21354025 ÷ 649 
Our goal is to divide 21354025 by 649.

Moving on to step 1:
If we divide 2 by 649, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 649

Going ahead to step 2:
If we divide 21 by 649, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 649

On to step 3:
When dividing 213 by 649, we get 0 with a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 213 after subtracting 0 from 213.
Fetch the next digit (5) from the dividend, attach it to 213 and continue: 2135 / 649

Let's proceed to step 4:
If we divide 2135 by 649, we get 3 and a remainder of 188.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1947 from 2135 and we're left with 188.
Bring next digit (4) of the dividend behind the 188 and repeat the process: 1884 / 649

Moving on to step 5:
649 goes into 1884 2 times with a remainder of 586.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 1298 from 1884 and we're left with 586.
Include the next digit (0) from the dividend after 586, then repeat: 5860 / 649

On to step 6:
If we divide 5860 by 649, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 329.0
Subtract 5841 from 5860 to get 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 649

Let's proceed to step 7:
192 divided by 649 is 0 with a remainder of 192.
The number 0 becomes the next digit in our result. 
Result so far: 3290.0
The remainder is 192 after subtracting 0 from 192.
Include the next digit (5) from the dividend after 192, then repeat: 1925 / 649

Moving on to step 8:
When dividing 1925 by 649, we get 2 with a remainder of 627.
Use 2 as the next digit of our solution. 
Result so far: 32902.0
Deduct 1298 from 1925 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Step 9:
649 can be fit into 6270 9 times, resulting in a remainder of 429.
Write down 9 as next digit of the result. 
Result so far: 32902.9
The remainder is 429 after subtracting 5841 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 10:
4290 divided by 649 is 6 with a remainder of 396.
Put 6 as the next digit of the answer. 
Result so far: 32902.96
If we take 3894 away from 4290, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 11:
When dividing 3960 by 649, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 32902.966
Subtract 3894 from 3960 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 32902.966 with a balance of 0.0066.
