Let's divide 78312335 by 903
We're looking to find how many times 903 goes into 78312335.

Advancing to step 1:
903 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 903

Moving on to step 2:
If we divide 78 by 903, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 903

Moving on to step 3:
If we divide 783 by 903, we get 0 and a remainder of 783.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 783 after subtracting 0 from 783.
Append the next digit (1) from the dividend to 783 and continue with: 7831 / 903

Let's proceed to step 4:
If we divide 7831 by 903, we get 8 and a remainder of 607.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7224 from 7831 to get 607.
Grab the next digit (2) from the dividend, add it to 607, then carry on: 6072 / 903

Step 5:
If we divide 6072 by 903, we get 6 and a remainder of 654.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 5418 from 6072 to get 654.
Include the next digit (3) from the dividend after 654, then repeat: 6543 / 903

Step 6:
903 goes into 6543 7 times with a remainder of 222.
Write down 7 as next digit of the result. 
Result so far: 867.0
Subtract 6321 from 6543 to get 222.
Take the next digit (3) from the dividend and append it to 222, then repeat: 2223 / 903

Moving on to step 7:
903 can be fit into 2223 2 times, resulting in a remainder of 417.
The next digit of our result is 2. 
Result so far: 8672.0
The remainder is 417 after subtracting 1806 from 2223.
Take the next digit (5) from the dividend and append it to 417, then repeat: 4175 / 903

Let's proceed to step 8:
903 can be fit into 4175 4 times, resulting in a remainder of 563.
Use 4 as the next digit of our solution. 
Result so far: 86724.0
Subtracting 3612 from 4175 leaves us with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 9:
903 goes into 5630 6 times with a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 86724.6
Subtract 5418 from 5630 to get 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 10:
If we divide 2120 by 903, we get 2 and a remainder of 314.
The next digit of our result is 2. 
Result so far: 86724.62
Subtract 1806 from 2120 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 11:
3140 divided by 903 is 3 with a remainder of 431.
The next digit of our result is 3. 
Result so far: 86724.623
If we take 2709 away from 3140, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 12:
903 can be fit into 4310 4 times, resulting in a remainder of 698.
Put 4 as the next digit of the answer. 
Result so far: 86724.6234
The remainder is 698 after subtracting 3612 from 4310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Let's proceed to step 13:
903 can be fit into 6980 7 times, resulting in a remainder of 659.
Write down 7 as next digit of the result. 
Result so far: 86724.62347
Subtracting 6321 from 6980 leaves us with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Step 14:
If we divide 6590 by 903, we get 7 and a remainder of 269.
Record the quotient 7 as the next digit in the result. 
Result so far: 86724.623477
If we take 6321 away from 6590, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 86724.623477, with a leftover of 2.69e-05.
