Let's divide 858666 by 64
Let's see how many times 64 fits into 858666.

Step 1:
64 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 64

On to step 2:
85 divided by 64 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 64 from 85 and we're left with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 64

Moving on to step 3:
If we divide 218 by 64, we get 3 and a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 192 away from 218, we end up with 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 64

Moving on to step 4:
266 divided by 64 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 10 after subtracting 256 from 266.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 64

Moving on to step 5:
64 goes into 106 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1341.0
If we take 64 away from 106, we end up with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 64

Let's proceed to step 6:
426 divided by 64 is 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 13416.0
Subtract 384 from 426 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
64 can be fit into 420 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 13416.6
The remainder is 36 after subtracting 384 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
64 can be fit into 360 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 13416.65
If we subtract 320 from 360, 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 9:
64 goes into 400 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 13416.656
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.

Advancing to step 10:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 13416.6562
If we subtract 128 from 160, we 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:
320 divided by 64 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13416.65625
If we subtract 320 from 320, 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 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13416.65625
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.

Going ahead to step 13:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13416.65625
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 13416.65625, and the remainder is 0.0.
