We look at the division of 818649 by 93 
The aim is to understand the frequency of 93 in 818649.

Let's proceed to step 1:
When dividing 8 by 93, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 93

Advancing to step 2:
93 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 93

Going ahead to step 3:
93 goes into 818 8 times with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 744 from 818 to get 74.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 93

Let's proceed to step 4:
93 goes into 746 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 88.0
Subtracting 744 from 746 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 93

Let's proceed to step 5:
24 divided by 93 is 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 880.0
Subtract 0 from 24 to get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 93

Moving on to step 6:
93 goes into 249 2 times with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 8802.0
If we subtract 186 from 249, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
93 can be fit into 630 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 8802.6
If we subtract 558 from 630, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
The number 93 fits into 720 7 times, leaving a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 8802.67
If we take 651 away from 720, we end up 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.

On to step 9:
The number 93 fits into 690 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 8802.677
Subtracting 651 from 690 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 8802.677 with a remainder of 0.0039.
