81776897 ÷ 211 
The aim is to understand the frequency of 211 in 81776897.

On to step 1:
When dividing 8 by 211, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 211

On to step 2:
81 divided by 211 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 211

Advancing to step 3:
211 goes into 817 3 times with a remainder of 184.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 633 from 817, we get 184.
Take the next digit (7) from the dividend and append it to 184, then repeat: 1847 / 211

Step 4:
When dividing 1847 by 211, we get 8 with a remainder of 159.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 1688 from 1847 to get 159.
Include the next digit (6) from the dividend after 159, then repeat: 1596 / 211

Moving on to step 5:
If we divide 1596 by 211, we get 7 and a remainder of 119.
Put 7 as the next digit of the answer. 
Result so far: 387.0
Subtracting 1477 from 1596 leaves us with 119.
Include the next digit (8) from the dividend after 119, then repeat: 1198 / 211

Going ahead to step 6:
When dividing 1198 by 211, we get 5 with a remainder of 143.
Use 5 as the next digit of our solution. 
Result so far: 3875.0
Subtracting 1055 from 1198 leaves us with 143.
Take the next digit (9) from the dividend and append it to 143, then repeat: 1439 / 211

On to step 7:
211 can be fit into 1439 6 times, resulting in a remainder of 173.
Record the quotient 6 as the next digit in the result. 
Result so far: 38756.0
Subtract 1266 from 1439 to get 173.
Fetch the next digit (7) from the dividend, attach it to 173 and continue: 1737 / 211

Advancing to step 8:
1737 divided by 211 is 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 387568.0
Subtract 1688 from 1737 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
211 goes into 490 2 times with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 387568.2
Subtracting 422 from 490 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
211 goes into 680 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 387568.23
The remainder is 47 after subtracting 633 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
The number 211 fits into 470 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 387568.232
Deduct 422 from 470 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
480 divided by 211 is 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 387568.2322
If we take 422 away from 480, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 387568.2322 and a remainder of 0.00058.
