67650012 ÷ 503 
The aim is to understand the frequency of 503 in 67650012.

Step 1:
503 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 503

Step 2:
503 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 503

Advancing to step 3:
676 divided by 503 is 1 with a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 503 from 676, we get 173.
Grab the next digit (5) from the dividend, add it to 173, then carry on: 1735 / 503

Going ahead to step 4:
When dividing 1735 by 503, we get 3 with a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1509 from 1735, we get 226.
Take the next digit (0) from the dividend and append it to 226, then repeat: 2260 / 503

Advancing to step 5:
If we divide 2260 by 503, we get 4 and a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 134.0
Deduct 2012 from 2260 and we're left with 248.
Take the next digit (0) from the dividend and append it to 248, then repeat: 2480 / 503

Going ahead to step 6:
When dividing 2480 by 503, we get 4 with a remainder of 468.
Put 4 as the next digit of the answer. 
Result so far: 1344.0
The remainder is 468 after subtracting 2012 from 2480.
Fetch the next digit (1) from the dividend, attach it to 468 and continue: 4681 / 503

Let's proceed to step 7:
503 goes into 4681 9 times with a remainder of 154.
Write down 9 as next digit of the result. 
Result so far: 13449.0
If we take 4527 away from 4681, we end up with 154.
Grab the next digit (2) from the dividend, add it to 154, then carry on: 1542 / 503

Moving on to step 8:
The number 503 fits into 1542 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 134493.0
Subtracting 1509 from 1542 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
330 divided by 503 is 0 with a remainder of 330.
The next digit of our result is 0. 
Result so far: 134493.0
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
3300 divided by 503 is 6 with a remainder of 282.
The number 6 becomes the next digit in our result. 
Result so far: 134493.06
Deduct 3018 from 3300 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 11:
The number 503 fits into 2820 5 times, leaving a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 134493.065
If we subtract 2515 from 2820, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 12:
If we divide 3050 by 503, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 134493.0656
Deduct 3018 from 3050 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
The number 503 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 134493.0656
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
503 goes into 3200 6 times with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 134493.065606
If we subtract 3018 from 3200, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 15:
1820 divided by 503 is 3 with a remainder of 311.
Write down 3 as next digit of the result. 
Result so far: 134493.0656063
The remainder is 311 after subtracting 1509 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 16:
503 can be fit into 3110 6 times, resulting in a remainder of 92.
The next digit of our result is 6. 
Result so far: 134493.06560636
Deduct 3018 from 3110 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 134493.06560636 with a remainder of 9.2e-08.
