Let's divide 21422018 by 903
We want to divide 21422018 by 903.

Moving on to step 1:
If we divide 2 by 903, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 903

Let's proceed to step 2:
903 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 903

On to step 3:
If we divide 214 by 903, we get 0 and a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 903

Moving on to step 4:
The number 903 fits into 2142 2 times, leaving a remainder of 336.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1806 from 2142 and we're left with 336.
Append the next digit (2) from the dividend to 336 and continue with: 3362 / 903

Step 5:
903 goes into 3362 3 times with a remainder of 653.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 2709 from 3362, we get 653.
Append the next digit (0) from the dividend to 653 and continue with: 6530 / 903

Step 6:
The number 903 fits into 6530 7 times, leaving a remainder of 209.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
If we take 6321 away from 6530, we end up with 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 903

Step 7:
If we divide 2091 by 903, we get 2 and a remainder of 285.
The next digit of our result is 2. 
Result so far: 2372.0
If we subtract 1806 from 2091, we get 285.
Include the next digit (8) from the dividend after 285, then repeat: 2858 / 903

Going ahead to step 8:
When dividing 2858 by 903, we get 3 with a remainder of 149.
The number 3 becomes the next digit in our result. 
Result so far: 23723.0
Subtract 2709 from 2858 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 9:
If we divide 1490 by 903, we get 1 and a remainder of 587.
The number 1 becomes the next digit in our result. 
Result so far: 23723.1
If we subtract 903 from 1490, we get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 10:
When dividing 5870 by 903, we get 6 with a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 23723.16
If we subtract 5418 from 5870, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 11:
4520 divided by 903 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 23723.165
If we subtract 4515 from 4520, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
903 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 23723.165
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
903 goes into 500 0 times with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 23723.165
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 23723.165 with a remaining 0.0005.
