We look at the division of 178537 by 83 
The aim is to understand the frequency of 83 in 178537.

Let's proceed to step 1:
1 divided by 83 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 83

Let's proceed to step 2:
83 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 83

Let's proceed to step 3:
The number 83 fits into 178 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 166 from 178, we get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 83

Going ahead to step 4:
When dividing 125 by 83, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 83 from 125, we get 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 83

Advancing to step 5:
83 can be fit into 423 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 215.0
The remainder is 8 after subtracting 415 from 423.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 83

Step 6:
If we divide 87 by 83, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 2151.0
If we subtract 83 from 87, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
83 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 2151.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
The number 83 fits into 400 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 2151.04
If we take 332 away from 400, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
680 divided by 83 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 2151.048
Subtracting 664 from 680 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
When dividing 160 by 83, we get 1 with a remainder of 77.
The next digit of our result is 1. 
Result so far: 2151.0481
Deduct 83 from 160 and we're left with 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 11:
770 divided by 83 is 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 2151.04819
Subtract 747 from 770 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
When dividing 230 by 83, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 2151.048192
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.

Going ahead to step 13:
83 can be fit into 640 7 times, resulting in a remainder of 59.
The next digit of our result is 7. 
Result so far: 2151.0481927
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.

Advancing to step 14:
When dividing 590 by 83, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 2151.04819277
If we subtract 581 from 590, we get 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 2151.04819277 with a remainder of 9e-09.
