20505459 divided by 165 
Our goal is to divide 20505459 by 165.

On to step 1:
2 divided by 165 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 165

On to step 2:
If we divide 20 by 165, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 165

Advancing to step 3:
205 divided by 165 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 40 after subtracting 165 from 205.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 165

Let's proceed to step 4:
165 can be fit into 400 2 times, resulting in a remainder of 70.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 70 after subtracting 330 from 400.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 165

Going ahead to step 5:
When dividing 705 by 165, we get 4 with a remainder of 45.
The next digit of our result is 4. 
Result so far: 124.0
Deduct 660 from 705 and we're left with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 165

Moving on to step 6:
165 can be fit into 454 2 times, resulting in a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 1242.0
Deduct 330 from 454 and we're left with 124.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 165

On to step 7:
The number 165 fits into 1245 7 times, leaving a remainder of 90.
Put 7 as the next digit of the answer. 
Result so far: 12427.0
Subtracting 1155 from 1245 leaves us with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 165

Step 8:
If we divide 909 by 165, we get 5 and a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 124275.0
Subtracting 825 from 909 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
840 divided by 165 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 124275.5
If we take 825 away from 840, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
165 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 124275.5
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
165 can be fit into 1500 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 124275.509
Deduct 1485 from 1500 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
165 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 124275.509
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
The number 165 fits into 1500 9 times, leaving a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 124275.50909
Subtract 1485 from 1500 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
When dividing 150 by 165, we get 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 124275.50909
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 15:
165 can be fit into 1500 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 124275.5090909
Deduct 1485 from 1500 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 16:
When dividing 150 by 165, we get 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 124275.5090909
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 124275.5090909 with a balance of 1.5e-07.
