22779280 ÷ 503 
The aim is to understand the frequency of 503 in 22779280.

On to step 1:
If we divide 2 by 503, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 503

Step 2:
The number 503 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 503

Advancing to step 3:
227 divided by 503 is 0 with a remainder of 227.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 227 to get 227.
Bring next digit (7) of the dividend behind the 227 and repeat the process: 2277 / 503

Moving on to step 4:
503 goes into 2277 4 times with a remainder of 265.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2012 away from 2277, we end up with 265.
Grab the next digit (9) from the dividend, add it to 265, then carry on: 2659 / 503

Advancing to step 5:
503 can be fit into 2659 5 times, resulting in a remainder of 144.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 144 after subtracting 2515 from 2659.
Take the next digit (2) from the dividend and append it to 144, then repeat: 1442 / 503

Advancing to step 6:
The number 503 fits into 1442 2 times, leaving a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 452.0
Deduct 1006 from 1442 and we're left with 436.
Take the next digit (8) from the dividend and append it to 436, then repeat: 4368 / 503

Step 7:
503 goes into 4368 8 times with a remainder of 344.
Put 8 as the next digit of the answer. 
Result so far: 4528.0
The remainder is 344 after subtracting 4024 from 4368.
Take the next digit (0) from the dividend and append it to 344, then repeat: 3440 / 503

On to step 8:
3440 divided by 503 is 6 with a remainder of 422.
Record the quotient 6 as the next digit in the result. 
Result so far: 45286.0
If we subtract 3018 from 3440, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 9:
If we divide 4220 by 503, we get 8 and a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 45286.8
Subtract 4024 from 4220 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 10:
When dividing 1960 by 503, we get 3 with a remainder of 451.
Record the quotient 3 as the next digit in the result. 
Result so far: 45286.83
Subtract 1509 from 1960 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 11:
503 goes into 4510 8 times with a remainder of 486.
Put 8 as the next digit of the answer. 
Result so far: 45286.838
Subtracting 4024 from 4510 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 12:
If we divide 4860 by 503, we get 9 and a remainder of 333.
The number 9 becomes the next digit in our result. 
Result so far: 45286.8389
Deduct 4527 from 4860 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 13:
503 can be fit into 3330 6 times, resulting in a remainder of 312.
Put 6 as the next digit of the answer. 
Result so far: 45286.83896
If we subtract 3018 from 3330, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 14:
503 can be fit into 3120 6 times, resulting in a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 45286.838966
Subtracting 3018 from 3120 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 45286.838966, with a leftover of 1.02e-05.
