We're dividing 18678506 by 171 
We want to divide 18678506 by 171.

Let's proceed to step 1:
171 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 171

Step 2:
171 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 171

Let's proceed to step 3:
If we divide 186 by 171, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 171 from 186 to get 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 171

Step 4:
If we divide 157 by 171, we get 0 and a remainder of 157.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 157 to get 157.
Include the next digit (8) from the dividend after 157, then repeat: 1578 / 171

Advancing to step 5:
When dividing 1578 by 171, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we take 1539 away from 1578, we end up with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 171

Moving on to step 6:
The number 171 fits into 395 2 times, leaving a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 1092.0
If we subtract 342 from 395, we get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 171

On to step 7:
When dividing 530 by 171, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 10923.0
The remainder is 17 after subtracting 513 from 530.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 171

Step 8:
When dividing 176 by 171, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 109231.0
The remainder is 5 after subtracting 171 from 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 171 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 109231.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
500 divided by 171 is 2 with a remainder of 158.
Put 2 as the next digit of the answer. 
Result so far: 109231.02
If we take 342 away from 500, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 11:
171 goes into 1580 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 109231.029
Deduct 1539 from 1580 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 12:
The number 171 fits into 410 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 109231.0292
Subtract 342 from 410 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
If we divide 680 by 171, we get 3 and a remainder of 167.
Record the quotient 3 as the next digit in the result. 
Result so far: 109231.02923
Subtract 513 from 680 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 14:
If we divide 1670 by 171, we get 9 and a remainder of 131.
The number 9 becomes the next digit in our result. 
Result so far: 109231.029239
If we take 1539 away from 1670, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 15:
171 goes into 1310 7 times with a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 109231.0292397
Deduct 1197 from 1310 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 16:
The number 171 fits into 1130 6 times, leaving a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 109231.02923976
Subtract 1026 from 1130 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 109231.02923976 with a remainder of 1.04e-07.
