We look at the division of 918633 by 93 
The aim is to understand the frequency of 93 in 918633.

Step 1:
93 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 93

Advancing to step 2:
91 divided by 93 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 93

Going ahead to step 3:
If we divide 918 by 93, we get 9 and a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 837 away from 918, we end up with 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 93

Let's proceed to step 4:
93 can be fit into 816 8 times, resulting in a remainder of 72.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 744 from 816 leaves us with 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 93

Going ahead to step 5:
The number 93 fits into 723 7 times, leaving a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
The remainder is 72 after subtracting 651 from 723.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 93

Moving on to step 6:
93 goes into 723 7 times with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 9877.0
The remainder is 72 after subtracting 651 from 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 7:
93 can be fit into 720 7 times, resulting in a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 9877.7
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.

Advancing to step 8:
690 divided by 93 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 9877.77
Subtract 651 from 690 to get 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 outcome is 9877.77, with a leftover of 0.039.
