Let's divide 90277508 by 993
The aim is to understand the frequency of 993 in 90277508.

Going ahead to step 1:
9 divided by 993 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 993

Going ahead to step 2:
If we divide 90 by 993, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 993

Let's proceed to step 3:
The number 993 fits into 902 0 times, leaving a remainder of 902.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 902 leaves us with 902.
Include the next digit (7) from the dividend after 902, then repeat: 9027 / 993

Let's proceed to step 4:
When dividing 9027 by 993, we get 9 with a remainder of 90.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 8937 from 9027, we get 90.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 993

Going ahead to step 5:
If we divide 907 by 993, we get 0 and a remainder of 907.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 907, we end up with 907.
Append the next digit (5) from the dividend to 907 and continue with: 9075 / 993

On to step 6:
993 can be fit into 9075 9 times, resulting in a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 909.0
The remainder is 138 after subtracting 8937 from 9075.
Include the next digit (0) from the dividend after 138, then repeat: 1380 / 993

Advancing to step 7:
When dividing 1380 by 993, we get 1 with a remainder of 387.
The number 1 becomes the next digit in our result. 
Result so far: 9091.0
Deduct 993 from 1380 and we're left with 387.
Append the next digit (8) from the dividend to 387 and continue with: 3878 / 993

Moving on to step 8:
If we divide 3878 by 993, we get 3 and a remainder of 899.
Write down 3 as next digit of the result. 
Result so far: 90913.0
Subtract 2979 from 3878 to get 899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8990, and continue the process.

Advancing to step 9:
If we divide 8990 by 993, we get 9 and a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 90913.9
If we subtract 8937 from 8990, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 10:
993 can be fit into 530 0 times, resulting in a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 90913.9
The remainder is 530 after subtracting 0 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 11:
5300 divided by 993 is 5 with a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 90913.905
If we subtract 4965 from 5300, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 12:
3350 divided by 993 is 3 with a remainder of 371.
The number 3 becomes the next digit in our result. 
Result so far: 90913.9053
If we take 2979 away from 3350, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 13:
When dividing 3710 by 993, we get 3 with a remainder of 731.
Record the quotient 3 as the next digit in the result. 
Result so far: 90913.90533
Subtracting 2979 from 3710 leaves us with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

The final outcome is 90913.90533, with a leftover of 0.000731.
