171579 ÷ 64 
We're looking to find how many times 64 goes into 171579.

Step 1:
64 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 64

Moving on to step 2:
64 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 64

Step 3:
When dividing 171 by 64, we get 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 128 from 171 and we're left with 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 64

Moving on to step 4:
64 goes into 435 6 times with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 384 from 435 leaves us with 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 64

Step 5:
The number 64 fits into 517 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 268.0
Subtract 512 from 517 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 64

Let's proceed to step 6:
If we divide 59 by 64, we get 0 and a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 2680.0
If we subtract 0 from 59, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
The number 64 fits into 590 9 times, leaving a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 2680.9
The remainder is 14 after subtracting 576 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 64, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2680.92
If we take 128 away from 140, we end up 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.

Moving on to step 9:
If we divide 120 by 64, we get 1 and a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 2680.921
If we take 64 away from 120, we end up 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.

Advancing to step 10:
When dividing 560 by 64, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 2680.9218
If we subtract 512 from 560, we 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.

Moving on to step 11:
64 goes into 480 7 times with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 2680.92187
Deduct 448 from 480 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.

Advancing to step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2680.921875
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:
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: 2680.921875
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.

Going ahead to step 14:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2680.921875
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.

The final outcome is 2680.921875, with a leftover of 0.0.
