We look at the division of 408336 by 73 
The aim is to understand the frequency of 73 in 408336.

Let's proceed to step 1:
4 divided by 73 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 73

Step 2:
When dividing 40 by 73, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 73

Step 3:
408 divided by 73 is 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 365 from 408, we get 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 73

Going ahead to step 4:
The number 73 fits into 433 5 times, leaving a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Deduct 365 from 433 and we're left with 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 73

Moving on to step 5:
If we divide 683 by 73, we get 9 and a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
If we take 657 away from 683, we end up with 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 73

Step 6:
73 can be fit into 266 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 5593.0
The remainder is 47 after subtracting 219 from 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
73 goes into 470 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 5593.6
If we take 438 away from 470, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
73 can be fit into 320 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 5593.64
Subtract 292 from 320 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 73, we get 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 5593.643
The remainder is 61 after subtracting 219 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
If we divide 610 by 73, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 5593.6438
Subtract 584 from 610 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
260 divided by 73 is 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 5593.64383
If we subtract 219 from 260, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
73 goes into 410 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 5593.643835
Subtracting 365 from 410 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
450 divided by 73 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 5593.6438356
If we take 438 away from 450, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
When dividing 120 by 73, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 5593.64383561
Subtracting 73 from 120 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 5593.64383561 with a remainder of 4.7e-08.
