We look at the division of 879891 by 64 
Let's see how many times 64 fits into 879891.

On to step 1:
When dividing 8 by 64, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 64

On to step 2:
64 goes into 87 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 64 away from 87, we end up with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 64

Let's proceed to step 3:
64 can be fit into 239 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 192 from 239 and we're left with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 64

On to step 4:
64 goes into 478 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 448 from 478 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 64

Advancing to step 5:
64 can be fit into 309 4 times, resulting in a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
Subtract 256 from 309 to get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 64

Going ahead to step 6:
64 can be fit into 531 8 times, resulting in a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 13748.0
If we subtract 512 from 531, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
64 can be fit into 190 2 times, resulting in a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 13748.2
The remainder is 62 after subtracting 128 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
64 can be fit into 620 9 times, resulting in a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 13748.29
Deduct 576 from 620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
440 divided by 64 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 13748.296
Subtracting 384 from 440 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
64 can be fit into 560 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 13748.2968
Subtract 512 from 560 to get 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 11:
480 divided by 64 is 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 13748.29687
If we subtract 448 from 480, 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.

Step 12:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13748.296875
Subtracting 320 from 320 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.

Moving on to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13748.296875
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.

Going ahead to step 14:
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: 13748.296875
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.

The final result is 13748.296875 with a remainder of 0.0.
