We look at the division of 21045997 by 495 
We're looking to find how many times 495 goes into 21045997.

Going ahead to step 1:
If we divide 2 by 495, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 495

Going ahead to step 2:
If we divide 21 by 495, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 495

Let's proceed to step 3:
495 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Append the next digit (4) from the dividend to 210 and continue with: 2104 / 495

Step 4:
When dividing 2104 by 495, we get 4 with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1980 from 2104 and we're left with 124.
Take the next digit (5) from the dividend and append it to 124, then repeat: 1245 / 495

Step 5:
If we divide 1245 by 495, we get 2 and a remainder of 255.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 990 from 1245 and we're left with 255.
Include the next digit (9) from the dividend after 255, then repeat: 2559 / 495

Going ahead to step 6:
If we divide 2559 by 495, we get 5 and a remainder of 84.
Use 5 as the next digit of our solution. 
Result so far: 425.0
Subtracting 2475 from 2559 leaves us with 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 495

Let's proceed to step 7:
495 goes into 849 1 times with a remainder of 354.
Write down 1 as next digit of the result. 
Result so far: 4251.0
The remainder is 354 after subtracting 495 from 849.
Take the next digit (7) from the dividend and append it to 354, then repeat: 3547 / 495

Going ahead to step 8:
495 can be fit into 3547 7 times, resulting in a remainder of 82.
The next digit of our result is 7. 
Result so far: 42517.0
If we subtract 3465 from 3547, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
If we divide 820 by 495, we get 1 and a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 42517.1
If we subtract 495 from 820, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 10:
If we divide 3250 by 495, we get 6 and a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 42517.16
If we subtract 2970 from 3250, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
495 can be fit into 2800 5 times, resulting in a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 42517.165
Deduct 2475 from 2800 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 12:
The number 495 fits into 3250 6 times, leaving a remainder of 280.
The next digit of our result is 6. 
Result so far: 42517.1656
Subtract 2970 from 3250 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
If we divide 2800 by 495, we get 5 and a remainder of 325.
The next digit of our result is 5. 
Result so far: 42517.16565
Subtracting 2475 from 2800 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 14:
When dividing 3250 by 495, we get 6 with a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 42517.165656
The remainder is 280 after subtracting 2970 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 15:
When dividing 2800 by 495, we get 5 with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 42517.1656565
The remainder is 325 after subtracting 2475 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 16:
3250 divided by 495 is 6 with a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 42517.16565656
If we take 2970 away from 3250, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 42517.16565656, with a leftover of 2.8e-07.
