We're dividing 83076518 by 503 
The aim is to understand the frequency of 503 in 83076518.

Going ahead to step 1:
When dividing 8 by 503, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 503

Advancing to step 2:
503 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 503

Let's proceed to step 3:
503 goes into 830 1 times with a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 503 from 830, we get 327.
Append the next digit (7) from the dividend to 327 and continue with: 3277 / 503

Step 4:
503 can be fit into 3277 6 times, resulting in a remainder of 259.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 3018 from 3277 to get 259.
Bring next digit (6) of the dividend behind the 259 and repeat the process: 2596 / 503

Advancing to step 5:
503 goes into 2596 5 times with a remainder of 81.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 2515 from 2596 to get 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 503

Going ahead to step 6:
If we divide 815 by 503, we get 1 and a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 1651.0
If we take 503 away from 815, we end up with 312.
Take the next digit (1) from the dividend and append it to 312, then repeat: 3121 / 503

Advancing to step 7:
If we divide 3121 by 503, we get 6 and a remainder of 103.
Record the quotient 6 as the next digit in the result. 
Result so far: 16516.0
Subtract 3018 from 3121 to get 103.
Take the next digit (8) from the dividend and append it to 103, then repeat: 1038 / 503

Advancing to step 8:
503 goes into 1038 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 165162.0
Subtracting 1006 from 1038 leaves us 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.

Advancing to step 9:
If we divide 320 by 503, we get 0 and a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 165162.0
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
The number 503 fits into 3200 6 times, leaving a remainder of 182.
Put 6 as the next digit of the answer. 
Result so far: 165162.06
Subtract 3018 from 3200 to 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.

Going ahead to step 11:
1820 divided by 503 is 3 with a remainder of 311.
The next digit of our result is 3. 
Result so far: 165162.063
If we subtract 1509 from 1820, we get 311.
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 12:
When dividing 3110 by 503, we get 6 with a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 165162.0636
Subtracting 3018 from 3110 leaves us 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.

Advancing to step 13:
The number 503 fits into 920 1 times, leaving a remainder of 417.
The next digit of our result is 1. 
Result so far: 165162.06361
The remainder is 417 after subtracting 503 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 14:
If we divide 4170 by 503, we get 8 and a remainder of 146.
The number 8 becomes the next digit in our result. 
Result so far: 165162.063618
If we subtract 4024 from 4170, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 15:
503 can be fit into 1460 2 times, resulting in a remainder of 454.
Use 2 as the next digit of our solution. 
Result so far: 165162.0636182
The remainder is 454 after subtracting 1006 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 16:
When dividing 4540 by 503, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 165162.06361829
Deduct 4527 from 4540 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 165162.06361829 with a remaining 1.3e-08.
