6407185 ÷ 504 
We want to divide 6407185 by 504.

Going ahead to step 1:
When dividing 6 by 504, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 504

Advancing to step 2:
504 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 504

Moving on to step 3:
504 can be fit into 640 1 times, resulting in a remainder of 136.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 136 after subtracting 504 from 640.
Bring next digit (7) of the dividend behind the 136 and repeat the process: 1367 / 504

Let's proceed to step 4:
504 can be fit into 1367 2 times, resulting in a remainder of 359.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 359 after subtracting 1008 from 1367.
Take the next digit (1) from the dividend and append it to 359, then repeat: 3591 / 504

Moving on to step 5:
504 can be fit into 3591 7 times, resulting in a remainder of 63.
The next digit of our result is 7. 
Result so far: 127.0
Subtracting 3528 from 3591 leaves us with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 504

Advancing to step 6:
504 goes into 638 1 times with a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1271.0
The remainder is 134 after subtracting 504 from 638.
Include the next digit (5) from the dividend after 134, then repeat: 1345 / 504

Step 7:
The number 504 fits into 1345 2 times, leaving a remainder of 337.
The number 2 becomes the next digit in our result. 
Result so far: 12712.0
Deduct 1008 from 1345 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 8:
504 goes into 3370 6 times with a remainder of 346.
Use 6 as the next digit of our solution. 
Result so far: 12712.6
If we subtract 3024 from 3370, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 9:
If we divide 3460 by 504, we get 6 and a remainder of 436.
Record the quotient 6 as the next digit in the result. 
Result so far: 12712.66
If we take 3024 away from 3460, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The final result is 12712.66 with a remainder of 0.436.
