6720289 ÷ 449 
We want to divide 6720289 by 449.

Step 1:
449 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 449

On to step 2:
The number 449 fits into 67 0 times, leaving a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (2) from the dividend, add it to 67, then carry on: 672 / 449

Moving on to step 3:
The number 449 fits into 672 1 times, leaving a remainder of 223.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 449 from 672 and we're left with 223.
Append the next digit (0) from the dividend to 223 and continue with: 2230 / 449

Going ahead to step 4:
If we divide 2230 by 449, we get 4 and a remainder of 434.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 434 after subtracting 1796 from 2230.
Grab the next digit (2) from the dividend, add it to 434, then carry on: 4342 / 449

Moving on to step 5:
449 goes into 4342 9 times with a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 149.0
The remainder is 301 after subtracting 4041 from 4342.
Take the next digit (8) from the dividend and append it to 301, then repeat: 3018 / 449

Moving on to step 6:
The number 449 fits into 3018 6 times, leaving a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 1496.0
Deduct 2694 from 3018 and we're left with 324.
Include the next digit (9) from the dividend after 324, then repeat: 3249 / 449

Going ahead to step 7:
449 goes into 3249 7 times with a remainder of 106.
The next digit of our result is 7. 
Result so far: 14967.0
Deduct 3143 from 3249 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 8:
449 goes into 1060 2 times with a remainder of 162.
The next digit of our result is 2. 
Result so far: 14967.2
If we take 898 away from 1060, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 9:
When dividing 1620 by 449, we get 3 with a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 14967.23
The remainder is 273 after subtracting 1347 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 10:
2730 divided by 449 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 14967.236
If we take 2694 away from 2730, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 449 fits into 360 0 times, leaving a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 14967.236
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 12:
The number 449 fits into 3600 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 14967.23608
Subtracting 3592 from 3600 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
If we divide 80 by 449, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 14967.23608
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
If we divide 800 by 449, we get 1 and a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 14967.2360801
If we take 449 away from 800, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 15:
If we divide 3510 by 449, we get 7 and a remainder of 367.
Record the quotient 7 as the next digit in the result. 
Result so far: 14967.23608017
If we subtract 3143 from 3510, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

The final result is 14967.23608017 with a remainder of 3.67e-07.
