Let's divide 3378810 by 503
We want to figure out the number of times 3378810 can be divided by 503.

On to step 1:
The number 503 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 503

On to step 2:
When dividing 33 by 503, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 503

Step 3:
The number 503 fits into 337 0 times, leaving a remainder of 337.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 337 leaves us with 337.
Append the next digit (8) from the dividend to 337 and continue with: 3378 / 503

Step 4:
3378 divided by 503 is 6 with a remainder of 360.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 3018 from 3378 and we're left with 360.
Take the next digit (8) from the dividend and append it to 360, then repeat: 3608 / 503

On to step 5:
When dividing 3608 by 503, we get 7 with a remainder of 87.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 3521 from 3608 and we're left with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 503

Advancing to step 6:
503 goes into 871 1 times with a remainder of 368.
Use 1 as the next digit of our solution. 
Result so far: 671.0
If we take 503 away from 871, we end up with 368.
Take the next digit (0) from the dividend and append it to 368, then repeat: 3680 / 503

Let's proceed to step 7:
503 can be fit into 3680 7 times, resulting in a remainder of 159.
The next digit of our result is 7. 
Result so far: 6717.0
If we take 3521 away from 3680, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 8:
1590 divided by 503 is 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 6717.3
Subtracting 1509 from 1590 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
If we divide 810 by 503, we get 1 and a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 6717.31
The remainder is 307 after subtracting 503 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 10:
When dividing 3070 by 503, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 6717.316
The remainder is 52 after subtracting 3018 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
If we divide 520 by 503, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 6717.3161
Subtract 503 from 520 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
The number 503 fits into 170 0 times, leaving a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 6717.3161
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 13:
1700 divided by 503 is 3 with a remainder of 191.
Record the quotient 3 as the next digit in the result. 
Result so far: 6717.316103
Subtracting 1509 from 1700 leaves us 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.

Going ahead to step 14:
When dividing 1910 by 503, we get 3 with a remainder of 401.
The next digit of our result is 3. 
Result so far: 6717.3161033
If we take 1509 away from 1910, we end up 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 6717.3161033, and the remainder is 4.01e-06.
