We're dividing 98786655 by 155 
The aim is to understand the frequency of 155 in 98786655.

Going ahead to step 1:
When dividing 9 by 155, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 155

Step 2:
98 divided by 155 is 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 155

Let's proceed to step 3:
When dividing 987 by 155, we get 6 with a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 930 from 987 leaves us with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 155

Moving on to step 4:
155 goes into 578 3 times with a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 465 away from 578, we end up with 113.
Fetch the next digit (6) from the dividend, attach it to 113 and continue: 1136 / 155

Step 5:
1136 divided by 155 is 7 with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 637.0
The remainder is 51 after subtracting 1085 from 1136.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 155

Let's proceed to step 6:
155 can be fit into 516 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 6373.0
If we subtract 465 from 516, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 155

Going ahead to step 7:
When dividing 515 by 155, we get 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 63733.0
The remainder is 50 after subtracting 465 from 515.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 155

Step 8:
155 can be fit into 505 3 times, resulting in a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 637333.0
Subtracting 465 from 505 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 155, we get 2 with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 637333.2
The remainder is 90 after subtracting 310 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
When dividing 900 by 155, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 637333.25
Deduct 775 from 900 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
If we divide 1250 by 155, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 637333.258
If we subtract 1240 from 1250, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
155 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 637333.258
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
When dividing 1000 by 155, we get 6 with a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 637333.25806
The remainder is 70 after subtracting 930 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
When dividing 700 by 155, we get 4 with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 637333.258064
If we subtract 620 from 700, 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.

On to step 15:
155 can be fit into 800 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 637333.2580645
Subtracting 775 from 800 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 16:
250 divided by 155 is 1 with a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 637333.25806451
Subtracting 155 from 250 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

In conclusion, the division gives 637333.25806451 with a balance of 9.5e-08.
