We look at the division of 170250 by 73 
The aim is to understand the frequency of 73 in 170250.

Going ahead to step 1:
The number 73 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 73

On to step 2:
If we divide 17 by 73, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 73

Going ahead to step 3:
The number 73 fits into 170 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 24 after subtracting 146 from 170.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 73

Advancing to step 4:
The number 73 fits into 242 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 23 after subtracting 219 from 242.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 73

Step 5:
73 goes into 235 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 233.0
Subtracting 219 from 235 leaves us with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 73

Let's proceed to step 6:
73 can be fit into 160 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 2332.0
If we take 146 away from 160, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
The number 73 fits into 140 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 2332.1
Subtract 73 from 140 to 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.

Going ahead to step 8:
670 divided by 73 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 2332.19
Subtracting 657 from 670 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
When dividing 130 by 73, we get 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 2332.191
The remainder is 57 after subtracting 73 from 130.
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 10:
The number 73 fits into 570 7 times, leaving a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 2332.1917
Deduct 511 from 570 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
590 divided by 73 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 2332.19178
If we subtract 584 from 590, we get 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 12:
73 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2332.19178
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.

On to step 13:
73 goes into 600 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2332.1917808
Subtract 584 from 600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
73 goes into 160 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2332.19178082
Subtracting 146 from 160 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 2332.19178082 with a remainder of 1.4e-08.
