860469 divided by 64 
We're looking to find how many times 64 goes into 860469.

Moving on to step 1:
The number 64 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 64

Let's proceed to step 2:
64 goes into 86 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 22 after subtracting 64 from 86.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 64

Let's proceed to step 3:
When dividing 220 by 64, we get 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 192 from 220 and we're left with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 64

Moving on to step 4:
The number 64 fits into 284 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 134.0
Deduct 256 from 284 and we're left with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 64

Step 5:
The number 64 fits into 286 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 1344.0
If we take 256 away from 286, we end up with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 64

Advancing to step 6:
The number 64 fits into 309 4 times, leaving a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 13444.0
The remainder is 53 after subtracting 256 from 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 64 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 13444.8
If we subtract 512 from 530, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
The number 64 fits into 180 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 13444.82
If we subtract 128 from 180, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
When dividing 520 by 64, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 13444.828
Subtracting 512 from 520 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 64 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 13444.8281
If we take 64 away from 80, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 13444.82812
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.

Advancing to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 13444.828125
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 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13444.828125
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.

Moving on to step 14:
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: 13444.828125
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.

The final outcome is 13444.828125, with a leftover of 0.0.
