53839375 ÷ 165 
The aim is to understand the frequency of 165 in 53839375.

Going ahead to step 1:
When dividing 5 by 165, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 165

On to step 2:
165 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 165

Moving on to step 3:
The number 165 fits into 538 3 times, leaving a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 495 away from 538, we end up with 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 165

Going ahead to step 4:
When dividing 433 by 165, we get 2 with a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 32.0
The remainder is 103 after subtracting 330 from 433.
Append the next digit (9) from the dividend to 103 and continue with: 1039 / 165

Moving on to step 5:
165 goes into 1039 6 times with a remainder of 49.
The next digit of our result is 6. 
Result so far: 326.0
If we take 990 away from 1039, we end up with 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 165

On to step 6:
493 divided by 165 is 2 with a remainder of 163.
Record the quotient 2 as the next digit in the result. 
Result so far: 3262.0
Subtracting 330 from 493 leaves us with 163.
Grab the next digit (7) from the dividend, add it to 163, then carry on: 1637 / 165

On to step 7:
If we divide 1637 by 165, we get 9 and a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 32629.0
Deduct 1485 from 1637 and we're left with 152.
Grab the next digit (5) from the dividend, add it to 152, then carry on: 1525 / 165

Let's proceed to step 8:
If we divide 1525 by 165, we get 9 and a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 326299.0
Deduct 1485 from 1525 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 165 fits into 400 2 times, leaving a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 326299.2
Subtract 330 from 400 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
165 goes into 700 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 326299.24
If we take 660 away from 700, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 165, we get 2 and a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 326299.242
If we take 330 away from 400, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
165 can be fit into 700 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 326299.2424
Subtract 660 from 700 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
If we divide 400 by 165, we get 2 and a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 326299.24242
Subtracting 330 from 400 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
165 goes into 700 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 326299.242424
Subtracting 660 from 700 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
165 can be fit into 400 2 times, resulting in a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 326299.2424242
Subtract 330 from 400 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
If we divide 700 by 165, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 326299.24242424
Subtract 660 from 700 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 326299.24242424 with a remaining 4e-08.
