We look at the division of 994435 by 83 
The aim is to understand the frequency of 83 in 994435.

Step 1:
The number 83 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 83

Going ahead to step 2:
The number 83 fits into 99 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we take 83 away from 99, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 83

Advancing to step 3:
83 goes into 164 1 times with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 83 away from 164, we end up with 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 83

Advancing to step 4:
The number 83 fits into 814 9 times, leaving a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Deduct 747 from 814 and we're left with 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 83

Going ahead to step 5:
When dividing 673 by 83, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 1198.0
Subtract 664 from 673 to get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 83

Step 6:
83 goes into 95 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 11981.0
Subtract 83 from 95 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
83 goes into 120 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 11981.1
Subtracting 83 from 120 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
If we divide 370 by 83, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 11981.14
If we subtract 332 from 370, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
If we divide 380 by 83, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 11981.144
If we subtract 332 from 380, we 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 quotient of the division is 11981.144, and the remainder is 0.0048.
