87388098 ÷ 165 
Our goal is to divide 87388098 by 165.

Let's proceed to step 1:
The number 165 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 165

Let's proceed to step 2:
The number 165 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (3) from the dividend after 87, then repeat: 873 / 165

Step 3:
The number 165 fits into 873 5 times, leaving a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 825 from 873 and we're left with 48.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 165

Step 4:
When dividing 488 by 165, we get 2 with a remainder of 158.
The next digit of our result is 2. 
Result so far: 52.0
If we subtract 330 from 488, we get 158.
Grab the next digit (8) from the dividend, add it to 158, then carry on: 1588 / 165

On to step 5:
When dividing 1588 by 165, we get 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 529.0
If we subtract 1485 from 1588, we get 103.
Include the next digit (0) from the dividend after 103, then repeat: 1030 / 165

Let's proceed to step 6:
If we divide 1030 by 165, we get 6 and a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 5296.0
If we take 990 away from 1030, we end up with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 165

Advancing to step 7:
409 divided by 165 is 2 with a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 52962.0
If we take 330 away from 409, we end up with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 165

Let's proceed to step 8:
165 can be fit into 798 4 times, resulting in a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 529624.0
If we subtract 660 from 798, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
165 goes into 1380 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 529624.8
Subtract 1320 from 1380 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
When dividing 600 by 165, we get 3 with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 529624.83
If we subtract 495 from 600, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 11:
When dividing 1050 by 165, we get 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 529624.836
If we subtract 990 from 1050, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
165 can be fit into 600 3 times, resulting in a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 529624.8363
If we subtract 495 from 600, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 13:
1050 divided by 165 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 529624.83636
If we subtract 990 from 1050, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
165 can be fit into 600 3 times, resulting in a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 529624.836363
Subtracting 495 from 600 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 15:
165 can be fit into 1050 6 times, resulting in a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 529624.8363636
Deduct 990 from 1050 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
165 can be fit into 600 3 times, resulting in a remainder of 105.
The next digit of our result is 3. 
Result so far: 529624.83636363
Subtracting 495 from 600 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 529624.83636363 with a remainder of 1.05e-07.
