We look at the division of 8156354 by 504 
Let's see how many times 504 fits into 8156354.

Step 1:
If we divide 8 by 504, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 504

Step 2:
504 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 504

Advancing to step 3:
504 goes into 815 1 times with a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 311 after subtracting 504 from 815.
Take the next digit (6) from the dividend and append it to 311, then repeat: 3116 / 504

Step 4:
504 can be fit into 3116 6 times, resulting in a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 3024 from 3116 to get 92.
Take the next digit (3) from the dividend and append it to 92, then repeat: 923 / 504

Step 5:
923 divided by 504 is 1 with a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Subtracting 504 from 923 leaves us with 419.
Grab the next digit (5) from the dividend, add it to 419, then carry on: 4195 / 504

Let's proceed to step 6:
504 goes into 4195 8 times with a remainder of 163.
Record the quotient 8 as the next digit in the result. 
Result so far: 1618.0
If we take 4032 away from 4195, we end up with 163.
Fetch the next digit (4) from the dividend, attach it to 163 and continue: 1634 / 504

On to step 7:
504 goes into 1634 3 times with a remainder of 122.
The next digit of our result is 3. 
Result so far: 16183.0
If we take 1512 away from 1634, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 8:
504 goes into 1220 2 times with a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 16183.2
If we take 1008 away from 1220, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 9:
2120 divided by 504 is 4 with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 16183.24
If we subtract 2016 from 2120, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
If we divide 1040 by 504, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 16183.242
If we subtract 1008 from 1040, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
If we divide 320 by 504, we get 0 and a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 16183.242
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
504 goes into 3200 6 times with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 16183.24206
Subtract 3024 from 3200 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 13:
When dividing 1760 by 504, we get 3 with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 16183.242063
The remainder is 248 after subtracting 1512 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 14:
The number 504 fits into 2480 4 times, leaving a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 16183.2420634
Subtract 2016 from 2480 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 15:
If we divide 4640 by 504, we get 9 and a remainder of 104.
The next digit of our result is 9. 
Result so far: 16183.24206349
Deduct 4536 from 4640 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 16183.24206349 and a remainder of 1.04e-07.
