We divide 10878433 by 503
The aim is to understand the frequency of 503 in 10878433.

Moving on to step 1:
503 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 503

On to step 2:
10 divided by 503 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 503

Step 3:
When dividing 108 by 503, we get 0 with a remainder of 108.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 108 leaves us with 108.
Include the next digit (7) from the dividend after 108, then repeat: 1087 / 503

On to step 4:
503 goes into 1087 2 times with a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1006 from 1087 and we're left with 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 503

On to step 5:
818 divided by 503 is 1 with a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 503 from 818 and we're left with 315.
Fetch the next digit (4) from the dividend, attach it to 315 and continue: 3154 / 503

Advancing to step 6:
If we divide 3154 by 503, we get 6 and a remainder of 136.
The next digit of our result is 6. 
Result so far: 216.0
If we subtract 3018 from 3154, we get 136.
Fetch the next digit (3) from the dividend, attach it to 136 and continue: 1363 / 503

Let's proceed to step 7:
503 goes into 1363 2 times with a remainder of 357.
The next digit of our result is 2. 
Result so far: 2162.0
Subtract 1006 from 1363 to get 357.
Include the next digit (3) from the dividend after 357, then repeat: 3573 / 503

Moving on to step 8:
503 can be fit into 3573 7 times, resulting in a remainder of 52.
The next digit of our result is 7. 
Result so far: 21627.0
If we take 3521 away from 3573, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
503 can be fit into 520 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 21627.1
Deduct 503 from 520 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
When dividing 170 by 503, we get 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 21627.1
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
The number 503 fits into 1700 3 times, leaving a remainder of 191.
The next digit of our result is 3. 
Result so far: 21627.103
If we take 1509 away from 1700, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 12:
503 can be fit into 1910 3 times, resulting in a remainder of 401.
The next digit of our result is 3. 
Result so far: 21627.1033
Deduct 1509 from 1910 and we're left with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

The quotient of the division is 21627.1033, and the remainder is 0.00401.
