We look at the division of 171187 by 64 
We want to figure out the number of times 171187 can be divided by 64.

Advancing to step 1:
1 divided by 64 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 64

Step 2:
When dividing 17 by 64, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 64

Advancing to step 3:
The number 64 fits into 171 2 times, leaving a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 128 from 171 to get 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 64

On to step 4:
The number 64 fits into 431 6 times, leaving a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 384 from 431 and we're left with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 64

Step 5:
The number 64 fits into 478 7 times, leaving a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 267.0
If we subtract 448 from 478, we get 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 64

On to step 6:
307 divided by 64 is 4 with a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 2674.0
If we subtract 256 from 307, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
The number 64 fits into 510 7 times, leaving a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 2674.7
Deduct 448 from 510 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
When dividing 620 by 64, we get 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 2674.79
If we take 576 away from 620, we end up 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.
Record the quotient 6 as the next digit in the result. 
Result so far: 2674.796
If we take 384 away from 440, 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.

Moving on to step 10:
64 can be fit into 560 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 2674.7968
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.

Advancing to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 2674.79687
Subtracting 448 from 480 leaves us 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.

Going ahead to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2674.796875
Subtract 320 from 320 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 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2674.796875
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.
Use 0 as the next digit of our solution. 
Result so far: 2674.796875
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.

After the division, we end up with 2674.796875 and a remainder of 0.0.
