85764633 divided by 503 
The aim is to understand the frequency of 503 in 85764633.

Let's proceed to step 1:
8 divided by 503 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 503

Step 2:
If we divide 85 by 503, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 503

Let's proceed to step 3:
503 goes into 857 1 times with a remainder of 354.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 503 from 857 and we're left with 354.
Take the next digit (6) from the dividend and append it to 354, then repeat: 3546 / 503

Moving on to step 4:
When dividing 3546 by 503, we get 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 17.0
If we take 3521 away from 3546, we end up with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 503

Moving on to step 5:
254 divided by 503 is 0 with a remainder of 254.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtract 0 from 254 to get 254.
Fetch the next digit (6) from the dividend, attach it to 254 and continue: 2546 / 503

Step 6:
The number 503 fits into 2546 5 times, leaving a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 1705.0
If we take 2515 away from 2546, we end up with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 503

On to step 7:
313 divided by 503 is 0 with a remainder of 313.
Put 0 as the next digit of the answer. 
Result so far: 17050.0
If we take 0 away from 313, we end up with 313.
Take the next digit (3) from the dividend and append it to 313, then repeat: 3133 / 503

Let's proceed to step 8:
The number 503 fits into 3133 6 times, leaving a remainder of 115.
Write down 6 as next digit of the result. 
Result so far: 170506.0
If we take 3018 away from 3133, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 9:
If we divide 1150 by 503, we get 2 and a remainder of 144.
Use 2 as the next digit of our solution. 
Result so far: 170506.2
Subtract 1006 from 1150 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 10:
The number 503 fits into 1440 2 times, leaving a remainder of 434.
Record the quotient 2 as the next digit in the result. 
Result so far: 170506.22
If we take 1006 away from 1440, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

After the division, we end up with 170506.22 and a remainder of 0.434.
