26473620 ÷ 159 
The aim is to understand the frequency of 159 in 26473620.

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
Subtract 0 from 2 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 159

Advancing to step 2:
The number 159 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 159

Advancing to step 3:
159 can be fit into 264 1 times, resulting in a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 159 from 264 leaves us with 105.
Bring next digit (7) of the dividend behind the 105 and repeat the process: 1057 / 159

Moving on to step 4:
If we divide 1057 by 159, we get 6 and a remainder of 103.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 103 after subtracting 954 from 1057.
Grab the next digit (3) from the dividend, add it to 103, then carry on: 1033 / 159

On to step 5:
The number 159 fits into 1033 6 times, leaving a remainder of 79.
The next digit of our result is 6. 
Result so far: 166.0
Subtracting 954 from 1033 leaves us with 79.
Bring next digit (6) of the dividend behind the 79 and repeat the process: 796 / 159

On to step 6:
When dividing 796 by 159, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1665.0
Deduct 795 from 796 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 159

Going ahead to step 7:
159 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 16650.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 159

Let's proceed to step 8:
The number 159 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 166500.0
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 9:
159 can be fit into 1200 7 times, resulting in a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 166500.7
The remainder is 87 after subtracting 1113 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 10:
The number 159 fits into 870 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 166500.75
Subtracting 795 from 870 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
750 divided by 159 is 4 with a remainder of 114.
Record the quotient 4 as the next digit in the result. 
Result so far: 166500.754
Subtracting 636 from 750 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 12:
The number 159 fits into 1140 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 166500.7547
Subtracting 1113 from 1140 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
When dividing 270 by 159, we get 1 with a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 166500.75471
Deduct 159 from 270 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 14:
When dividing 1110 by 159, we get 6 with a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 166500.754716
If we subtract 954 from 1110, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 15:
1560 divided by 159 is 9 with a remainder of 129.
The number 9 becomes the next digit in our result. 
Result so far: 166500.7547169
Deduct 1431 from 1560 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 16:
If we divide 1290 by 159, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 166500.75471698
If we take 1272 away from 1290, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 166500.75471698 with a remaining 1.8e-08.
