We look at the division of 35143693 by 393 
The aim is to understand the frequency of 393 in 35143693.

Going ahead to step 1:
If we divide 3 by 393, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 393

Advancing to step 2:
393 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 393

Step 3:
393 goes into 351 0 times with a remainder of 351.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 351 leaves us with 351.
Grab the next digit (4) from the dividend, add it to 351, then carry on: 3514 / 393

Let's proceed to step 4:
If we divide 3514 by 393, we get 8 and a remainder of 370.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 370 after subtracting 3144 from 3514.
Bring next digit (3) of the dividend behind the 370 and repeat the process: 3703 / 393

Moving on to step 5:
393 goes into 3703 9 times with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we take 3537 away from 3703, we end up with 166.
Bring next digit (6) of the dividend behind the 166 and repeat the process: 1666 / 393

On to step 6:
The number 393 fits into 1666 4 times, leaving a remainder of 94.
The next digit of our result is 4. 
Result so far: 894.0
Subtracting 1572 from 1666 leaves us with 94.
Take the next digit (9) from the dividend and append it to 94, then repeat: 949 / 393

Going ahead to step 7:
393 can be fit into 949 2 times, resulting in a remainder of 163.
The next digit of our result is 2. 
Result so far: 8942.0
If we take 786 away from 949, we end up with 163.
Fetch the next digit (3) from the dividend, attach it to 163 and continue: 1633 / 393

Moving on to step 8:
When dividing 1633 by 393, we get 4 with a remainder of 61.
Put 4 as the next digit of the answer. 
Result so far: 89424.0
If we subtract 1572 from 1633, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
393 can be fit into 610 1 times, resulting in a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 89424.1
If we subtract 393 from 610, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 10:
When dividing 2170 by 393, we get 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 89424.15
Deduct 1965 from 2170 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 11:
When dividing 2050 by 393, we get 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 89424.155
Subtracting 1965 from 2050 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 89424.155 and a remainder of 0.0085.
