We look at the division of 983280 by 73 
The aim is to understand the frequency of 73 in 983280.

Moving on to step 1:
The number 73 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 73

On to step 2:
If we divide 98 by 73, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 73 away from 98, we end up with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 73

Going ahead to step 3:
If we divide 253 by 73, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 219 from 253, we get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 73

Moving on to step 4:
If we divide 342 by 73, we get 4 and a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Deduct 292 from 342 and we're left with 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 73

On to step 5:
73 goes into 508 6 times with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 1346.0
Subtracting 438 from 508 leaves us with 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 73

Going ahead to step 6:
The number 73 fits into 700 9 times, leaving a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 13469.0
Deduct 657 from 700 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
If we divide 430 by 73, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 13469.5
If we take 365 away from 430, we end up 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.

Step 8:
If we divide 650 by 73, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 13469.58
The remainder is 66 after subtracting 584 from 650.
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 9:
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: 13469.589
Deduct 657 from 660 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
The number 73 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13469.589
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
300 divided by 73 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13469.58904
Deduct 292 from 300 and we're left with 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 12:
73 can be fit into 80 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 13469.589041
Subtract 73 from 80 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
If we divide 70 by 73, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 13469.589041
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.

Let's proceed to step 14:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 13469.58904109
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 13469.58904109 with a remainder of 4.3e-08.
