We look at the division of 980251 by 73 
The aim is to understand the frequency of 73 in 980251.

On to step 1:
73 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 73

Moving on to step 2:
73 can be fit into 98 1 times, resulting in a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 73 from 98 and we're left with 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 73

Step 3:
When dividing 250 by 73, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 13.0
If we take 219 away from 250, we end up with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 73

Going ahead to step 4:
When dividing 312 by 73, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 292 from 312 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 73

Moving on to step 5:
205 divided by 73 is 2 with a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 1342.0
If we subtract 146 from 205, we get 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 73

Advancing to step 6:
The number 73 fits into 591 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 13428.0
If we take 584 away from 591, we end up 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.

Going ahead to step 7:
73 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 13428.0
If we subtract 0 from 70, we 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 8:
When dividing 700 by 73, we get 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 13428.09
If we take 657 away from 700, we end up 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.

Step 9:
73 can be fit into 430 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 13428.095
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.

Let's proceed to step 10:
When dividing 650 by 73, we get 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 13428.0958
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.

Let's proceed to step 11:
The number 73 fits into 660 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 13428.09589
If we subtract 657 from 660, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
The number 73 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 13428.09589
The remainder is 30 after subtracting 0 from 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 13:
300 divided by 73 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13428.0958904
If we take 292 away from 300, we end up 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.

Moving on to step 14:
If we divide 80 by 73, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 13428.09589041
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.

The final outcome is 13428.09589041, with a leftover of 7e-09.
