We divide 64521 by 17
We want to figure out the number of times 64521 can be divided by 17.

Let's proceed to step 1:
6 divided by 17 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 17

On to step 2:
17 goes into 64 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 51 from 64 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 17

Moving on to step 3:
The number 17 fits into 135 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 119 from 135, we get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 17

On to step 4:
The number 17 fits into 162 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 379.0
Subtract 153 from 162 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 17

On to step 5:
If we divide 91 by 17, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 3795.0
If we subtract 85 from 91, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 6:
If we divide 60 by 17, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 3795.3
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
17 can be fit into 90 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3795.35
Deduct 85 from 90 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 17, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 3795.352
Deduct 34 from 50 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 17, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 3795.3529
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
If we divide 70 by 17, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3795.35294
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
When dividing 20 by 17, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 3795.352941
If we subtract 17 from 20, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
30 divided by 17 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 3795.3529411
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 3795.3529411 with a remaining 1.3e-07.
