We're dividing 21828337 by 145 
Let's see how many times 145 fits into 21828337.

Advancing to step 1:
2 divided by 145 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 145

On to step 2:
21 divided by 145 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 145

On to step 3:
If we divide 218 by 145, we get 1 and a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 145 away from 218, we end up with 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 145

Moving on to step 4:
The number 145 fits into 732 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 725 from 732 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 145

Step 5:
The number 145 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 145

On to step 6:
145 can be fit into 783 5 times, resulting in a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 1505.0
If we take 725 away from 783, we end up with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 145

Advancing to step 7:
The number 145 fits into 583 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 15054.0
Subtract 580 from 583 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 145

Step 8:
The number 145 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 150540.0
If we take 0 away from 37, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
370 divided by 145 is 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 150540.2
Deduct 290 from 370 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
145 can be fit into 800 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 150540.25
Subtracting 725 from 800 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
145 can be fit into 750 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 150540.255
Subtract 725 from 750 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 150540.255 with a remainder of 0.0025.
