We're dividing 770286 by 64 
We want to figure out the number of times 770286 can be divided by 64.

Let's proceed to step 1:
64 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 64

Let's proceed to step 2:
77 divided by 64 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 64 away from 77, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 64

Let's proceed to step 3:
If we divide 130 by 64, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 128 from 130 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 64

Step 4:
64 goes into 22 0 times with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 64

On to step 5:
The number 64 fits into 228 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 1203.0
Subtract 192 from 228 to get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 64

Going ahead to step 6:
The number 64 fits into 366 5 times, leaving a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 12035.0
If we subtract 320 from 366, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
The number 64 fits into 460 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 12035.7
If we take 448 away from 460, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 64, we get 1 with a remainder of 56.
The next digit of our result is 1. 
Result so far: 12035.71
The remainder is 56 after subtracting 64 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
64 goes into 560 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 12035.718
Subtracting 512 from 560 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
64 goes into 480 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 12035.7187
Subtract 448 from 480 to get 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 11:
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: 12035.71875
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.

Step 12:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12035.71875
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.

On to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12035.71875
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 quotient of the division is 12035.71875, and the remainder is 0.0.
