71605854 ÷ 149 
The aim is to understand the frequency of 149 in 71605854.

Advancing to step 1:
The number 149 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 149

Let's proceed to step 2:
149 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 149

Going ahead to step 3:
716 divided by 149 is 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 596 away from 716, we end up with 120.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 149

Going ahead to step 4:
149 goes into 1200 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 1192 from 1200 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 149

Going ahead to step 5:
When dividing 85 by 149, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 480.0
Subtract 0 from 85 to get 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 149

Advancing to step 6:
When dividing 858 by 149, we get 5 with a remainder of 113.
The next digit of our result is 5. 
Result so far: 4805.0
Subtracting 745 from 858 leaves us with 113.
Fetch the next digit (5) from the dividend, attach it to 113 and continue: 1135 / 149

On to step 7:
149 can be fit into 1135 7 times, resulting in a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 48057.0
The remainder is 92 after subtracting 1043 from 1135.
Include the next digit (4) from the dividend after 92, then repeat: 924 / 149

Step 8:
When dividing 924 by 149, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 480576.0
Subtracting 894 from 924 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 149, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 480576.2
Subtracting 298 from 300 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
20 divided by 149 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 480576.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 149, we get 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 480576.201
Deduct 149 from 200 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
510 divided by 149 is 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 480576.2013
Subtracting 447 from 510 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 13:
630 divided by 149 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 480576.20134
If we subtract 596 from 630, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
340 divided by 149 is 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 480576.201342
If we subtract 298 from 340, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 15:
If we divide 420 by 149, we get 2 and a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 480576.2013422
Deduct 298 from 420 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

After the division, we end up with 480576.2013422 and a remainder of 1.22e-06.
