We're dividing 20001245 by 493 
We want to divide 20001245 by 493.

On to step 1:
493 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 493

Step 2:
493 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 493

Going ahead to step 3:
493 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 200 and we're left with 200.
Fetch the next digit (0) from the dividend, attach it to 200 and continue: 2000 / 493

Advancing to step 4:
When dividing 2000 by 493, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 1972 from 2000 leaves us with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 493

Moving on to step 5:
If we divide 281 by 493, we get 0 and a remainder of 281.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 281 after subtracting 0 from 281.
Fetch the next digit (2) from the dividend, attach it to 281 and continue: 2812 / 493

Let's proceed to step 6:
493 goes into 2812 5 times with a remainder of 347.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
Deduct 2465 from 2812 and we're left with 347.
Take the next digit (4) from the dividend and append it to 347, then repeat: 3474 / 493

Going ahead to step 7:
493 goes into 3474 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 4057.0
Subtract 3451 from 3474 to get 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 493

On to step 8:
The number 493 fits into 235 0 times, leaving a remainder of 235.
The number 0 becomes the next digit in our result. 
Result so far: 40570.0
Subtract 0 from 235 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 9:
493 can be fit into 2350 4 times, resulting in a remainder of 378.
The next digit of our result is 4. 
Result so far: 40570.4
The remainder is 378 after subtracting 1972 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 10:
3780 divided by 493 is 7 with a remainder of 329.
Use 7 as the next digit of our solution. 
Result so far: 40570.47
Subtracting 3451 from 3780 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 11:
If we divide 3290 by 493, we get 6 and a remainder of 332.
The number 6 becomes the next digit in our result. 
Result so far: 40570.476
If we take 2958 away from 3290, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 12:
3320 divided by 493 is 6 with a remainder of 362.
Record the quotient 6 as the next digit in the result. 
Result so far: 40570.4766
The remainder is 362 after subtracting 2958 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

After the division, we end up with 40570.4766 and a remainder of 0.00362.
