We look at the division of 227603 by 73 
The aim is to understand the frequency of 73 in 227603.

Going ahead to step 1:
2 divided by 73 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 73

Step 2:
When dividing 22 by 73, we get 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 73

On to step 3:
227 divided by 73 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 219 from 227, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 73

Advancing to step 4:
When dividing 86 by 73, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 73 from 86 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 73

Let's proceed to step 5:
73 goes into 130 1 times with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
Subtract 73 from 130 to get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 73

On to step 6:
73 goes into 573 7 times with a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 3117.0
Deduct 511 from 573 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
73 can be fit into 620 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 3117.8
If we subtract 584 from 620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 73 fits into 360 4 times, leaving a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 3117.84
Subtracting 292 from 360 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
680 divided by 73 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 3117.849
The remainder is 23 after subtracting 657 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
If we divide 230 by 73, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3117.8493
If we take 219 away from 230, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
If we divide 110 by 73, we get 1 and a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 3117.84931
If we take 73 away from 110, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
If we divide 370 by 73, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3117.849315
The remainder is 5 after subtracting 365 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
50 divided by 73 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 3117.849315
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
If we divide 500 by 73, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 3117.84931506
The remainder is 62 after subtracting 438 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 3117.84931506 with a remainder of 6.2e-08.
