We're dividing 21929510 by 256 
We're looking to find how many times 256 goes into 21929510.

Going ahead to step 1:
If we divide 2 by 256, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 256

Going ahead to step 2:
The number 256 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 256

Let's proceed to step 3:
The number 256 fits into 219 0 times, leaving a remainder of 219.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Fetch the next digit (2) from the dividend, attach it to 219 and continue: 2192 / 256

Step 4:
256 can be fit into 2192 8 times, resulting in a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 2048 from 2192, we get 144.
Include the next digit (9) from the dividend after 144, then repeat: 1449 / 256

Let's proceed to step 5:
When dividing 1449 by 256, we get 5 with a remainder of 169.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 169 after subtracting 1280 from 1449.
Include the next digit (5) from the dividend after 169, then repeat: 1695 / 256

Advancing to step 6:
If we divide 1695 by 256, we get 6 and a remainder of 159.
Write down 6 as next digit of the result. 
Result so far: 856.0
If we take 1536 away from 1695, we end up with 159.
Take the next digit (1) from the dividend and append it to 159, then repeat: 1591 / 256

On to step 7:
The number 256 fits into 1591 6 times, leaving a remainder of 55.
The next digit of our result is 6. 
Result so far: 8566.0
If we subtract 1536 from 1591, we get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 256

On to step 8:
When dividing 550 by 256, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 85662.0
Subtracting 512 from 550 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
If we divide 380 by 256, we get 1 and a remainder of 124.
The next digit of our result is 1. 
Result so far: 85662.1
Subtracting 256 from 380 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 10:
When dividing 1240 by 256, we get 4 with a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 85662.14
Deduct 1024 from 1240 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 11:
When dividing 2160 by 256, we get 8 with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 85662.148
The remainder is 112 after subtracting 2048 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
256 goes into 1120 4 times with a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 85662.1484
The remainder is 96 after subtracting 1024 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 13:
If we divide 960 by 256, we get 3 and a remainder of 192.
The number 3 becomes the next digit in our result. 
Result so far: 85662.14843
If we subtract 768 from 960, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 14:
1920 divided by 256 is 7 with a remainder of 128.
Put 7 as the next digit of the answer. 
Result so far: 85662.148437
Subtract 1792 from 1920 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
When dividing 1280 by 256, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 85662.1484375
Subtract 1280 from 1280 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
When dividing 0 by 256, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 85662.1484375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 85662.1484375 with a remaining 0.0.
