We're dividing 89728104 by 64 
Let's see how many times 64 fits into 89728104.

Advancing to step 1:
8 divided by 64 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 64

On to step 2:
If we divide 89 by 64, we get 1 and a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 64 from 89 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 64

Moving on to step 3:
When dividing 257 by 64, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 1 after subtracting 256 from 257.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 64

Advancing to step 4:
12 divided by 64 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 140.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 64

Let's proceed to step 5:
The number 64 fits into 128 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1402.0
The remainder is 0 after subtracting 128 from 128.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 64

Let's proceed to step 6:
When dividing 1 by 64, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 14020.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 64

Step 7:
64 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 140200.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 64

Let's proceed to step 8:
104 divided by 64 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1402001.0
The remainder is 40 after subtracting 64 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 64, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1402001.6
If we subtract 384 from 400, we get 16.
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:
The number 64 fits into 160 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 1402001.62
Deduct 128 from 160 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.

Let's proceed to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1402001.625
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.

Step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1402001.625
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.

On to step 13:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1402001.625
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 1402001.625 with a remainder of 0.0.
