We look at the division of 10687209 by 171 
We want to figure out the number of times 10687209 can be divided by 171.

Advancing to step 1:
If we divide 1 by 171, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 171

Advancing to step 2:
When dividing 10 by 171, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 171

Advancing to step 3:
The number 171 fits into 106 0 times, leaving a remainder of 106.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 106, we end up with 106.
Fetch the next digit (8) from the dividend, attach it to 106 and continue: 1068 / 171

Step 4:
When dividing 1068 by 171, we get 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 42 after subtracting 1026 from 1068.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 171

Going ahead to step 5:
171 can be fit into 427 2 times, resulting in a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Deduct 342 from 427 and we're left with 85.
Take the next digit (2) from the dividend and append it to 85, then repeat: 852 / 171

Going ahead to step 6:
When dividing 852 by 171, we get 4 with a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 624.0
If we take 684 away from 852, we end up with 168.
Include the next digit (0) from the dividend after 168, then repeat: 1680 / 171

Advancing to step 7:
If we divide 1680 by 171, we get 9 and a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 6249.0
Subtract 1539 from 1680 to get 141.
Grab the next digit (9) from the dividend, add it to 141, then carry on: 1419 / 171

Going ahead to step 8:
171 goes into 1419 8 times with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 62498.0
If we subtract 1368 from 1419, 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 9:
The number 171 fits into 510 2 times, leaving a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 62498.2
If we subtract 342 from 510, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 10:
When dividing 1680 by 171, we get 9 with a remainder of 141.
Write down 9 as next digit of the result. 
Result so far: 62498.29
If we subtract 1539 from 1680, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 11:
171 goes into 1410 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 62498.298
Deduct 1368 from 1410 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
171 goes into 420 2 times with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 62498.2982
The remainder is 78 after subtracting 342 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
When dividing 780 by 171, we get 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 62498.29824
If we take 684 away from 780, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
960 divided by 171 is 5 with a remainder of 105.
The next digit of our result is 5. 
Result so far: 62498.298245
Subtract 855 from 960 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 15:
171 goes into 1050 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 62498.2982456
If we take 1026 away from 1050, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 16:
When dividing 240 by 171, we get 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 62498.29824561
Subtracting 171 from 240 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 62498.29824561 and a remainder of 6.9e-08.
