We divide 852215 by 64
We want to figure out the number of times 852215 can be divided by 64.

Advancing to step 1:
8 divided by 64 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 64

Moving on to step 2:
When dividing 85 by 64, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 64 from 85 leaves us with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 64

Going ahead to step 3:
If we divide 212 by 64, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 192 from 212 to get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 64

Going ahead to step 4:
202 divided by 64 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Deduct 192 from 202 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 64

Going ahead to step 5:
When dividing 101 by 64, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1331.0
Subtracting 64 from 101 leaves us with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 64

On to step 6:
64 can be fit into 375 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 13315.0
Subtracting 320 from 375 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
If we divide 550 by 64, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 13315.8
If we subtract 512 from 550, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
64 can be fit into 380 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 13315.85
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.

On to step 9:
600 divided by 64 is 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 13315.859
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 64, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 13315.8593
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.

Moving on to step 11:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 13315.85937
Subtracting 448 from 480 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 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13315.859375
Subtract 320 from 320 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.

Step 13:
0 divided by 64 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13315.859375
The remainder is 0 after subtracting 0 from 0.
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 14:
0 divided by 64 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13315.859375
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 13315.859375, with a leftover of 0.0.
