We're dividing 13764909 by 73 
The aim is to understand the frequency of 73 in 13764909.

Step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 73

Advancing to step 2:
When dividing 13 by 73, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 73

Step 3:
When dividing 137 by 73, we get 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 73 from 137, we get 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 73

Going ahead to step 4:
The number 73 fits into 646 8 times, leaving a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 584 from 646 and we're left with 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 73

Going ahead to step 5:
If we divide 624 by 73, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
Deduct 584 from 624 and we're left with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 73

Step 6:
If we divide 409 by 73, we get 5 and a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 1885.0
If we take 365 away from 409, we end up with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 73

Going ahead to step 7:
440 divided by 73 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 18856.0
If we subtract 438 from 440, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 73

Step 8:
73 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 188560.0
Deduct 0 from 29 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
The number 73 fits into 290 3 times, leaving a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 188560.3
If we subtract 219 from 290, we get 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 10:
If we divide 710 by 73, we get 9 and a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 188560.39
Deduct 657 from 710 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
When dividing 530 by 73, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 188560.397
Subtract 511 from 530 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
73 can be fit into 190 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 188560.3972
The remainder is 44 after subtracting 146 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
If we divide 440 by 73, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 188560.39726
Deduct 438 from 440 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
If we divide 20 by 73, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 188560.39726
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
When dividing 200 by 73, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 188560.3972602
If we take 146 away from 200, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 16:
73 can be fit into 540 7 times, resulting in a remainder of 29.
The next digit of our result is 7. 
Result so far: 188560.39726027
Subtracting 511 from 540 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 188560.39726027, with a leftover of 2.9e-08.
