We look at the division of 84123268 by 903 
We want to divide 84123268 by 903.

Going ahead to step 1:
8 divided by 903 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 903

Moving on to step 2:
The number 903 fits into 84 0 times, leaving a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 903

Going ahead to step 3:
When dividing 841 by 903, we get 0 with a remainder of 841.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 841, we end up with 841.
Bring next digit (2) of the dividend behind the 841 and repeat the process: 8412 / 903

On to step 4:
903 can be fit into 8412 9 times, resulting in a remainder of 285.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 8127 from 8412 and we're left with 285.
Fetch the next digit (3) from the dividend, attach it to 285 and continue: 2853 / 903

Moving on to step 5:
903 goes into 2853 3 times with a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtract 2709 from 2853 to get 144.
Append the next digit (2) from the dividend to 144 and continue with: 1442 / 903

Moving on to step 6:
903 can be fit into 1442 1 times, resulting in a remainder of 539.
Record the quotient 1 as the next digit in the result. 
Result so far: 931.0
If we subtract 903 from 1442, we get 539.
Grab the next digit (6) from the dividend, add it to 539, then carry on: 5396 / 903

Step 7:
If we divide 5396 by 903, we get 5 and a remainder of 881.
Put 5 as the next digit of the answer. 
Result so far: 9315.0
If we take 4515 away from 5396, we end up with 881.
Bring next digit (8) of the dividend behind the 881 and repeat the process: 8818 / 903

Let's proceed to step 8:
The number 903 fits into 8818 9 times, leaving a remainder of 691.
Write down 9 as next digit of the result. 
Result so far: 93159.0
Subtracting 8127 from 8818 leaves us with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Let's proceed to step 9:
903 goes into 6910 7 times with a remainder of 589.
Record the quotient 7 as the next digit in the result. 
Result so far: 93159.7
Subtract 6321 from 6910 to get 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Moving on to step 10:
If we divide 5890 by 903, we get 6 and a remainder of 472.
The number 6 becomes the next digit in our result. 
Result so far: 93159.76
Deduct 5418 from 5890 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 11:
The number 903 fits into 4720 5 times, leaving a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 93159.765
Subtracting 4515 from 4720 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 12:
903 can be fit into 2050 2 times, resulting in a remainder of 244.
The number 2 becomes the next digit in our result. 
Result so far: 93159.7652
Deduct 1806 from 2050 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 13:
When dividing 2440 by 903, we get 2 with a remainder of 634.
The next digit of our result is 2. 
Result so far: 93159.76522
If we subtract 1806 from 2440, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

The final outcome is 93159.76522, with a leftover of 0.000634.
