Let's divide 51385015 by 165
We want to divide 51385015 by 165.

Going ahead to step 1:
When dividing 5 by 165, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 165

Let's proceed to step 2:
51 divided by 165 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 165

On to step 3:
If we divide 513 by 165, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 495 from 513, we get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 165

Step 4:
The number 165 fits into 188 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 165 from 188 and we're left with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 165

Let's proceed to step 5:
The number 165 fits into 235 1 times, leaving a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 311.0
If we take 165 away from 235, we end up with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 165

Going ahead to step 6:
700 divided by 165 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 3114.0
Subtract 660 from 700 to get 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 165

Advancing to step 7:
165 goes into 401 2 times with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 31142.0
If we take 330 away from 401, we end up with 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 165

Let's proceed to step 8:
715 divided by 165 is 4 with a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 311424.0
If we subtract 660 from 715, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
550 divided by 165 is 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 311424.3
If we subtract 495 from 550, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
If we divide 550 by 165, we get 3 and a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 311424.33
Subtracting 495 from 550 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 311424.33, and the remainder is 0.055.
