We look at the division of 27067691 by 159 
The aim is to understand the frequency of 159 in 27067691.

Step 1:
If we divide 2 by 159, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 159

Step 2:
27 divided by 159 is 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 159

Step 3:
The number 159 fits into 270 1 times, leaving a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 111 after subtracting 159 from 270.
Fetch the next digit (6) from the dividend, attach it to 111 and continue: 1116 / 159

On to step 4:
If we divide 1116 by 159, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 1113 from 1116 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 159

Going ahead to step 5:
If we divide 37 by 159, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 159

On to step 6:
If we divide 376 by 159, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 1702.0
Subtracting 318 from 376 leaves us with 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 159

Going ahead to step 7:
589 divided by 159 is 3 with a remainder of 112.
The next digit of our result is 3. 
Result so far: 17023.0
If we subtract 477 from 589, we get 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 159

Going ahead to step 8:
1121 divided by 159 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 170237.0
Deduct 1113 from 1121 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 159 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 170237.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 159 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 170237.05
If we take 795 away from 800, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
The number 159 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 170237.05
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
500 divided by 159 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 170237.0503
Deduct 477 from 500 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
230 divided by 159 is 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 170237.05031
Subtracting 159 from 230 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 14:
The number 159 fits into 710 4 times, leaving a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 170237.050314
Subtracting 636 from 710 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 15:
The number 159 fits into 740 4 times, leaving a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 170237.0503144
If we subtract 636 from 740, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 170237.0503144, and the remainder is 1.04e-06.
