We divide 213748 by 83
The aim is to understand the frequency of 83 in 213748.

Going ahead to step 1:
When dividing 2 by 83, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 83

On to step 2:
If we divide 21 by 83, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 83

Moving on to step 3:
The number 83 fits into 213 2 times, leaving a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 166 from 213 to get 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 83

Step 4:
83 can be fit into 477 5 times, resulting in a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 415 from 477 and we're left with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 83

Step 5:
If we divide 624 by 83, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 257.0
Subtract 581 from 624 to get 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 83

Moving on to step 6:
When dividing 438 by 83, we get 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 2575.0
The remainder is 23 after subtracting 415 from 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
When dividing 230 by 83, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 2575.2
Subtract 166 from 230 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
The number 83 fits into 640 7 times, leaving a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 2575.27
The remainder is 59 after subtracting 581 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
83 can be fit into 590 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 2575.277
Subtracting 581 from 590 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 2575.277 and a remainder of 0.0009.
