52984391 ÷ 159 
The aim is to understand the frequency of 159 in 52984391.

Let's proceed to step 1:
5 divided by 159 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 159

Moving on to step 2:
159 goes into 52 0 times with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 159

Advancing to step 3:
159 goes into 529 3 times with a remainder of 52.
The next digit of our result is 3. 
Result so far: 3.0
If we take 477 away from 529, we end up with 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 159

Going ahead to step 4:
159 goes into 528 3 times with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 477 away from 528, we end up with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 159

Going ahead to step 5:
When dividing 514 by 159, we get 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 333.0
The remainder is 37 after subtracting 477 from 514.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 159

Advancing to step 6:
The number 159 fits into 373 2 times, leaving a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 3332.0
Deduct 318 from 373 and we're left with 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 159

Going ahead to step 7:
559 divided by 159 is 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 33323.0
The remainder is 82 after subtracting 477 from 559.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 159

Going ahead to step 8:
The number 159 fits into 821 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 333235.0
Subtract 795 from 821 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
If we divide 260 by 159, we get 1 and a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 333235.1
Deduct 159 from 260 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 10:
159 can be fit into 1010 6 times, resulting in a remainder of 56.
The next digit of our result is 6. 
Result so far: 333235.16
If we subtract 954 from 1010, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
If we divide 560 by 159, we get 3 and a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 333235.163
If we take 477 away from 560, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
159 goes into 830 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 333235.1635
The remainder is 35 after subtracting 795 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
The number 159 fits into 350 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 333235.16352
Subtract 318 from 350 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
159 goes into 320 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 333235.163522
Subtract 318 from 320 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 333235.163522 with a remaining 2e-07.
