90277760 divided by 504 
The aim is to understand the frequency of 504 in 90277760.

Step 1:
9 divided by 504 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 504

Moving on to step 2:
If we divide 90 by 504, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (2) from the dividend and append it to 90, then repeat: 902 / 504

Step 3:
504 can be fit into 902 1 times, resulting in a remainder of 398.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 504 away from 902, we end up with 398.
Include the next digit (7) from the dividend after 398, then repeat: 3987 / 504

On to step 4:
504 goes into 3987 7 times with a remainder of 459.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 3528 from 3987, we get 459.
Bring next digit (7) of the dividend behind the 459 and repeat the process: 4597 / 504

Going ahead to step 5:
When dividing 4597 by 504, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 179.0
Subtracting 4536 from 4597 leaves us with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 504

Advancing to step 6:
If we divide 617 by 504, we get 1 and a remainder of 113.
Put 1 as the next digit of the answer. 
Result so far: 1791.0
If we take 504 away from 617, we end up with 113.
Append the next digit (6) from the dividend to 113 and continue with: 1136 / 504

Moving on to step 7:
The number 504 fits into 1136 2 times, leaving a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 17912.0
If we subtract 1008 from 1136, we get 128.
Bring next digit (0) of the dividend behind the 128 and repeat the process: 1280 / 504

Step 8:
The number 504 fits into 1280 2 times, leaving a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 179122.0
Deduct 1008 from 1280 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 9:
2720 divided by 504 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 179122.5
If we take 2520 away from 2720, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
2000 divided by 504 is 3 with a remainder of 488.
The number 3 becomes the next digit in our result. 
Result so far: 179122.53
Subtracting 1512 from 2000 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 11:
504 goes into 4880 9 times with a remainder of 344.
Record the quotient 9 as the next digit in the result. 
Result so far: 179122.539
If we take 4536 away from 4880, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 12:
The number 504 fits into 3440 6 times, leaving a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 179122.5396
If we subtract 3024 from 3440, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 13:
504 can be fit into 4160 8 times, resulting in a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 179122.53968
Subtracting 4032 from 4160 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
The number 504 fits into 1280 2 times, leaving a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 179122.539682
If we subtract 1008 from 1280, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 15:
2720 divided by 504 is 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 179122.5396825
Deduct 2520 from 2720 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 16:
2000 divided by 504 is 3 with a remainder of 488.
The next digit of our result is 3. 
Result so far: 179122.53968253
Subtracting 1512 from 2000 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 179122.53968253 with a remainder of 4.88e-07.
