We look at the division of 638701 by 83 
The aim is to understand the frequency of 83 in 638701.

Let's proceed to step 1:
83 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 83

On to step 2:
63 divided by 83 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 83

Let's proceed to step 3:
638 divided by 83 is 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 7.0
If we take 581 away from 638, we end up with 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 83

Advancing to step 4:
577 divided by 83 is 6 with a remainder of 79.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 498 from 577 and we're left with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 83

Advancing to step 5:
83 goes into 790 9 times with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 769.0
The remainder is 43 after subtracting 747 from 790.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 83

Let's proceed to step 6:
The number 83 fits into 431 5 times, leaving a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 7695.0
The remainder is 16 after subtracting 415 from 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
83 can be fit into 160 1 times, resulting in a remainder of 77.
The next digit of our result is 1. 
Result so far: 7695.1
Subtract 83 from 160 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 8:
The number 83 fits into 770 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 7695.19
Deduct 747 from 770 and we're left 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.

Advancing to step 9:
If we divide 230 by 83, we get 2 and a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 7695.192
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.

Going ahead to step 10:
83 can be fit into 640 7 times, resulting in a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 7695.1927
Deduct 581 from 640 and we're left 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.

Going ahead to step 11:
When dividing 590 by 83, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7695.19277
If we take 581 away from 590, we end up 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 7695.19277 with a remainder of 9e-06.
