We look at the division of 134637 by 73 
The aim is to understand the frequency of 73 in 134637.

Let's proceed to step 1:
1 divided by 73 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 73

Advancing to step 2:
73 goes into 13 0 times 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.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 73

Let's proceed to step 3:
The number 73 fits into 134 1 times, leaving a remainder of 61.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 73 from 134 leaves us with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 73

On to step 4:
If we divide 616 by 73, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 18.0
If we take 584 away from 616, we end up with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 73

Going ahead to step 5:
If we divide 323 by 73, we get 4 and a remainder of 31.
The next digit of our result is 4. 
Result so far: 184.0
If we take 292 away from 323, we end up with 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 73

Step 6:
If we divide 317 by 73, we get 4 and a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 1844.0
If we take 292 away from 317, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
73 can be fit into 250 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 1844.3
Subtracting 219 from 250 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
310 divided by 73 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1844.34
Subtract 292 from 310 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
73 goes into 180 2 times with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 1844.342
The remainder is 34 after subtracting 146 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
When dividing 340 by 73, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 1844.3424
If we subtract 292 from 340, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
73 can be fit into 480 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 1844.34246
The remainder is 42 after subtracting 438 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
The number 73 fits into 420 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1844.342465
Subtract 365 from 420 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 13:
73 goes into 550 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 1844.3424657
If we subtract 511 from 550, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 14:
The number 73 fits into 390 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1844.34246575
Deduct 365 from 390 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 1844.34246575 with a remainder of 2.5e-08.
