We look at the division of 989220 by 73 
The aim is to understand the frequency of 73 in 989220.

Moving on to step 1:
9 divided by 73 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 73

Let's proceed to step 2:
The number 73 fits into 98 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 25 after subtracting 73 from 98.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 73

Step 3:
The number 73 fits into 259 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 219 from 259 and we're left with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 73

On to step 4:
The number 73 fits into 402 5 times, leaving a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 135.0
If we subtract 365 from 402, we get 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 73

Moving on to step 5:
The number 73 fits into 372 5 times, leaving a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 1355.0
Deduct 365 from 372 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 73

Step 6:
70 divided by 73 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 13550.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 13550.9
The remainder is 43 after subtracting 657 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
430 divided by 73 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 13550.95
Subtracting 365 from 430 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
73 goes into 650 8 times with a remainder of 66.
The next digit of our result is 8. 
Result so far: 13550.958
Subtracting 584 from 650 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
73 can be fit into 660 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 13550.9589
The remainder is 3 after subtracting 657 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
73 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 13550.9589
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
73 goes into 300 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13550.958904
Subtract 292 from 300 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
The number 73 fits into 80 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 13550.9589041
Deduct 73 from 80 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
When dividing 70 by 73, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 13550.9589041
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 13550.9589041, with a leftover of 7e-08.
