51082180 ÷ 165 
We want to figure out the number of times 51082180 can be divided by 165.

On to step 1:
The number 165 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 165

Step 2:
51 divided by 165 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 165

Let's proceed to step 3:
165 can be fit into 510 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 15 after subtracting 495 from 510.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 165

Moving on to step 4:
If we divide 158 by 165, we get 0 and a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 158 after subtracting 0 from 158.
Include the next digit (2) from the dividend after 158, then repeat: 1582 / 165

On to step 5:
If we divide 1582 by 165, we get 9 and a remainder of 97.
Record the quotient 9 as the next digit in the result. 
Result so far: 309.0
The remainder is 97 after subtracting 1485 from 1582.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 165

On to step 6:
165 can be fit into 971 5 times, resulting in a remainder of 146.
The next digit of our result is 5. 
Result so far: 3095.0
If we take 825 away from 971, we end up with 146.
Include the next digit (8) from the dividend after 146, then repeat: 1468 / 165

Let's proceed to step 7:
If we divide 1468 by 165, we get 8 and a remainder of 148.
The next digit of our result is 8. 
Result so far: 30958.0
The remainder is 148 after subtracting 1320 from 1468.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 165

Moving on to step 8:
165 can be fit into 1480 8 times, resulting in a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 309588.0
Subtracting 1320 from 1480 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
165 goes into 1600 9 times with a remainder of 115.
The number 9 becomes the next digit in our result. 
Result so far: 309588.9
If we take 1485 away from 1600, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 10:
165 can be fit into 1150 6 times, resulting in a remainder of 160.
The next digit of our result is 6. 
Result so far: 309588.96
Deduct 990 from 1150 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
1600 divided by 165 is 9 with a remainder of 115.
The next digit of our result is 9. 
Result so far: 309588.969
The remainder is 115 after subtracting 1485 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 12:
The number 165 fits into 1150 6 times, leaving a remainder of 160.
The next digit of our result is 6. 
Result so far: 309588.9696
Subtract 990 from 1150 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
The number 165 fits into 1600 9 times, leaving a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 309588.96969
If we take 1485 away from 1600, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 14:
1150 divided by 165 is 6 with a remainder of 160.
The next digit of our result is 6. 
Result so far: 309588.969696
Deduct 990 from 1150 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
1600 divided by 165 is 9 with a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 309588.9696969
Deduct 1485 from 1600 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 16:
165 can be fit into 1150 6 times, resulting in a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 309588.96969696
If we take 990 away from 1150, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 309588.96969696 with a balance of 1.6e-07.
