Let's divide 21852711 by 456
Let's see how many times 456 fits into 21852711.

Advancing to step 1:
2 divided by 456 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 456

Advancing to step 2:
If we divide 21 by 456, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 456

On to step 3:
456 can be fit into 218 0 times, resulting in a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 218 after subtracting 0 from 218.
Take the next digit (5) from the dividend and append it to 218, then repeat: 2185 / 456

Going ahead to step 4:
456 can be fit into 2185 4 times, resulting in a remainder of 361.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1824 from 2185, we get 361.
Include the next digit (2) from the dividend after 361, then repeat: 3612 / 456

Advancing to step 5:
If we divide 3612 by 456, we get 7 and a remainder of 420.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
The remainder is 420 after subtracting 3192 from 3612.
Include the next digit (7) from the dividend after 420, then repeat: 4207 / 456

Advancing to step 6:
4207 divided by 456 is 9 with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 479.0
If we take 4104 away from 4207, we end up with 103.
Bring next digit (1) of the dividend behind the 103 and repeat the process: 1031 / 456

On to step 7:
The number 456 fits into 1031 2 times, leaving a remainder of 119.
Use 2 as the next digit of our solution. 
Result so far: 4792.0
Deduct 912 from 1031 and we're left with 119.
Bring next digit (1) of the dividend behind the 119 and repeat the process: 1191 / 456

Let's proceed to step 8:
456 goes into 1191 2 times with a remainder of 279.
Use 2 as the next digit of our solution. 
Result so far: 47922.0
If we take 912 away from 1191, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 9:
456 goes into 2790 6 times with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 47922.6
If we subtract 2736 from 2790, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
456 goes into 540 1 times with a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 47922.61
Subtracting 456 from 540 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
If we divide 840 by 456, we get 1 and a remainder of 384.
Put 1 as the next digit of the answer. 
Result so far: 47922.611
The remainder is 384 after subtracting 456 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 47922.611, with a leftover of 0.0384.
