We divide 839070 by 83
The aim is to understand the frequency of 83 in 839070.

Let's proceed to step 1:
83 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 83

Going ahead to step 2:
83 can be fit into 83 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 83 from 83, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 83

Let's proceed to step 3:
If we divide 9 by 83, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 83

On to step 4:
The number 83 fits into 90 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we subtract 83 from 90, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 83

On to step 5:
The number 83 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 1010.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 83

Let's proceed to step 6:
If we divide 770 by 83, we get 9 and a remainder of 23.
The next digit of our result is 9. 
Result so far: 10109.0
The remainder is 23 after subtracting 747 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
83 can be fit into 230 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 10109.2
Deduct 166 from 230 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
83 goes into 640 7 times with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 10109.27
Subtract 581 from 640 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
The number 83 fits into 590 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 10109.277
Deduct 581 from 590 and we're left 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.

The final outcome is 10109.277, with a leftover of 0.0009.
