Let's divide 861888 by 64
We want to divide 861888 by 64.

Advancing to step 1:
64 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 64

On to step 2:
The number 64 fits into 86 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 64 away from 86, we end up with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 64

Moving on to step 3:
If we divide 221 by 64, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 192 from 221 to get 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 64

Going ahead to step 4:
If we divide 298 by 64, we get 4 and a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Subtract 256 from 298 to get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 64

Advancing to step 5:
The number 64 fits into 428 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 1346.0
Subtracting 384 from 428 leaves us with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 64

Going ahead to step 6:
64 can be fit into 448 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 13467.0
If we subtract 448 from 448, 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.

Let's proceed to step 7:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 13467.0
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.

On to step 8:
64 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13467.0
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.

Our division results in 13467.0 with a remaining 0.0.
