We look at the division of 4938303 by 997 
The aim is to understand the frequency of 997 in 4938303.

Moving on to step 1:
997 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 997

Step 2:
If we divide 49 by 997, we get 0 and a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Append the next digit (3) from the dividend to 49 and continue with: 493 / 997

Step 3:
The number 997 fits into 493 0 times, leaving a remainder of 493.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 493, we get 493.
Grab the next digit (8) from the dividend, add it to 493, then carry on: 4938 / 997

Step 4:
The number 997 fits into 4938 4 times, leaving a remainder of 950.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3988 from 4938 leaves us with 950.
Append the next digit (3) from the dividend to 950 and continue with: 9503 / 997

Advancing to step 5:
9503 divided by 997 is 9 with a remainder of 530.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 8973 from 9503 and we're left with 530.
Grab the next digit (0) from the dividend, add it to 530, then carry on: 5300 / 997

Moving on to step 6:
The number 997 fits into 5300 5 times, leaving a remainder of 315.
The next digit of our result is 5. 
Result so far: 495.0
Subtract 4985 from 5300 to get 315.
Include the next digit (3) from the dividend after 315, then repeat: 3153 / 997

On to step 7:
997 goes into 3153 3 times with a remainder of 162.
The number 3 becomes the next digit in our result. 
Result so far: 4953.0
If we subtract 2991 from 3153, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 8:
If we divide 1620 by 997, we get 1 and a remainder of 623.
The next digit of our result is 1. 
Result so far: 4953.1
If we subtract 997 from 1620, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

On to step 9:
997 goes into 6230 6 times with a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 4953.16
Subtracting 5982 from 6230 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 10:
When dividing 2480 by 997, we get 2 with a remainder of 486.
The number 2 becomes the next digit in our result. 
Result so far: 4953.162
Subtract 1994 from 2480 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 11:
The number 997 fits into 4860 4 times, leaving a remainder of 872.
Write down 4 as next digit of the result. 
Result so far: 4953.1624
If we subtract 3988 from 4860, we get 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Let's proceed to step 12:
997 can be fit into 8720 8 times, resulting in a remainder of 744.
Record the quotient 8 as the next digit in the result. 
Result so far: 4953.16248
The remainder is 744 after subtracting 7976 from 8720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 13:
When dividing 7440 by 997, we get 7 with a remainder of 461.
Use 7 as the next digit of our solution. 
Result so far: 4953.162487
Deduct 6979 from 7440 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 14:
997 can be fit into 4610 4 times, resulting in a remainder of 622.
The next digit of our result is 4. 
Result so far: 4953.1624874
The remainder is 622 after subtracting 3988 from 4610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 15:
997 can be fit into 6220 6 times, resulting in a remainder of 238.
The number 6 becomes the next digit in our result. 
Result so far: 4953.16248746
Deduct 5982 from 6220 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The final outcome is 4953.16248746, with a leftover of 2.38e-07.
