We look at the division of 30345715 by 211 
The aim is to understand the frequency of 211 in 30345715.

Going ahead to step 1:
If we divide 3 by 211, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 211

Advancing to step 2:
If we divide 30 by 211, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 211

Let's proceed to step 3:
If we divide 303 by 211, we get 1 and a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 211 from 303 and we're left with 92.
Bring next digit (4) of the dividend behind the 92 and repeat the process: 924 / 211

Moving on to step 4:
If we divide 924 by 211, we get 4 and a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 844 from 924 leaves us with 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 211

On to step 5:
The number 211 fits into 805 3 times, leaving a remainder of 172.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtract 633 from 805 to get 172.
Take the next digit (7) from the dividend and append it to 172, then repeat: 1727 / 211

Going ahead to step 6:
If we divide 1727 by 211, we get 8 and a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 1438.0
Deduct 1688 from 1727 and we're left with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 211

Advancing to step 7:
211 goes into 391 1 times with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 14381.0
The remainder is 180 after subtracting 211 from 391.
Grab the next digit (5) from the dividend, add it to 180, then carry on: 1805 / 211

Step 8:
211 can be fit into 1805 8 times, resulting in a remainder of 117.
Put 8 as the next digit of the answer. 
Result so far: 143818.0
Subtract 1688 from 1805 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
The number 211 fits into 1170 5 times, leaving a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 143818.5
The remainder is 115 after subtracting 1055 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 10:
211 can be fit into 1150 5 times, resulting in a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 143818.55
If we take 1055 away from 1150, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final outcome is 143818.55, with a leftover of 0.095.
