We divide 512557 by 703
The aim is to understand the frequency of 703 in 512557.

Let's proceed to step 1:
5 divided by 703 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 703

Going ahead to step 2:
703 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 703

Going ahead to step 3:
703 can be fit into 512 0 times, resulting in a remainder of 512.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 512 leaves us with 512.
Bring next digit (5) of the dividend behind the 512 and repeat the process: 5125 / 703

Let's proceed to step 4:
When dividing 5125 by 703, we get 7 with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 4921 from 5125 leaves us with 204.
Bring next digit (5) of the dividend behind the 204 and repeat the process: 2045 / 703

Step 5:
The number 703 fits into 2045 2 times, leaving a remainder of 639.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 639 after subtracting 1406 from 2045.
Fetch the next digit (7) from the dividend, attach it to 639 and continue: 6397 / 703

Moving on to step 6:
6397 divided by 703 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 729.0
Deduct 6327 from 6397 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
The number 703 fits into 700 0 times, leaving a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 729.0
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 8:
7000 divided by 703 is 9 with a remainder of 673.
Use 9 as the next digit of our solution. 
Result so far: 729.09
Deduct 6327 from 7000 and we're left with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Going ahead to step 9:
703 can be fit into 6730 9 times, resulting in a remainder of 403.
Put 9 as the next digit of the answer. 
Result so far: 729.099
Subtracting 6327 from 6730 leaves us with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

The final outcome is 729.099, with a leftover of 0.0403.
