Let's divide 35988759 by 159
The aim is to understand the frequency of 159 in 35988759.

Going ahead to step 1:
159 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 159

Going ahead to step 2:
159 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 159

Moving on to step 3:
359 divided by 159 is 2 with a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 318 from 359, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 159

On to step 4:
159 goes into 418 2 times with a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 100 after subtracting 318 from 418.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 159

Step 5:
The number 159 fits into 1008 6 times, leaving a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 226.0
If we take 954 away from 1008, we end up with 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 159

On to step 6:
547 divided by 159 is 3 with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 2263.0
The remainder is 70 after subtracting 477 from 547.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 159

Step 7:
The number 159 fits into 705 4 times, leaving a remainder of 69.
The next digit of our result is 4. 
Result so far: 22634.0
If we take 636 away from 705, we end up with 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 159

Step 8:
699 divided by 159 is 4 with a remainder of 63.
The next digit of our result is 4. 
Result so far: 226344.0
Subtract 636 from 699 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
159 goes into 630 3 times with a remainder of 153.
The number 3 becomes the next digit in our result. 
Result so far: 226344.3
The remainder is 153 after subtracting 477 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 10:
159 goes into 1530 9 times with a remainder of 99.
Write down 9 as next digit of the result. 
Result so far: 226344.39
Subtract 1431 from 1530 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 11:
159 can be fit into 990 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 226344.396
Deduct 954 from 990 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
159 can be fit into 360 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 226344.3962
Deduct 318 from 360 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
When dividing 420 by 159, we get 2 with a remainder of 102.
The next digit of our result is 2. 
Result so far: 226344.39622
Subtract 318 from 420 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 226344.39622, with a leftover of 0.000102.
