4924980 ÷ 997 
The aim is to understand the frequency of 997 in 4924980.

Going ahead to step 1:
If we divide 4 by 997, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 997

Moving on to step 2:
997 goes into 49 0 times with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 997

Advancing to step 3:
997 can be fit into 492 0 times, resulting in a remainder of 492.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 492 to get 492.
Grab the next digit (4) from the dividend, add it to 492, then carry on: 4924 / 997

Advancing to step 4:
When dividing 4924 by 997, we get 4 with a remainder of 936.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3988 from 4924 to get 936.
Grab the next digit (9) from the dividend, add it to 936, then carry on: 9369 / 997

Let's proceed to step 5:
9369 divided by 997 is 9 with a remainder of 396.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 8973 from 9369, we get 396.
Fetch the next digit (8) from the dividend, attach it to 396 and continue: 3968 / 997

Let's proceed to step 6:
3968 divided by 997 is 3 with a remainder of 977.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
The remainder is 977 after subtracting 2991 from 3968.
Include the next digit (0) from the dividend after 977, then repeat: 9770 / 997

Step 7:
If we divide 9770 by 997, we get 9 and a remainder of 797.
The number 9 becomes the next digit in our result. 
Result so far: 4939.0
Subtracting 8973 from 9770 leaves us with 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Moving on to step 8:
The number 997 fits into 7970 7 times, leaving a remainder of 991.
Record the quotient 7 as the next digit in the result. 
Result so far: 4939.7
If we take 6979 away from 7970, we end up with 991.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9910, and continue the process.

Step 9:
997 goes into 9910 9 times with a remainder of 937.
Use 9 as the next digit of our solution. 
Result so far: 4939.79
If we subtract 8973 from 9910, we get 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

Going ahead to step 10:
If we divide 9370 by 997, we get 9 and a remainder of 397.
Use 9 as the next digit of our solution. 
Result so far: 4939.799
Subtracting 8973 from 9370 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

The final outcome is 4939.799, with a leftover of 0.0397.
