Let's divide 821015 by 64
Let's see how many times 64 fits into 821015.

Advancing to step 1:
When dividing 8 by 64, we get 0 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.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 64

Step 2:
The number 64 fits into 82 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 64 away from 82, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 64

Moving on to step 3:
When dividing 181 by 64, we get 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 128 from 181, we get 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 64

Advancing to step 4:
530 divided by 64 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 128.0
Subtract 512 from 530 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 64

Advancing to step 5:
181 divided by 64 is 2 with a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 1282.0
If we subtract 128 from 181, we get 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 64

On to step 6:
64 goes into 535 8 times with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 12828.0
Subtract 512 from 535 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
When dividing 230 by 64, we get 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 12828.3
The remainder is 38 after subtracting 192 from 230.
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 8:
When dividing 380 by 64, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 12828.35
Deduct 320 from 380 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
600 divided by 64 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 12828.359
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 64, we get 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 12828.3593
Subtract 192 from 240 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.

Advancing to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 12828.35937
Deduct 448 from 480 and we're left 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.

Let's proceed to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12828.359375
If we take 320 away from 320, 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.

On to step 13:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12828.359375
If we subtract 0 from 0, we 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.

Going ahead to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12828.359375
Deduct 0 from 0 and we're left 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.

The final outcome is 12828.359375, with a leftover of 0.0.
