We look at the division of 23565561 by 165 
We want to figure out the number of times 23565561 can be divided by 165.

Going ahead to step 1:
165 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 165

Step 2:
The number 165 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 165

Advancing to step 3:
When dividing 235 by 165, we get 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 165 from 235, we get 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 165

Moving on to step 4:
When dividing 706 by 165, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 46 after subtracting 660 from 706.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 165

Advancing to step 5:
When dividing 465 by 165, we get 2 with a remainder of 135.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 330 from 465 to get 135.
Take the next digit (5) from the dividend and append it to 135, then repeat: 1355 / 165

Advancing to step 6:
The number 165 fits into 1355 8 times, leaving a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 1428.0
Subtracting 1320 from 1355 leaves us with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 165

On to step 7:
When dividing 356 by 165, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 14282.0
If we take 330 away from 356, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 165

On to step 8:
When dividing 261 by 165, we get 1 with a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 142821.0
If we subtract 165 from 261, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
The number 165 fits into 960 5 times, leaving a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 142821.5
Subtracting 825 from 960 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
The number 165 fits into 1350 8 times, leaving a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 142821.58
Subtracting 1320 from 1350 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 165, we get 1 with a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 142821.581
Subtracting 165 from 300 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 12:
165 can be fit into 1350 8 times, resulting in a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 142821.5818
Subtract 1320 from 1350 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
When dividing 300 by 165, we get 1 with a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 142821.58181
Subtracting 165 from 300 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 14:
165 goes into 1350 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 142821.581818
Subtract 1320 from 1350 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 15:
165 can be fit into 300 1 times, resulting in a remainder of 135.
The next digit of our result is 1. 
Result so far: 142821.5818181
The remainder is 135 after subtracting 165 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 16:
165 goes into 1350 8 times with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 142821.58181818
If we subtract 1320 from 1350, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 142821.58181818, with a leftover of 3e-08.
