We look at the division of 12475089 by 83 
The aim is to understand the frequency of 83 in 12475089.

Let's proceed to step 1:
If we divide 1 by 83, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 83

Advancing to step 2:
When dividing 12 by 83, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 83

Moving on to step 3:
When dividing 124 by 83, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 83 from 124 and we're left with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 83

Moving on to step 4:
If we divide 417 by 83, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 415 from 417, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 83

Advancing to step 5:
If we divide 25 by 83, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 150.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 83

Step 6:
If we divide 250 by 83, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1503.0
The remainder is 1 after subtracting 249 from 250.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 83

Step 7:
83 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 15030.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 83

Going ahead to step 8:
When dividing 189 by 83, we get 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 150302.0
If we take 166 away from 189, we end up with 23.
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 9:
If we divide 230 by 83, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 150302.2
Subtract 166 from 230 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
The number 83 fits into 640 7 times, leaving a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 150302.27
Subtracting 581 from 640 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 11:
The number 83 fits into 590 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 150302.277
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 result is 150302.277 with a remainder of 0.0009.
