Let's divide 8915178 by 903
We want to divide 8915178 by 903.

On to step 1:
When dividing 8 by 903, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 903

Step 2:
903 can be fit into 89 0 times, resulting in a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 903

Moving on to step 3:
903 can be fit into 891 0 times, resulting in a remainder of 891.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 891 and we're left with 891.
Append the next digit (5) from the dividend to 891 and continue with: 8915 / 903

Moving on to step 4:
8915 divided by 903 is 9 with a remainder of 788.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 8127 from 8915 leaves us with 788.
Bring next digit (1) of the dividend behind the 788 and repeat the process: 7881 / 903

Advancing to step 5:
903 can be fit into 7881 8 times, resulting in a remainder of 657.
The next digit of our result is 8. 
Result so far: 98.0
If we take 7224 away from 7881, we end up with 657.
Take the next digit (7) from the dividend and append it to 657, then repeat: 6577 / 903

Advancing to step 6:
6577 divided by 903 is 7 with a remainder of 256.
Write down 7 as next digit of the result. 
Result so far: 987.0
Subtracting 6321 from 6577 leaves us with 256.
Include the next digit (8) from the dividend after 256, then repeat: 2568 / 903

Moving on to step 7:
903 goes into 2568 2 times with a remainder of 762.
Put 2 as the next digit of the answer. 
Result so far: 9872.0
Deduct 1806 from 2568 and we're left with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Advancing to step 8:
When dividing 7620 by 903, we get 8 with a remainder of 396.
The number 8 becomes the next digit in our result. 
Result so far: 9872.8
If we take 7224 away from 7620, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 9:
The number 903 fits into 3960 4 times, leaving a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 9872.84
Subtracting 3612 from 3960 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 10:
If we divide 3480 by 903, we get 3 and a remainder of 771.
Put 3 as the next digit of the answer. 
Result so far: 9872.843
Subtract 2709 from 3480 to get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Going ahead to step 11:
If we divide 7710 by 903, we get 8 and a remainder of 486.
The number 8 becomes the next digit in our result. 
Result so far: 9872.8438
Subtracting 7224 from 7710 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 12:
The number 903 fits into 4860 5 times, leaving a remainder of 345.
Write down 5 as next digit of the result. 
Result so far: 9872.84385
If we take 4515 away from 4860, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 13:
3450 divided by 903 is 3 with a remainder of 741.
Use 3 as the next digit of our solution. 
Result so far: 9872.843853
If we take 2709 away from 3450, we end up with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Let's proceed to step 14:
If we divide 7410 by 903, we get 8 and a remainder of 186.
The next digit of our result is 8. 
Result so far: 9872.8438538
If we take 7224 away from 7410, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 15:
1860 divided by 903 is 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 9872.84385382
Subtracting 1806 from 1860 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 9872.84385382, with a leftover of 5.4e-08.
