We look at the division of 142875 by 83 
The aim is to understand the frequency of 83 in 142875.

Step 1:
1 divided by 83 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 83

Moving on to step 2:
83 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 83

Going ahead to step 3:
When dividing 142 by 83, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 83 away from 142, we end up with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 83

On to step 4:
If we divide 598 by 83, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 581 from 598 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 83

Moving on to step 5:
83 goes into 177 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtracting 166 from 177 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 83

Let's proceed to step 6:
83 can be fit into 115 1 times, resulting in a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1721.0
If we take 83 away from 115, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
When dividing 320 by 83, we get 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 1721.3
Subtracting 249 from 320 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 8:
83 goes into 710 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 1721.38
Deduct 664 from 710 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
83 goes into 460 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1721.385
Subtract 415 from 460 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
When dividing 450 by 83, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1721.3855
If we take 415 away from 450, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 1721.3855, and the remainder is 0.00035.
