128889 ÷ 73 
The aim is to understand the frequency of 73 in 128889.

On to step 1:
If we divide 1 by 73, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 73

Step 2:
When dividing 12 by 73, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 73

Moving on to step 3:
The number 73 fits into 128 1 times, leaving a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 73 from 128, we get 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 73

Moving on to step 4:
558 divided by 73 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 511 from 558, we get 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 73

Step 5:
If we divide 478 by 73, we get 6 and a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
If we subtract 438 from 478, we get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 73

Let's proceed to step 6:
409 divided by 73 is 5 with a remainder of 44.
The next digit of our result is 5. 
Result so far: 1765.0
If we take 365 away from 409, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
73 can be fit into 440 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1765.6
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 8:
73 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 1765.6
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 73 is 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 1765.602
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.

Going ahead to step 10:
The number 73 fits into 540 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1765.6027
The remainder is 29 after subtracting 511 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
The number 73 fits into 290 3 times, leaving a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 1765.60273
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.

Going ahead to step 12:
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: 1765.602739
The remainder is 53 after subtracting 657 from 710.
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 13:
The number 73 fits into 530 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 1765.6027397
Deduct 511 from 530 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
73 goes into 190 2 times with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 1765.60273972
Subtracting 146 from 190 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 1765.60273972, with a leftover of 4.4e-08.
