We look at the division of 3490811 by 503 
We want to divide 3490811 by 503.

Moving on to step 1:
When dividing 3 by 503, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 503

Step 2:
503 can be fit into 34 0 times, resulting in a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 503

Let's proceed to step 3:
349 divided by 503 is 0 with a remainder of 349.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 349, we get 349.
Include the next digit (0) from the dividend after 349, then repeat: 3490 / 503

Advancing to step 4:
If we divide 3490 by 503, we get 6 and a remainder of 472.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 3018 from 3490 to get 472.
Take the next digit (8) from the dividend and append it to 472, then repeat: 4728 / 503

Let's proceed to step 5:
503 goes into 4728 9 times with a remainder of 201.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 4527 from 4728 to get 201.
Fetch the next digit (1) from the dividend, attach it to 201 and continue: 2011 / 503

Moving on to step 6:
503 can be fit into 2011 3 times, resulting in a remainder of 502.
Put 3 as the next digit of the answer. 
Result so far: 693.0
Deduct 1509 from 2011 and we're left with 502.
Grab the next digit (1) from the dividend, add it to 502, then carry on: 5021 / 503

Let's proceed to step 7:
503 goes into 5021 9 times with a remainder of 494.
Record the quotient 9 as the next digit in the result. 
Result so far: 6939.0
Subtract 4527 from 5021 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 8:
When dividing 4940 by 503, we get 9 with a remainder of 413.
Write down 9 as next digit of the result. 
Result so far: 6939.9
Subtracting 4527 from 4940 leaves us with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 9:
4130 divided by 503 is 8 with a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 6939.98
The remainder is 106 after subtracting 4024 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 10:
503 can be fit into 1060 2 times, resulting in a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 6939.982
If we subtract 1006 from 1060, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
540 divided by 503 is 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 6939.9821
Deduct 503 from 540 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
503 can be fit into 370 0 times, resulting in a remainder of 370.
The number 0 becomes the next digit in our result. 
Result so far: 6939.9821
The remainder is 370 after subtracting 0 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 13:
503 can be fit into 3700 7 times, resulting in a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 6939.982107
If we take 3521 away from 3700, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 14:
1790 divided by 503 is 3 with a remainder of 281.
Record the quotient 3 as the next digit in the result. 
Result so far: 6939.9821073
Subtract 1509 from 1790 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 15:
The number 503 fits into 2810 5 times, leaving a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 6939.98210735
Subtract 2515 from 2810 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

After the division, we end up with 6939.98210735 and a remainder of 2.95e-07.
