We're dividing 12413666 by 171 
We're looking to find how many times 171 goes into 12413666.

On to step 1:
If we divide 1 by 171, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 171

On to step 2:
When dividing 12 by 171, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 171

On to step 3:
171 can be fit into 124 0 times, resulting in a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Append the next digit (1) from the dividend to 124 and continue with: 1241 / 171

Going ahead to step 4:
When dividing 1241 by 171, we get 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 1197 from 1241 and we're left with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 171

Step 5:
171 goes into 443 2 times with a remainder of 101.
The next digit of our result is 2. 
Result so far: 72.0
If we take 342 away from 443, we end up with 101.
Include the next digit (6) from the dividend after 101, then repeat: 1016 / 171

Going ahead to step 6:
171 can be fit into 1016 5 times, resulting in a remainder of 161.
Put 5 as the next digit of the answer. 
Result so far: 725.0
Deduct 855 from 1016 and we're left with 161.
Bring next digit (6) of the dividend behind the 161 and repeat the process: 1616 / 171

Going ahead to step 7:
171 can be fit into 1616 9 times, resulting in a remainder of 77.
The next digit of our result is 9. 
Result so far: 7259.0
If we take 1539 away from 1616, we end up with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 171

Let's proceed to step 8:
If we divide 776 by 171, we get 4 and a remainder of 92.
The next digit of our result is 4. 
Result so far: 72594.0
Subtract 684 from 776 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
If we divide 920 by 171, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 72594.5
Subtract 855 from 920 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
When dividing 650 by 171, we get 3 with a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 72594.53
Deduct 513 from 650 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 11:
The number 171 fits into 1370 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 72594.538
Deduct 1368 from 1370 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
If we divide 20 by 171, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 72594.538
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
The number 171 fits into 200 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 72594.53801
Deduct 171 from 200 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 14:
When dividing 290 by 171, we get 1 with a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 72594.538011
The remainder is 119 after subtracting 171 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The final outcome is 72594.538011, with a leftover of 1.19e-05.
