We look at the division of 5072310 by 903 
Let's see how many times 903 fits into 5072310.

On to step 1:
903 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 903

Step 2:
If we divide 50 by 903, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 903

Going ahead to step 3:
When dividing 507 by 903, we get 0 with a remainder of 507.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 507, we end up with 507.
Append the next digit (2) from the dividend to 507 and continue with: 5072 / 903

On to step 4:
903 goes into 5072 5 times with a remainder of 557.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 4515 from 5072 leaves us with 557.
Grab the next digit (3) from the dividend, add it to 557, then carry on: 5573 / 903

Moving on to step 5:
903 can be fit into 5573 6 times, resulting in a remainder of 155.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Deduct 5418 from 5573 and we're left with 155.
Include the next digit (1) from the dividend after 155, then repeat: 1551 / 903

Moving on to step 6:
1551 divided by 903 is 1 with a remainder of 648.
Use 1 as the next digit of our solution. 
Result so far: 561.0
If we take 903 away from 1551, we end up with 648.
Append the next digit (0) from the dividend to 648 and continue with: 6480 / 903

Let's proceed to step 7:
The number 903 fits into 6480 7 times, leaving a remainder of 159.
The next digit of our result is 7. 
Result so far: 5617.0
If we subtract 6321 from 6480, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 8:
The number 903 fits into 1590 1 times, leaving a remainder of 687.
The number 1 becomes the next digit in our result. 
Result so far: 5617.1
If we take 903 away from 1590, we end up with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Going ahead to step 9:
903 can be fit into 6870 7 times, resulting in a remainder of 549.
Write down 7 as next digit of the result. 
Result so far: 5617.17
The remainder is 549 after subtracting 6321 from 6870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 10:
5490 divided by 903 is 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 5617.176
Deduct 5418 from 5490 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
903 can be fit into 720 0 times, resulting in a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 5617.176
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 12:
7200 divided by 903 is 7 with a remainder of 879.
The number 7 becomes the next digit in our result. 
Result so far: 5617.17607
Deduct 6321 from 7200 and we're left with 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

On to step 13:
The number 903 fits into 8790 9 times, leaving a remainder of 663.
Put 9 as the next digit of the answer. 
Result so far: 5617.176079
Subtracting 8127 from 8790 leaves us with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Going ahead to step 14:
When dividing 6630 by 903, we get 7 with a remainder of 309.
Use 7 as the next digit of our solution. 
Result so far: 5617.1760797
If we subtract 6321 from 6630, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 15:
The number 903 fits into 3090 3 times, leaving a remainder of 381.
The next digit of our result is 3. 
Result so far: 5617.17607973
Subtract 2709 from 3090 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Our division results in 5617.17607973 with a remaining 3.81e-07.
