We're dividing 66500864 by 171 
Our goal is to divide 66500864 by 171.

On to step 1:
When dividing 6 by 171, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 171

Advancing to step 2:
171 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 171

Advancing to step 3:
If we divide 665 by 171, we get 3 and a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 513 away from 665, we end up with 152.
Take the next digit (0) from the dividend and append it to 152, then repeat: 1520 / 171

On to step 4:
171 can be fit into 1520 8 times, resulting in a remainder of 152.
The next digit of our result is 8. 
Result so far: 38.0
The remainder is 152 after subtracting 1368 from 1520.
Take the next digit (0) from the dividend and append it to 152, then repeat: 1520 / 171

Going ahead to step 5:
171 can be fit into 1520 8 times, resulting in a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 388.0
Subtract 1368 from 1520 to get 152.
Append the next digit (8) from the dividend to 152 and continue with: 1528 / 171

Advancing to step 6:
The number 171 fits into 1528 8 times, leaving a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 3888.0
The remainder is 160 after subtracting 1368 from 1528.
Append the next digit (6) from the dividend to 160 and continue with: 1606 / 171

Going ahead to step 7:
171 goes into 1606 9 times with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 38889.0
Subtract 1539 from 1606 to get 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 171

Step 8:
171 goes into 674 3 times with a remainder of 161.
Put 3 as the next digit of the answer. 
Result so far: 388893.0
Subtracting 513 from 674 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 9:
When dividing 1610 by 171, we get 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 388893.9
If we take 1539 away from 1610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
The number 171 fits into 710 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 388893.94
Deduct 684 from 710 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
260 divided by 171 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 388893.941
The remainder is 89 after subtracting 171 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 12:
171 goes into 890 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 388893.9415
Subtracting 855 from 890 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
350 divided by 171 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 388893.94152
Subtract 342 from 350 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
The number 171 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 388893.94152
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
171 can be fit into 800 4 times, resulting in a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 388893.9415204
If we subtract 684 from 800, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 16:
When dividing 1160 by 171, we get 6 with a remainder of 134.
Use 6 as the next digit of our solution. 
Result so far: 388893.94152046
If we subtract 1026 from 1160, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The quotient of the division is 388893.94152046, and the remainder is 1.34e-07.
