Let's divide 58900123 by 503
The aim is to understand the frequency of 503 in 58900123.

Let's proceed to step 1:
503 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 503

On to step 2:
If we divide 58 by 503, we get 0 and a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 503

Advancing to step 3:
When dividing 589 by 503, we get 1 with a remainder of 86.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 86 after subtracting 503 from 589.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 503

Moving on to step 4:
503 can be fit into 860 1 times, resulting in a remainder of 357.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 357 after subtracting 503 from 860.
Bring next digit (0) of the dividend behind the 357 and repeat the process: 3570 / 503

Step 5:
503 goes into 3570 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 3521 from 3570 and we're left with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 503

Advancing to step 6:
491 divided by 503 is 0 with a remainder of 491.
Put 0 as the next digit of the answer. 
Result so far: 1170.0
The remainder is 491 after subtracting 0 from 491.
Fetch the next digit (2) from the dividend, attach it to 491 and continue: 4912 / 503

Advancing to step 7:
503 goes into 4912 9 times with a remainder of 385.
Put 9 as the next digit of the answer. 
Result so far: 11709.0
If we take 4527 away from 4912, we end up with 385.
Grab the next digit (3) from the dividend, add it to 385, then carry on: 3853 / 503

Let's proceed to step 8:
When dividing 3853 by 503, we get 7 with a remainder of 332.
Record the quotient 7 as the next digit in the result. 
Result so far: 117097.0
Deduct 3521 from 3853 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 9:
503 goes into 3320 6 times with a remainder of 302.
Record the quotient 6 as the next digit in the result. 
Result so far: 117097.6
If we subtract 3018 from 3320, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 10:
503 can be fit into 3020 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 117097.66
Deduct 3018 from 3020 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 117097.66 and a remainder of 0.002.
