610991 divided by 83 
The aim is to understand the frequency of 83 in 610991.

Going ahead to step 1:
The number 83 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 83

Step 2:
The number 83 fits into 61 0 times, leaving a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 83

Moving on to step 3:
610 divided by 83 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 581 from 610 to get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 83

Going ahead to step 4:
If we divide 299 by 83, we get 3 and a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 249 from 299 leaves us with 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 83

On to step 5:
When dividing 509 by 83, we get 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 736.0
If we subtract 498 from 509, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 83

Going ahead to step 6:
When dividing 111 by 83, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 7361.0
If we take 83 away from 111, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 83, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 7361.3
Subtracting 249 from 280 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 8:
310 divided by 83 is 3 with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 7361.33
The remainder is 61 after subtracting 249 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 7361.33 with a remaining 0.061.
