We look at the division of 26851207 by 155 
The aim is to understand the frequency of 155 in 26851207.

Going ahead to step 1:
2 divided by 155 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 155

Moving on to step 2:
When dividing 26 by 155, we get 0 with 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.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 155

Moving on to step 3:
268 divided by 155 is 1 with a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 155 from 268 leaves us with 113.
Bring next digit (5) of the dividend behind the 113 and repeat the process: 1135 / 155

Let's proceed to step 4:
155 goes into 1135 7 times with a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 1085 from 1135 leaves us with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 155

Let's proceed to step 5:
155 goes into 501 3 times with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 173.0
Deduct 465 from 501 and we're left with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 155

On to step 6:
155 can be fit into 362 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 1732.0
If we subtract 310 from 362, we get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 155

Advancing to step 7:
155 goes into 520 3 times with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 17323.0
Subtracting 465 from 520 leaves us with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 155

Advancing to step 8:
557 divided by 155 is 3 with a remainder of 92.
The next digit of our result is 3. 
Result so far: 173233.0
If we take 465 away from 557, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
920 divided by 155 is 5 with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 173233.5
If we subtract 775 from 920, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 10:
155 goes into 1450 9 times with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 173233.59
Subtract 1395 from 1450 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
550 divided by 155 is 3 with a remainder of 85.
The next digit of our result is 3. 
Result so far: 173233.593
Subtracting 465 from 550 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
The number 155 fits into 850 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 173233.5935
If we subtract 775 from 850, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
155 can be fit into 750 4 times, resulting in a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 173233.59354
If we take 620 away from 750, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
1300 divided by 155 is 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 173233.593548
Subtract 1240 from 1300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
If we divide 600 by 155, we get 3 and a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 173233.5935483
Subtracting 465 from 600 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 16:
If we divide 1350 by 155, we get 8 and a remainder of 110.
Write down 8 as next digit of the result. 
Result so far: 173233.59354838
If we take 1240 away from 1350, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 173233.59354838 with a balance of 1.1e-07.
