20313390 ÷ 503 
The aim is to understand the frequency of 503 in 20313390.

Moving on to step 1:
503 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 503

Going ahead to step 2:
When dividing 20 by 503, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 503

Step 3:
503 goes into 203 0 times with a remainder of 203.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Bring next digit (1) of the dividend behind the 203 and repeat the process: 2031 / 503

Let's proceed to step 4:
If we divide 2031 by 503, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2012 from 2031 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 503

Let's proceed to step 5:
When dividing 193 by 503, we get 0 with a remainder of 193.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 193, we get 193.
Fetch the next digit (3) from the dividend, attach it to 193 and continue: 1933 / 503

Advancing to step 6:
503 can be fit into 1933 3 times, resulting in a remainder of 424.
Write down 3 as next digit of the result. 
Result so far: 403.0
Subtract 1509 from 1933 to get 424.
Append the next digit (9) from the dividend to 424 and continue with: 4249 / 503

Going ahead to step 7:
When dividing 4249 by 503, we get 8 with a remainder of 225.
The next digit of our result is 8. 
Result so far: 4038.0
If we take 4024 away from 4249, we end up with 225.
Grab the next digit (0) from the dividend, add it to 225, then carry on: 2250 / 503

Moving on to step 8:
If we divide 2250 by 503, we get 4 and a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 40384.0
Deduct 2012 from 2250 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.

Step 9:
2380 divided by 503 is 4 with a remainder of 368.
The next digit of our result is 4. 
Result so far: 40384.4
If we take 2012 away from 2380, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 10:
The number 503 fits into 3680 7 times, leaving a remainder of 159.
The number 7 becomes the next digit in our result. 
Result so far: 40384.47
Subtracting 3521 from 3680 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 11:
The number 503 fits into 1590 3 times, leaving a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 40384.473
If we subtract 1509 from 1590, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 12:
When dividing 810 by 503, we get 1 with a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 40384.4731
Subtract 503 from 810 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Advancing to step 13:
503 can be fit into 3070 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 40384.47316
Subtracting 3018 from 3070 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
The number 503 fits into 520 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 40384.473161
If we take 503 away from 520, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 15:
The number 503 fits into 170 0 times, leaving a remainder of 170.
The next digit of our result is 0. 
Result so far: 40384.473161
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 16:
The number 503 fits into 1700 3 times, leaving a remainder of 191.
The next digit of our result is 3. 
Result so far: 40384.47316103
If we subtract 1509 from 1700, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The quotient of the division is 40384.47316103, and the remainder is 1.91e-07.
