We look at the division of 18634691 by 211 
The aim is to understand the frequency of 211 in 18634691.

Advancing to step 1:
When dividing 1 by 211, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 211

Going ahead to step 2:
If we divide 18 by 211, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 211

On to step 3:
211 can be fit into 186 0 times, resulting in a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Append the next digit (3) from the dividend to 186 and continue with: 1863 / 211

Moving on to step 4:
When dividing 1863 by 211, we get 8 with a remainder of 175.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 175 after subtracting 1688 from 1863.
Include the next digit (4) from the dividend after 175, then repeat: 1754 / 211

Advancing to step 5:
When dividing 1754 by 211, we get 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 66 after subtracting 1688 from 1754.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 211

Moving on to step 6:
666 divided by 211 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 883.0
If we subtract 633 from 666, we get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 211

Moving on to step 7:
339 divided by 211 is 1 with a remainder of 128.
Put 1 as the next digit of the answer. 
Result so far: 8831.0
Subtract 211 from 339 to get 128.
Take the next digit (1) from the dividend and append it to 128, then repeat: 1281 / 211

Step 8:
1281 divided by 211 is 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 88316.0
If we subtract 1266 from 1281, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
If we divide 150 by 211, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 88316.0
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
The number 211 fits into 1500 7 times, leaving a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 88316.07
If we take 1477 away from 1500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
211 goes into 230 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 88316.071
Deduct 211 from 230 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
190 divided by 211 is 0 with a remainder of 190.
The next digit of our result is 0. 
Result so far: 88316.071
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
When dividing 1900 by 211, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 88316.07109
If we subtract 1899 from 1900, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
10 divided by 211 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 88316.07109
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
If we divide 100 by 211, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 88316.07109
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 88316.07109 with a remainder of 1e-06.
