We're dividing 9911877 by 151 
The aim is to understand the frequency of 151 in 9911877.

Advancing to step 1:
151 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 151

Step 2:
151 goes into 99 0 times with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 151

Step 3:
If we divide 991 by 151, we get 6 and a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 906 from 991 leaves us with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 151

Moving on to step 4:
151 goes into 851 5 times with a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 755 from 851 leaves us with 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 151

Moving on to step 5:
When dividing 968 by 151, we get 6 with a remainder of 62.
The next digit of our result is 6. 
Result so far: 656.0
If we subtract 906 from 968, we get 62.
Include the next digit (7) from the dividend after 62, then repeat: 627 / 151

Going ahead to step 6:
627 divided by 151 is 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 6564.0
If we subtract 604 from 627, we get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 151

Step 7:
The number 151 fits into 237 1 times, leaving a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 65641.0
Subtract 151 from 237 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 8:
860 divided by 151 is 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 65641.5
Deduct 755 from 860 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 9:
When dividing 1050 by 151, we get 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 65641.56
The remainder is 144 after subtracting 906 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 10:
If we divide 1440 by 151, we get 9 and a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 65641.569
The remainder is 81 after subtracting 1359 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 11:
If we divide 810 by 151, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 65641.5695
If we subtract 755 from 810, we 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 12:
If we divide 550 by 151, we get 3 and a remainder of 97.
The next digit of our result is 3. 
Result so far: 65641.56953
If we take 453 away from 550, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 13:
The number 151 fits into 970 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 65641.569536
If we take 906 away from 970, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
The number 151 fits into 640 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 65641.5695364
The remainder is 36 after subtracting 604 from 640.
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 15:
151 can be fit into 360 2 times, resulting in a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 65641.56953642
Subtracting 302 from 360 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 65641.56953642 with a remainder of 5.8e-08.
