We're dividing 183908 by 73 
The aim is to understand the frequency of 73 in 183908.

Going ahead to step 1:
If we divide 1 by 73, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 73

Moving on to step 2:
73 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 73

On to step 3:
73 goes into 183 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 146 from 183 and we're left with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 73

On to step 4:
73 goes into 379 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 14 after subtracting 365 from 379.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 73

Let's proceed to step 5:
73 goes into 140 1 times with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
If we take 73 away from 140, we end up with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 73

Step 6:
678 divided by 73 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 2519.0
Subtract 657 from 678 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
210 divided by 73 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 2519.2
Subtract 146 from 210 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.

Moving on to step 8:
73 goes into 640 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 2519.28
If we take 584 away from 640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
73 goes into 560 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 2519.287
Subtracting 511 from 560 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
490 divided by 73 is 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 2519.2876
Subtract 438 from 490 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
When dividing 520 by 73, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 2519.28767
Subtracting 511 from 520 leaves us 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.

Step 12:
If we divide 90 by 73, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 2519.287671
The remainder is 17 after subtracting 73 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
When dividing 170 by 73, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2519.2876712
Deduct 146 from 170 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
The number 73 fits into 240 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 2519.28767123
Subtracting 219 from 240 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 2519.28767123 and a remainder of 2.1e-08.
