We look at the division of 13977424 by 597 
The aim is to understand the frequency of 597 in 13977424.

Let's proceed to step 1:
1 divided by 597 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 597

Step 2:
The number 597 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 597

On to step 3:
The number 597 fits into 139 0 times, leaving a remainder of 139.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 139 to get 139.
Include the next digit (7) from the dividend after 139, then repeat: 1397 / 597

Step 4:
597 goes into 1397 2 times with a remainder of 203.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1194 from 1397 leaves us with 203.
Append the next digit (7) from the dividend to 203 and continue with: 2037 / 597

Moving on to step 5:
When dividing 2037 by 597, we get 3 with a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 246 after subtracting 1791 from 2037.
Include the next digit (4) from the dividend after 246, then repeat: 2464 / 597

On to step 6:
If we divide 2464 by 597, we get 4 and a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Subtracting 2388 from 2464 leaves us with 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 597

Going ahead to step 7:
762 divided by 597 is 1 with a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 2341.0
Deduct 597 from 762 and we're left with 165.
Fetch the next digit (4) from the dividend, attach it to 165 and continue: 1654 / 597

Moving on to step 8:
597 goes into 1654 2 times with a remainder of 460.
Use 2 as the next digit of our solution. 
Result so far: 23412.0
The remainder is 460 after subtracting 1194 from 1654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 9:
The number 597 fits into 4600 7 times, leaving a remainder of 421.
The next digit of our result is 7. 
Result so far: 23412.7
Deduct 4179 from 4600 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 10:
When dividing 4210 by 597, we get 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 23412.77
Deduct 4179 from 4210 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 23412.77 with a remainder of 0.031.
