21839280 ÷ 472 
We want to figure out the number of times 21839280 can be divided by 472.

Let's proceed to step 1:
2 divided by 472 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 472

Going ahead to step 2:
The number 472 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 472

Let's proceed to step 3:
If we divide 218 by 472, we get 0 and a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Append the next digit (3) from the dividend to 218 and continue with: 2183 / 472

Let's proceed to step 4:
472 can be fit into 2183 4 times, resulting in a remainder of 295.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1888 from 2183, we get 295.
Bring next digit (9) of the dividend behind the 295 and repeat the process: 2959 / 472

Moving on to step 5:
If we divide 2959 by 472, we get 6 and a remainder of 127.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 2832 away from 2959, we end up with 127.
Fetch the next digit (2) from the dividend, attach it to 127 and continue: 1272 / 472

Going ahead to step 6:
472 can be fit into 1272 2 times, resulting in a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 462.0
Deduct 944 from 1272 and we're left with 328.
Bring next digit (8) of the dividend behind the 328 and repeat the process: 3288 / 472

Step 7:
3288 divided by 472 is 6 with a remainder of 456.
The next digit of our result is 6. 
Result so far: 4626.0
If we take 2832 away from 3288, we end up with 456.
Take the next digit (0) from the dividend and append it to 456, then repeat: 4560 / 472

Step 8:
4560 divided by 472 is 9 with a remainder of 312.
Write down 9 as next digit of the result. 
Result so far: 46269.0
Subtract 4248 from 4560 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 9:
3120 divided by 472 is 6 with a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 46269.6
Deduct 2832 from 3120 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 10:
2880 divided by 472 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 46269.66
Subtract 2832 from 2880 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 46269.66 and a remainder of 0.048.
