We divide 51219913 by 165
We're looking to find how many times 165 goes into 51219913.

Moving on to step 1:
If we divide 5 by 165, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 165

Advancing to step 2:
If we divide 51 by 165, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 165

Advancing to step 3:
165 goes into 512 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 495 away from 512, we end up with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 165

On to step 4:
If we divide 171 by 165, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 165 from 171, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 165

Let's proceed to step 5:
The number 165 fits into 69 0 times, leaving a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 310.0
Subtract 0 from 69 to get 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 165

Step 6:
When dividing 699 by 165, we get 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 3104.0
Deduct 660 from 699 and we're left with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 165

Advancing to step 7:
If we divide 391 by 165, we get 2 and a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 31042.0
Subtract 330 from 391 to get 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 165

Step 8:
The number 165 fits into 613 3 times, leaving a remainder of 118.
Put 3 as the next digit of the answer. 
Result so far: 310423.0
Deduct 495 from 613 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 9:
If we divide 1180 by 165, we get 7 and a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 310423.7
If we subtract 1155 from 1180, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
When dividing 250 by 165, we get 1 with a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 310423.71
Deduct 165 from 250 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 11:
If we divide 850 by 165, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 310423.715
The remainder is 25 after subtracting 825 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
If we divide 250 by 165, we get 1 and a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 310423.7151
If we subtract 165 from 250, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 13:
The number 165 fits into 850 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 310423.71515
Deduct 825 from 850 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
250 divided by 165 is 1 with a remainder of 85.
The next digit of our result is 1. 
Result so far: 310423.715151
If we take 165 away from 250, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
If we divide 850 by 165, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 310423.7151515
Deduct 825 from 850 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 16:
When dividing 250 by 165, we get 1 with a remainder of 85.
The next digit of our result is 1. 
Result so far: 310423.71515151
If we subtract 165 from 250, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 310423.71515151, with a leftover of 8.5e-08.
