Let's see how many times 903 fits into 42128976.

Let's proceed to step 1:
The number 903 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 903

Moving on to step 2:
If we divide 42 by 903, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 903

Advancing to step 3:
903 can be fit into 421 0 times, resulting in a remainder of 421.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 421, we end up with 421.
Grab the next digit (2) from the dividend, add it to 421, then carry on: 4212 / 903

Advancing to step 4:
4212 divided by 903 is 4 with a remainder of 600.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3612 from 4212 leaves us with 600.
Fetch the next digit (8) from the dividend, attach it to 600 and continue: 6008 / 903

Advancing to step 5:
903 goes into 6008 6 times with a remainder of 590.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 590 after subtracting 5418 from 6008.
Include the next digit (9) from the dividend after 590, then repeat: 5909 / 903

Going ahead to step 6:
903 can be fit into 5909 6 times, resulting in a remainder of 491.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
Deduct 5418 from 5909 and we're left with 491.
Take the next digit (7) from the dividend and append it to 491, then repeat: 4917 / 903

On to step 7:
When dividing 4917 by 903, we get 5 with a remainder of 402.
Record the quotient 5 as the next digit in the result. 
Result so far: 4665.0
Subtracting 4515 from 4917 leaves us with 402.
Take the next digit (6) from the dividend and append it to 402, then repeat: 4026 / 903

Moving on to step 8:
The number 903 fits into 4026 4 times, leaving a remainder of 414.
The next digit of our result is 4. 
Result so far: 46654.0
If we subtract 3612 from 4026, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 9:
903 goes into 4140 4 times with a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 46654.4
The remainder is 528 after subtracting 3612 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 10:
903 can be fit into 5280 5 times, resulting in a remainder of 765.
The number 5 becomes the next digit in our result. 
Result so far: 46654.45
Subtract 4515 from 5280 to get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Let's proceed to step 11:
The number 903 fits into 7650 8 times, leaving a remainder of 426.
The number 8 becomes the next digit in our result. 
Result so far: 46654.458
If we subtract 7224 from 7650, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 12:
4260 divided by 903 is 4 with a remainder of 648.
The number 4 becomes the next digit in our result. 
Result so far: 46654.4584
If we subtract 3612 from 4260, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 13:
903 goes into 6480 7 times with a remainder of 159.
The number 7 becomes the next digit in our result. 
Result so far: 46654.45847
Subtract 6321 from 6480 to 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.

Let's proceed to step 14:
The number 903 fits into 1590 1 times, leaving a remainder of 687.
Put 1 as the next digit of the answer. 
Result so far: 46654.458471
Deduct 903 from 1590 and we're left 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.

Advancing to step 15:
6870 divided by 903 is 7 with a remainder of 549.
The next digit of our result is 7. 
Result so far: 46654.4584717
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.

Let's proceed to step 16:
903 can be fit into 5490 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 46654.45847176
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.

Our division results in 46654.45847176 with a remaining 7.2e-08.
