
211 can be fit into 1963 9 times, resulting in a remainder of 64.
Record the quotient 9 as the next digit in the result. 
Result so far: 3149.0
Subtracting 1899 from 1963 leaves us with 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 211

Step 7:
When dividing 648 by 211, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 31493.0
Subtracting 633 from 648 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 211

Going ahead to step 8:
154 divided by 211 is 0 with a remainder of 154.
Record the quotient 0 as the next digit in the result. 
Result so far: 314930.0
Deduct 0 from 154 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
The number 211 fits into 1540 7 times, leaving a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 314930.7
The remainder is 63 after subtracting 1477 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 10:
211 can be fit into 630 2 times, resulting in a remainder of 208.
The next digit of our result is 2. 
Result so far: 314930.72
If we subtract 422 from 630, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 11:
When dividing 2080 by 211, we get 9 with a remainder of 181.
Put 9 as the next digit of the answer. 
Result so far: 314930.729
The remainder is 181 after subtracting 1899 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 12:
The number 211 fits into 1810 8 times, leaving a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 314930.7298
Deduct 1688 from 1810 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 13:
The number 211 fits into 1220 5 times, leaving a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 314930.72985
Deduct 1055 from 1220 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 14:
211 can be fit into 1650 7 times, resulting in a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 314930.729857
If we subtract 1477 from 1650, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 15:
If we divide 1730 by 211, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 314930.7298578
Subtracting 1688 from 1730 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 16:
211 goes into 420 1 times with a remainder of 209.
The next digit of our result is 1. 
Result so far: 314930.72985781
If we take 211 away from 420, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Our division results in 314930.72985781 with a remaining 2.09e-07.
