We look at the division of 872486 by 64 
We're looking to find how many times 64 goes into 872486.

On to step 1:
When dividing 8 by 64, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 64

Advancing to step 2:
64 can be fit into 87 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 23 after subtracting 64 from 87.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 64

Going ahead to step 3:
64 goes into 232 3 times with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 192 from 232 to get 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 64

Let's proceed to step 4:
If we divide 404 by 64, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we take 384 away from 404, we end up with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 64

Step 5:
208 divided by 64 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 1363.0
The remainder is 16 after subtracting 192 from 208.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 64

Let's proceed to step 6:
64 goes into 166 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 13632.0
Subtract 128 from 166 to 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 7:
64 can be fit into 380 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 13632.5
Subtracting 320 from 380 leaves us 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.

Let's proceed to step 8:
The number 64 fits into 600 9 times, leaving a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 13632.59
Subtract 576 from 600 to 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.

Going ahead to step 9:
64 can be fit into 240 3 times, resulting in a remainder of 48.
The next digit of our result is 3. 
Result so far: 13632.593
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 13632.5937
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.

Advancing to step 11:
When dividing 320 by 64, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13632.59375
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 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13632.59375
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.

Going ahead to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13632.59375
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.

The final outcome is 13632.59375, with a leftover of 0.0.
