Let's divide 20001290 by 449
We want to figure out the number of times 20001290 can be divided by 449.

Going ahead to step 1:
2 divided by 449 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 449

Let's proceed to step 2:
If we divide 20 by 449, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 449

Advancing to step 3:
When dividing 200 by 449, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 200 to get 200.
Grab the next digit (0) from the dividend, add it to 200, then carry on: 2000 / 449

Advancing to step 4:
When dividing 2000 by 449, we get 4 with a remainder of 204.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 204 after subtracting 1796 from 2000.
Append the next digit (1) from the dividend to 204 and continue with: 2041 / 449

Step 5:
The number 449 fits into 2041 4 times, leaving a remainder of 245.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 1796 from 2041, we get 245.
Fetch the next digit (2) from the dividend, attach it to 245 and continue: 2452 / 449

On to step 6:
449 goes into 2452 5 times with a remainder of 207.
Use 5 as the next digit of our solution. 
Result so far: 445.0
If we subtract 2245 from 2452, we get 207.
Grab the next digit (9) from the dividend, add it to 207, then carry on: 2079 / 449

Advancing to step 7:
When dividing 2079 by 449, we get 4 with a remainder of 283.
The number 4 becomes the next digit in our result. 
Result so far: 4454.0
The remainder is 283 after subtracting 1796 from 2079.
Include the next digit (0) from the dividend after 283, then repeat: 2830 / 449

Moving on to step 8:
When dividing 2830 by 449, we get 6 with a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 44546.0
The remainder is 136 after subtracting 2694 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 9:
1360 divided by 449 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 44546.3
Deduct 1347 from 1360 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
When dividing 130 by 449, we get 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 44546.3
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
449 can be fit into 1300 2 times, resulting in a remainder of 402.
Write down 2 as next digit of the result. 
Result so far: 44546.302
Deduct 898 from 1300 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 12:
4020 divided by 449 is 8 with a remainder of 428.
The next digit of our result is 8. 
Result so far: 44546.3028
Subtract 3592 from 4020 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 13:
The number 449 fits into 4280 9 times, leaving a remainder of 239.
Write down 9 as next digit of the result. 
Result so far: 44546.30289
Subtracting 4041 from 4280 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 14:
If we divide 2390 by 449, we get 5 and a remainder of 145.
The next digit of our result is 5. 
Result so far: 44546.302895
If we subtract 2245 from 2390, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 15:
When dividing 1450 by 449, we get 3 with a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 44546.3028953
If we take 1347 away from 1450, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 16:
449 can be fit into 1030 2 times, resulting in a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 44546.30289532
The remainder is 132 after subtracting 898 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 44546.30289532 with a remainder of 1.32e-07.
