We look at the division of 803385 by 64 
We want to figure out the number of times 803385 can be divided by 64.

Moving on to step 1:
The number 64 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 64

Moving on to step 2:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 64 from 80, we get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 64

Moving on to step 3:
When dividing 163 by 64, we get 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 128 from 163 to get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 64

Moving on to step 4:
64 goes into 353 5 times with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we take 320 away from 353, we end up with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 64

Let's proceed to step 5:
The number 64 fits into 338 5 times, leaving a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
The remainder is 18 after subtracting 320 from 338.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 64

Advancing to step 6:
The number 64 fits into 185 2 times, leaving a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 12552.0
Subtract 128 from 185 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
If we divide 570 by 64, we get 8 and a remainder of 58.
The next digit of our result is 8. 
Result so far: 12552.8
Subtracting 512 from 570 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
If we divide 580 by 64, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 12552.89
Subtracting 576 from 580 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
64 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12552.89
If we subtract 0 from 40, we get 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 10:
If we divide 400 by 64, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 12552.8906
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
64 goes into 160 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 12552.89062
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12552.890625
Deduct 320 from 320 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.

On to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12552.890625
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.

Step 14:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12552.890625
Subtracting 0 from 0 leaves us 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 12552.890625, with a leftover of 0.0.
