We're dividing 6721530 by 649 
Let's see how many times 649 fits into 6721530.

On to step 1:
649 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 649

Step 2:
When dividing 67 by 649, we get 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 649

On to step 3:
649 can be fit into 672 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 649 from 672 and we're left with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 649

Advancing to step 4:
649 can be fit into 231 0 times, resulting in a remainder of 231.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 231, we end up with 231.
Bring next digit (5) of the dividend behind the 231 and repeat the process: 2315 / 649

Let's proceed to step 5:
When dividing 2315 by 649, we get 3 with a remainder of 368.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtract 1947 from 2315 to get 368.
Include the next digit (3) from the dividend after 368, then repeat: 3683 / 649

Step 6:
649 can be fit into 3683 5 times, resulting in a remainder of 438.
The number 5 becomes the next digit in our result. 
Result so far: 1035.0
Subtract 3245 from 3683 to get 438.
Bring next digit (0) of the dividend behind the 438 and repeat the process: 4380 / 649

Let's proceed to step 7:
649 can be fit into 4380 6 times, resulting in a remainder of 486.
The number 6 becomes the next digit in our result. 
Result so far: 10356.0
If we subtract 3894 from 4380, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 8:
4860 divided by 649 is 7 with a remainder of 317.
The number 7 becomes the next digit in our result. 
Result so far: 10356.7
Deduct 4543 from 4860 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 9:
3170 divided by 649 is 4 with a remainder of 574.
The number 4 becomes the next digit in our result. 
Result so far: 10356.74
If we subtract 2596 from 3170, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 10:
The number 649 fits into 5740 8 times, leaving a remainder of 548.
Use 8 as the next digit of our solution. 
Result so far: 10356.748
Subtract 5192 from 5740 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 11:
When dividing 5480 by 649, we get 8 with a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 10356.7488
Subtract 5192 from 5480 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 10356.7488, with a leftover of 0.00288.
