We look at the division of 390209 by 93 
The aim is to understand the frequency of 93 in 390209.

Step 1:
93 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 93

Let's proceed to step 2:
93 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 93

Moving on to step 3:
93 goes into 390 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 372 from 390 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 93

Advancing to step 4:
182 divided by 93 is 1 with a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 89 after subtracting 93 from 182.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 93

Moving on to step 5:
890 divided by 93 is 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 419.0
Subtracting 837 from 890 leaves us with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 93

On to step 6:
If we divide 539 by 93, we get 5 and a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 4195.0
The remainder is 74 after subtracting 465 from 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
93 goes into 740 7 times with a remainder of 89.
The next digit of our result is 7. 
Result so far: 4195.7
The remainder is 89 after subtracting 651 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 8:
93 can be fit into 890 9 times, resulting in a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 4195.79
The remainder is 53 after subtracting 837 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
93 can be fit into 530 5 times, resulting in a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 4195.795
Subtract 465 from 530 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
The number 93 fits into 650 6 times, leaving a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 4195.7956
If we take 558 away from 650, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
920 divided by 93 is 9 with a remainder of 83.
Use 9 as the next digit of our solution. 
Result so far: 4195.79569
If we subtract 837 from 920, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
830 divided by 93 is 8 with a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 4195.795698
If we subtract 744 from 830, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 13:
860 divided by 93 is 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 4195.7956989
If we subtract 837 from 860, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
93 goes into 230 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 4195.79569892
The remainder is 44 after subtracting 186 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 4195.79569892 with a balance of 4.4e-08.
