We divide 393985 by 73
The aim is to understand the frequency of 73 in 393985.

Moving on to step 1:
If we divide 3 by 73, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 73

Step 2:
39 divided by 73 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 73

Let's proceed to step 3:
393 divided by 73 is 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 5.0
If we take 365 away from 393, we end up with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 73

Step 4:
73 goes into 289 3 times with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we subtract 219 from 289, we get 70.
Fetch the next digit (8) from the dividend, attach it to 70 and continue: 708 / 73

Step 5:
When dividing 708 by 73, we get 9 with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 539.0
If we take 657 away from 708, we end up with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 73

Moving on to step 6:
The number 73 fits into 515 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 5397.0
Deduct 511 from 515 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
73 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5397.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
The number 73 fits into 400 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5397.05
Deduct 365 from 400 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
When dividing 350 by 73, we get 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 5397.054
Subtracting 292 from 350 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
73 goes into 580 7 times with a remainder of 69.
The next digit of our result is 7. 
Result so far: 5397.0547
Deduct 511 from 580 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 11:
690 divided by 73 is 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 5397.05479
Subtracting 657 from 690 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
330 divided by 73 is 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 5397.054794
If we subtract 292 from 330, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
If we divide 380 by 73, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5397.0547945
If we subtract 365 from 380, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
When dividing 150 by 73, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5397.05479452
If we subtract 146 from 150, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 5397.05479452, with a leftover of 4e-09.
