We divide 305815 by 83
The aim is to understand the frequency of 83 in 305815.

Let's proceed to step 1:
If we divide 3 by 83, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 83

Let's proceed to step 2:
83 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 83

Let's proceed to step 3:
When dividing 305 by 83, we get 3 with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 249 from 305, we get 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 83

On to step 4:
If we divide 568 by 83, we get 6 and a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 498 from 568 and we're left with 70.
Grab the next digit (1) from the dividend, add it to 70, then carry on: 701 / 83

Let's proceed to step 5:
83 can be fit into 701 8 times, resulting in a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 368.0
If we take 664 away from 701, we end up with 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 83

Advancing to step 6:
If we divide 375 by 83, we get 4 and a remainder of 43.
The next digit of our result is 4. 
Result so far: 3684.0
Subtract 332 from 375 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
When dividing 430 by 83, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3684.5
If we take 415 away from 430, we end up with 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 8:
83 can be fit into 150 1 times, resulting in a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 3684.51
Subtracting 83 from 150 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 3684.518
Subtracting 664 from 670 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
83 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3684.518
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
The number 83 fits into 600 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 3684.51807
Subtract 581 from 600 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
83 goes into 190 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 3684.518072
Deduct 166 from 190 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
If we divide 240 by 83, we get 2 and a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 3684.5180722
Deduct 166 from 240 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

In conclusion, the division gives 3684.5180722 with a balance of 7.4e-07.
