We look at the division of 75281810 by 149 
The aim is to understand the frequency of 149 in 75281810.

Advancing to step 1:
When dividing 7 by 149, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 149

Advancing to step 2:
75 divided by 149 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (2) from the dividend after 75, then repeat: 752 / 149

Advancing to step 3:
The number 149 fits into 752 5 times, leaving a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 745 from 752 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 149

Advancing to step 4:
When dividing 78 by 149, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 50.0
Subtract 0 from 78 to get 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 149

Let's proceed to step 5:
781 divided by 149 is 5 with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 505.0
The remainder is 36 after subtracting 745 from 781.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 149

Let's proceed to step 6:
149 can be fit into 368 2 times, resulting in a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 5052.0
If we take 298 away from 368, we end up with 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 149

Advancing to step 7:
If we divide 701 by 149, we get 4 and a remainder of 105.
The number 4 becomes the next digit in our result. 
Result so far: 50524.0
The remainder is 105 after subtracting 596 from 701.
Append the next digit (0) from the dividend to 105 and continue with: 1050 / 149

Step 8:
1050 divided by 149 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 505247.0
Deduct 1043 from 1050 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
If we divide 70 by 149, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 505247.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 149 is 4 with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 505247.04
If we take 596 away from 700, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 11:
If we divide 1040 by 149, we get 6 and a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 505247.046
The remainder is 146 after subtracting 894 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 12:
The number 149 fits into 1460 9 times, leaving a remainder of 119.
The number 9 becomes the next digit in our result. 
Result so far: 505247.0469
If we take 1341 away from 1460, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 13:
1190 divided by 149 is 7 with a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 505247.04697
If we subtract 1043 from 1190, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 14:
If we divide 1470 by 149, we get 9 and a remainder of 129.
The next digit of our result is 9. 
Result so far: 505247.046979
Deduct 1341 from 1470 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.

Step 15:
If we divide 1290 by 149, we get 8 and a remainder of 98.
The next digit of our result is 8. 
Result so far: 505247.0469798
Deduct 1192 from 1290 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 16:
If we divide 980 by 149, we get 6 and a remainder of 86.
The next digit of our result is 6. 
Result so far: 505247.04697986
The remainder is 86 after subtracting 894 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 505247.04697986, and the remainder is 8.6e-08.
