6470821 ÷ 305 
Let's see how many times 305 fits into 6470821.

Advancing to step 1:
6 divided by 305 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 305

Moving on to step 2:
When dividing 64 by 305, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 305

On to step 3:
The number 305 fits into 647 2 times, leaving a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 610 away from 647, we end up with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 305

Step 4:
If we divide 370 by 305, we get 1 and a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 305 from 370 and we're left with 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 305

On to step 5:
305 goes into 658 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 212.0
Deduct 610 from 658 and we're left with 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 305

Advancing to step 6:
305 goes into 482 1 times with a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 2121.0
Subtracting 305 from 482 leaves us with 177.
Take the next digit (1) from the dividend and append it to 177, then repeat: 1771 / 305

Moving on to step 7:
When dividing 1771 by 305, we get 5 with a remainder of 246.
The number 5 becomes the next digit in our result. 
Result so far: 21215.0
Subtract 1525 from 1771 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 8:
2460 divided by 305 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 21215.8
If we subtract 2440 from 2460, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 305, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 21215.8
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
2000 divided by 305 is 6 with a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 21215.806
If we take 1830 away from 2000, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
305 can be fit into 1700 5 times, resulting in a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 21215.8065
If we take 1525 away from 1700, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 12:
305 goes into 1750 5 times with a remainder of 225.
The next digit of our result is 5. 
Result so far: 21215.80655
If we take 1525 away from 1750, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

In conclusion, the division gives 21215.80655 with a balance of 0.000225.
