We look at the division of 644422 by 93 
The aim is to understand the frequency of 93 in 644422.

Step 1:
If we divide 6 by 93, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 93

Let's proceed to step 2:
The number 93 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 93

Step 3:
When dividing 644 by 93, we get 6 with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 558 from 644 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 93

Step 4:
93 can be fit into 864 9 times, resulting in a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Deduct 837 from 864 and we're left with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 93

Moving on to step 5:
When dividing 272 by 93, we get 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 692.0
Subtracting 186 from 272 leaves us with 86.
Grab the next digit (2) from the dividend, add it to 86, then carry on: 862 / 93

On to step 6:
93 goes into 862 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 6929.0
Deduct 837 from 862 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
If we divide 250 by 93, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 6929.2
Subtracting 186 from 250 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
93 goes into 640 6 times with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 6929.26
Subtracting 558 from 640 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
When dividing 820 by 93, we get 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 6929.268
Subtract 744 from 820 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
If we divide 760 by 93, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 6929.2688
The remainder is 16 after subtracting 744 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 6929.2688 and a remainder of 0.00016.
