We look at the division of 820456 by 64 
We're looking to find how many times 64 goes into 820456.

Step 1:
64 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 64

Going ahead to step 2:
82 divided by 64 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 18 after subtracting 64 from 82.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 64

Let's proceed to step 3:
If we divide 180 by 64, we get 2 and a remainder of 52.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 128 from 180 to get 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 64

Advancing to step 4:
The number 64 fits into 524 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Deduct 512 from 524 and we're left with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 64

Moving on to step 5:
64 goes into 125 1 times with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1281.0
Deduct 64 from 125 and we're left with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 64

Let's proceed to step 6:
The number 64 fits into 616 9 times, leaving a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 12819.0
Deduct 576 from 616 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
When dividing 400 by 64, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 12819.6
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 12819.62
Subtracting 128 from 160 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
If we divide 320 by 64, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12819.625
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12819.625
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.

Going ahead to step 11:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12819.625
Subtract 0 from 0 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.

After the division, we end up with 12819.625 and a remainder of 0.0.
