We look at the division of 5996307 by 993 
The aim is to understand the frequency of 993 in 5996307.

Going ahead to step 1:
When dividing 5 by 993, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 993

Going ahead to step 2:
The number 993 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 993

Advancing to step 3:
When dividing 599 by 993, we get 0 with a remainder of 599.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 599 and we're left with 599.
Take the next digit (6) from the dividend and append it to 599, then repeat: 5996 / 993

Going ahead to step 4:
993 goes into 5996 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 5958 from 5996 to get 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 993

Moving on to step 5:
993 can be fit into 383 0 times, resulting in a remainder of 383.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we take 0 away from 383, we end up with 383.
Bring next digit (0) of the dividend behind the 383 and repeat the process: 3830 / 993

Step 6:
The number 993 fits into 3830 3 times, leaving a remainder of 851.
Write down 3 as next digit of the result. 
Result so far: 603.0
Deduct 2979 from 3830 and we're left with 851.
Include the next digit (7) from the dividend after 851, then repeat: 8517 / 993

Moving on to step 7:
8517 divided by 993 is 8 with a remainder of 573.
Write down 8 as next digit of the result. 
Result so far: 6038.0
Subtract 7944 from 8517 to get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 8:
The number 993 fits into 5730 5 times, leaving a remainder of 765.
The next digit of our result is 5. 
Result so far: 6038.5
Deduct 4965 from 5730 and we're left with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Moving on to step 9:
7650 divided by 993 is 7 with a remainder of 699.
The number 7 becomes the next digit in our result. 
Result so far: 6038.57
Subtracting 6951 from 7650 leaves us with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Moving on to step 10:
6990 divided by 993 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 6038.577
Deduct 6951 from 6990 and we're left 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.

After the division, we end up with 6038.577 and a remainder of 0.0039.
