We look at the division of 7782051 by 903 
Let's see how many times 903 fits into 7782051.

Let's proceed to step 1:
903 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 903

Going ahead to step 2:
If we divide 77 by 903, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 903

On to step 3:
778 divided by 903 is 0 with a remainder of 778.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 778 leaves us with 778.
Fetch the next digit (2) from the dividend, attach it to 778 and continue: 7782 / 903

Advancing to step 4:
7782 divided by 903 is 8 with a remainder of 558.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 7224 from 7782, we get 558.
Fetch the next digit (0) from the dividend, attach it to 558 and continue: 5580 / 903

On to step 5:
If we divide 5580 by 903, we get 6 and a remainder of 162.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 5418 from 5580 and we're left with 162.
Take the next digit (5) from the dividend and append it to 162, then repeat: 1625 / 903

Let's proceed to step 6:
If we divide 1625 by 903, we get 1 and a remainder of 722.
Record the quotient 1 as the next digit in the result. 
Result so far: 861.0
Deduct 903 from 1625 and we're left with 722.
Append the next digit (1) from the dividend to 722 and continue with: 7221 / 903

Step 7:
If we divide 7221 by 903, we get 7 and a remainder of 900.
The number 7 becomes the next digit in our result. 
Result so far: 8617.0
The remainder is 900 after subtracting 6321 from 7221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Advancing to step 8:
If we divide 9000 by 903, we get 9 and a remainder of 873.
Record the quotient 9 as the next digit in the result. 
Result so far: 8617.9
Subtracting 8127 from 9000 leaves us with 873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

On to step 9:
If we divide 8730 by 903, we get 9 and a remainder of 603.
The number 9 becomes the next digit in our result. 
Result so far: 8617.99
If we take 8127 away from 8730, we end up with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

The final outcome is 8617.99, with a leftover of 0.603.
