We look at the division of 73069792 by 393 
The aim is to understand the frequency of 393 in 73069792.

Step 1:
393 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 393

Moving on to step 2:
If we divide 73 by 393, we get 0 and a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 393

Let's proceed to step 3:
When dividing 730 by 393, we get 1 with a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 393 from 730 and we're left with 337.
Grab the next digit (6) from the dividend, add it to 337, then carry on: 3376 / 393

Let's proceed to step 4:
When dividing 3376 by 393, we get 8 with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3144 from 3376 leaves us with 232.
Append the next digit (9) from the dividend to 232 and continue with: 2329 / 393

Step 5:
393 goes into 2329 5 times with a remainder of 364.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we subtract 1965 from 2329, we get 364.
Append the next digit (7) from the dividend to 364 and continue with: 3647 / 393

Moving on to step 6:
3647 divided by 393 is 9 with a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 1859.0
Deduct 3537 from 3647 and we're left with 110.
Include the next digit (9) from the dividend after 110, then repeat: 1109 / 393

Advancing to step 7:
The number 393 fits into 1109 2 times, leaving a remainder of 323.
Write down 2 as next digit of the result. 
Result so far: 18592.0
Deduct 786 from 1109 and we're left with 323.
Fetch the next digit (2) from the dividend, attach it to 323 and continue: 3232 / 393

Going ahead to step 8:
3232 divided by 393 is 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 185928.0
Subtracting 3144 from 3232 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
393 can be fit into 880 2 times, resulting in a remainder of 94.
Put 2 as the next digit of the answer. 
Result so far: 185928.2
If we subtract 786 from 880, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
393 goes into 940 2 times with a remainder of 154.
Record the quotient 2 as the next digit in the result. 
Result so far: 185928.22
Subtract 786 from 940 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Our division results in 185928.22 with a remaining 0.154.
