53809945 divided by 165 
We want to figure out the number of times 53809945 can be divided by 165.

Advancing to step 1:
5 divided by 165 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 165

Step 2:
53 divided by 165 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 165

Step 3:
When dividing 538 by 165, we get 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 43 after subtracting 495 from 538.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 165

On to step 4:
165 can be fit into 430 2 times, resulting in a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 330 from 430, we get 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 165

Advancing to step 5:
165 goes into 1009 6 times with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 326.0
If we subtract 990 from 1009, we get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 165

Going ahead to step 6:
165 can be fit into 199 1 times, resulting in a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 3261.0
Subtracting 165 from 199 leaves us with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 165

Advancing to step 7:
165 goes into 344 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 32612.0
Subtracting 330 from 344 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 165

Step 8:
If we divide 145 by 165, we get 0 and a remainder of 145.
Use 0 as the next digit of our solution. 
Result so far: 326120.0
If we subtract 0 from 145, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
The number 165 fits into 1450 8 times, leaving a remainder of 130.
The next digit of our result is 8. 
Result so far: 326120.8
If we take 1320 away from 1450, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
165 goes into 1300 7 times with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 326120.87
Subtracting 1155 from 1300 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 11:
165 goes into 1450 8 times with a remainder of 130.
Record the quotient 8 as the next digit in the result. 
Result so far: 326120.878
The remainder is 130 after subtracting 1320 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
1300 divided by 165 is 7 with a remainder of 145.
Write down 7 as next digit of the result. 
Result so far: 326120.8787
If we subtract 1155 from 1300, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 13:
1450 divided by 165 is 8 with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 326120.87878
Deduct 1320 from 1450 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
When dividing 1300 by 165, we get 7 with a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 326120.878787
If we take 1155 away from 1300, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 15:
If we divide 1450 by 165, we get 8 and a remainder of 130.
Use 8 as the next digit of our solution. 
Result so far: 326120.8787878
If we subtract 1320 from 1450, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
The number 165 fits into 1300 7 times, leaving a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 326120.87878787
Subtracting 1155 from 1300 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

In conclusion, the division gives 326120.87878787 with a balance of 1.45e-07.
