We look at the division of 128459 by 64 
Let's see how many times 64 fits into 128459.

Let's proceed to step 1:
The number 64 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 64

Advancing to step 2:
If we divide 12 by 64, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 64

On to step 3:
128 divided by 64 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 128 from 128, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 64

Step 4:
The number 64 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 64

On to step 5:
When dividing 45 by 64, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 200.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 64

Moving on to step 6:
459 divided by 64 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 2007.0
Deduct 448 from 459 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
64 can be fit into 110 1 times, resulting in a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 2007.1
The remainder is 46 after subtracting 64 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
64 can be fit into 460 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 2007.17
Subtracting 448 from 460 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
64 can be fit into 120 1 times, resulting in a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 2007.171
The remainder is 56 after subtracting 64 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
When dividing 560 by 64, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 2007.1718
Subtracting 512 from 560 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 2007.17187
Subtract 448 from 480 to 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 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2007.171875
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.

Advancing to step 13:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2007.171875
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.

Advancing 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: 2007.171875
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 quotient of the division is 2007.171875, and the remainder is 0.0.
