685112 divided by 83 
The aim is to understand the frequency of 83 in 685112.

Let's proceed to step 1:
When dividing 6 by 83, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 83

Moving on to step 2:
If we divide 68 by 83, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 83

Let's proceed to step 3:
685 divided by 83 is 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 21 after subtracting 664 from 685.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 83

On to step 4:
When dividing 211 by 83, we get 2 with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 166 from 211, we get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 83

Advancing to step 5:
83 can be fit into 451 5 times, resulting in a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 825.0
If we take 415 away from 451, we end up with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 83

On to step 6:
83 goes into 362 4 times with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 8254.0
The remainder is 30 after subtracting 332 from 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
83 goes into 300 3 times with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 8254.3
The remainder is 51 after subtracting 249 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 8:
83 can be fit into 510 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8254.36
The remainder is 12 after subtracting 498 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 83 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 8254.361
The remainder is 37 after subtracting 83 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
83 goes into 370 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 8254.3614
The remainder is 38 after subtracting 332 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
When dividing 380 by 83, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 8254.36144
Subtract 332 from 380 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 8254.36144 with a remainder of 4.8e-05.
