We're dividing 66163050 by 171 
Let's see how many times 171 fits into 66163050.

Moving on to step 1:
The number 171 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 171

Step 2:
171 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 171

Moving on to step 3:
When dividing 661 by 171, we get 3 with a remainder of 148.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 513 from 661 leaves us with 148.
Bring next digit (6) of the dividend behind the 148 and repeat the process: 1486 / 171

Going ahead to step 4:
When dividing 1486 by 171, we get 8 with a remainder of 118.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 1368 from 1486 leaves us with 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 171

Going ahead to step 5:
1183 divided by 171 is 6 with a remainder of 157.
Put 6 as the next digit of the answer. 
Result so far: 386.0
Subtract 1026 from 1183 to get 157.
Take the next digit (0) from the dividend and append it to 157, then repeat: 1570 / 171

Let's proceed to step 6:
If we divide 1570 by 171, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 3869.0
Deduct 1539 from 1570 and we're left with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 171

Going ahead to step 7:
171 can be fit into 315 1 times, resulting in a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 38691.0
If we take 171 away from 315, we end up with 144.
Append the next digit (0) from the dividend to 144 and continue with: 1440 / 171

Going ahead to step 8:
171 can be fit into 1440 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 386918.0
Subtracting 1368 from 1440 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
720 divided by 171 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 386918.4
The remainder is 36 after subtracting 684 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
If we divide 360 by 171, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 386918.42
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
171 goes into 180 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 386918.421
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
171 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 386918.421
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
If we divide 900 by 171, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 386918.42105
Subtract 855 from 900 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
The number 171 fits into 450 2 times, leaving a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 386918.421052
If we subtract 342 from 450, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 15:
If we divide 1080 by 171, we get 6 and a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 386918.4210526
If we take 1026 away from 1080, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 16:
The number 171 fits into 540 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 386918.42105263
The remainder is 27 after subtracting 513 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 386918.42105263 with a balance of 2.7e-08.
