We divide 490143 by 45
Let's see how many times 45 fits into 490143.

On to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 45

Advancing to step 2:
The number 45 fits into 49 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 49 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 45

Moving on to step 3:
45 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 45

Moving on to step 4:
When dividing 401 by 45, we get 8 with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we take 360 away from 401, we end up with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 45

Moving on to step 5:
The number 45 fits into 414 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
If we subtract 405 from 414, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 45

Let's proceed to step 6:
The number 45 fits into 93 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 10892.0
If we subtract 90 from 93, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
45 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10892.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 45, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 10892.06
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 10892.066
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 10892.066, with a leftover of 0.003.
