We're dividing 135563 by 73 
The aim is to understand the frequency of 73 in 135563.

Moving on to step 1:
1 divided by 73 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 73

Step 2:
73 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 73

Step 3:
When dividing 135 by 73, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 73 from 135 and we're left with 62.
Take the next digit (5) from the dividend and append it to 62, then repeat: 625 / 73

Step 4:
625 divided by 73 is 8 with a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 584 from 625 to get 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 73

Let's proceed to step 5:
73 goes into 416 5 times with a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we take 365 away from 416, we end up with 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 73

Let's proceed to step 6:
If we divide 513 by 73, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 1857.0
The remainder is 2 after subtracting 511 from 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
73 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1857.0
Subtracting 0 from 20 leaves us 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.

Step 8:
73 can be fit into 200 2 times, resulting in a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 1857.02
Subtract 146 from 200 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
The number 73 fits into 540 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 1857.027
If we subtract 511 from 540, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
The number 73 fits into 290 3 times, leaving a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 1857.0273
Deduct 219 from 290 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 11:
73 goes into 710 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 1857.02739
If we subtract 657 from 710, we get 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 12:
The number 73 fits into 530 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 1857.027397
The remainder is 19 after subtracting 511 from 530.
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 13:
73 can be fit into 190 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1857.0273972
Subtract 146 from 190 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
When dividing 440 by 73, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1857.02739726
The remainder is 2 after subtracting 438 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 1857.02739726, with a leftover of 2e-09.
