76593735 divided by 503 
The aim is to understand the frequency of 503 in 76593735.

Going ahead to step 1:
7 divided by 503 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 503

Going ahead to step 2:
503 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 503

Let's proceed to step 3:
When dividing 765 by 503, we get 1 with a remainder of 262.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 503 from 765 and we're left with 262.
Fetch the next digit (9) from the dividend, attach it to 262 and continue: 2629 / 503

Moving on to step 4:
When dividing 2629 by 503, we get 5 with a remainder of 114.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 2515 from 2629 leaves us with 114.
Bring next digit (3) of the dividend behind the 114 and repeat the process: 1143 / 503

Step 5:
When dividing 1143 by 503, we get 2 with a remainder of 137.
The next digit of our result is 2. 
Result so far: 152.0
If we take 1006 away from 1143, we end up with 137.
Grab the next digit (7) from the dividend, add it to 137, then carry on: 1377 / 503

Advancing to step 6:
503 goes into 1377 2 times with a remainder of 371.
Record the quotient 2 as the next digit in the result. 
Result so far: 1522.0
Subtract 1006 from 1377 to get 371.
Grab the next digit (3) from the dividend, add it to 371, then carry on: 3713 / 503

Advancing to step 7:
503 goes into 3713 7 times with a remainder of 192.
The number 7 becomes the next digit in our result. 
Result so far: 15227.0
If we subtract 3521 from 3713, we get 192.
Append the next digit (5) from the dividend to 192 and continue with: 1925 / 503

Advancing to step 8:
503 can be fit into 1925 3 times, resulting in a remainder of 416.
Write down 3 as next digit of the result. 
Result so far: 152273.0
Subtracting 1509 from 1925 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 9:
When dividing 4160 by 503, we get 8 with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 152273.8
Deduct 4024 from 4160 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
If we divide 1360 by 503, we get 2 and a remainder of 354.
Use 2 as the next digit of our solution. 
Result so far: 152273.82
If we subtract 1006 from 1360, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 11:
503 goes into 3540 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 152273.827
If we subtract 3521 from 3540, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
The number 503 fits into 190 0 times, leaving a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 152273.827
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 13:
The number 503 fits into 1900 3 times, leaving a remainder of 391.
Use 3 as the next digit of our solution. 
Result so far: 152273.82703
If we subtract 1509 from 1900, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 14:
3910 divided by 503 is 7 with a remainder of 389.
Write down 7 as next digit of the result. 
Result so far: 152273.827037
The remainder is 389 after subtracting 3521 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 15:
If we divide 3890 by 503, we get 7 and a remainder of 369.
The number 7 becomes the next digit in our result. 
Result so far: 152273.8270377
Subtract 3521 from 3890 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

The final outcome is 152273.8270377, with a leftover of 3.69e-06.
