We look at the division of 98398 by 73 
The aim is to understand the frequency of 73 in 98398.

On to step 1:
When dividing 9 by 73, we get 0 with 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

Step 2:
73 goes into 98 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 73 from 98 and we're left with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 73

Advancing to step 3:
253 divided by 73 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 219 away from 253, we end up with 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 73

On to step 4:
If we divide 349 by 73, we get 4 and a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 134.0
If we subtract 292 from 349, we get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 73

On to step 5:
73 can be fit into 578 7 times, resulting in a remainder of 67.
The next digit of our result is 7. 
Result so far: 1347.0
If we subtract 511 from 578, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 6:
73 can be fit into 670 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1347.9
The remainder is 13 after subtracting 657 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 73 is 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 1347.91
If we take 73 away from 130, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 8:
73 goes into 570 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 1347.917
The remainder is 59 after subtracting 511 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
73 goes into 590 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 1347.9178
If we take 584 away from 590, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 73 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1347.9178
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 73 fits into 600 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1347.917808
The remainder is 16 after subtracting 584 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
73 can be fit into 160 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 1347.9178082
The remainder is 14 after subtracting 146 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
73 can be fit into 140 1 times, resulting in a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 1347.91780821
If we take 73 away from 140, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 1347.91780821, with a leftover of 6.7e-08.
