We look at the division of 188893 by 73 
The aim is to understand the frequency of 73 in 188893.

Advancing to step 1:
If we divide 1 by 73, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 73

Going ahead to step 2:
73 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 73

Advancing to step 3:
73 goes into 188 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 42 after subtracting 146 from 188.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 73

On to step 4:
If we divide 428 by 73, we get 5 and a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 365 from 428 and we're left with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 73

Advancing to step 5:
73 goes into 639 8 times with a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
If we take 584 away from 639, we end up with 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 73

Step 6:
When dividing 553 by 73, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 2587.0
If we subtract 511 from 553, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
420 divided by 73 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 2587.5
If we subtract 365 from 420, we 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 8:
If we divide 550 by 73, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 2587.57
Deduct 511 from 550 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
73 can be fit into 390 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2587.575
If we take 365 away from 390, 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.

Step 10:
The number 73 fits into 250 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 2587.5753
The remainder is 31 after subtracting 219 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
The number 73 fits into 310 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 2587.57534
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 12:
180 divided by 73 is 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 2587.575342
Subtracting 146 from 180 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
73 goes into 340 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 2587.5753424
Subtracting 292 from 340 leaves us with 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 14:
When dividing 480 by 73, we get 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 2587.57534246
Subtracting 438 from 480 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 2587.57534246, with a leftover of 4.2e-08.
