We divide 21210496 by 305
Let's see how many times 305 fits into 21210496.

Moving on to step 1:
2 divided by 305 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 305

On to step 2:
21 divided by 305 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 305

Moving on to step 3:
305 goes into 212 0 times with a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Bring next digit (1) of the dividend behind the 212 and repeat the process: 2121 / 305

Step 4:
2121 divided by 305 is 6 with a remainder of 291.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 1830 from 2121 leaves us with 291.
Fetch the next digit (0) from the dividend, attach it to 291 and continue: 2910 / 305

Step 5:
The number 305 fits into 2910 9 times, leaving a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 2745 from 2910 leaves us with 165.
Fetch the next digit (4) from the dividend, attach it to 165 and continue: 1654 / 305

Step 6:
When dividing 1654 by 305, we get 5 with a remainder of 129.
Write down 5 as next digit of the result. 
Result so far: 695.0
Subtract 1525 from 1654 to get 129.
Bring next digit (9) of the dividend behind the 129 and repeat the process: 1299 / 305

Step 7:
305 goes into 1299 4 times with a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 6954.0
Subtract 1220 from 1299 to get 79.
Grab the next digit (6) from the dividend, add it to 79, then carry on: 796 / 305

Moving on to step 8:
796 divided by 305 is 2 with a remainder of 186.
Use 2 as the next digit of our solution. 
Result so far: 69542.0
If we take 610 away from 796, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 9:
305 goes into 1860 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 69542.6
Deduct 1830 from 1860 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 305, we get 0 and a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 69542.6
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
3000 divided by 305 is 9 with a remainder of 255.
The number 9 becomes the next digit in our result. 
Result so far: 69542.609
The remainder is 255 after subtracting 2745 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 12:
2550 divided by 305 is 8 with a remainder of 110.
Put 8 as the next digit of the answer. 
Result so far: 69542.6098
If we subtract 2440 from 2550, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 13:
305 goes into 1100 3 times with a remainder of 185.
Record the quotient 3 as the next digit in the result. 
Result so far: 69542.60983
The remainder is 185 after subtracting 915 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 14:
The number 305 fits into 1850 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 69542.609836
If we take 1830 away from 1850, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
200 divided by 305 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 69542.609836
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
305 can be fit into 2000 6 times, resulting in a remainder of 170.
Write down 6 as next digit of the result. 
Result so far: 69542.60983606
If we subtract 1830 from 2000, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 69542.60983606 with a balance of 1.7e-07.
