Let's divide 81493459 by 149
The aim is to understand the frequency of 149 in 81493459.

Going ahead to step 1:
The number 149 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 149

Let's proceed to step 2:
149 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 149

Going ahead to step 3:
If we divide 814 by 149, we get 5 and a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 745 from 814 leaves us with 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 149

Step 4:
When dividing 699 by 149, we get 4 with a remainder of 103.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 596 away from 699, we end up with 103.
Append the next digit (3) from the dividend to 103 and continue with: 1033 / 149

On to step 5:
If we divide 1033 by 149, we get 6 and a remainder of 139.
Put 6 as the next digit of the answer. 
Result so far: 546.0
Subtracting 894 from 1033 leaves us with 139.
Fetch the next digit (4) from the dividend, attach it to 139 and continue: 1394 / 149

Going ahead to step 6:
When dividing 1394 by 149, we get 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 5469.0
If we take 1341 away from 1394, we end up with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 149

Moving on to step 7:
535 divided by 149 is 3 with a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 54693.0
Subtracting 447 from 535 leaves us with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 149

Advancing to step 8:
149 goes into 889 5 times with a remainder of 144.
The next digit of our result is 5. 
Result so far: 546935.0
The remainder is 144 after subtracting 745 from 889.
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 9:
When dividing 1440 by 149, we get 9 with a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 546935.9
Deduct 1341 from 1440 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 10:
If we divide 990 by 149, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 546935.96
If we take 894 away from 990, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
149 can be fit into 960 6 times, resulting in a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 546935.966
The remainder is 66 after subtracting 894 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 546935.966 with a remainder of 0.0066.
