78338800 ÷ 211 
The aim is to understand the frequency of 211 in 78338800.

Advancing to step 1:
When dividing 7 by 211, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 211

Let's proceed to step 2:
211 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 211

Let's proceed to step 3:
211 can be fit into 783 3 times, resulting in a remainder of 150.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 633 away from 783, we end up with 150.
Include the next digit (3) from the dividend after 150, then repeat: 1503 / 211

Going ahead to step 4:
211 can be fit into 1503 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 26 after subtracting 1477 from 1503.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 211

Going ahead to step 5:
211 can be fit into 268 1 times, resulting in a remainder of 57.
The next digit of our result is 1. 
Result so far: 371.0
If we subtract 211 from 268, we get 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 211

Step 6:
211 goes into 578 2 times with a remainder of 156.
Record the quotient 2 as the next digit in the result. 
Result so far: 3712.0
If we subtract 422 from 578, we get 156.
Include the next digit (0) from the dividend after 156, then repeat: 1560 / 211

On to step 7:
1560 divided by 211 is 7 with a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 37127.0
The remainder is 83 after subtracting 1477 from 1560.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 211

Going ahead to step 8:
The number 211 fits into 830 3 times, leaving a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 371273.0
If we subtract 633 from 830, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 9:
The number 211 fits into 1970 9 times, leaving a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 371273.9
Subtracting 1899 from 1970 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 10:
211 can be fit into 710 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 371273.93
If we subtract 633 from 710, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 11:
211 goes into 770 3 times with a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 371273.933
Subtract 633 from 770 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

After the division, we end up with 371273.933 and a remainder of 0.0137.
