We look at the division of 69209621 by 149 
The aim is to understand the frequency of 149 in 69209621.

On to step 1:
If we divide 6 by 149, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 149

Step 2:
When dividing 69 by 149, we get 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 149

Step 3:
If we divide 692 by 149, we get 4 and a remainder of 96.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 596 from 692, we get 96.
Take the next digit (0) from the dividend and append it to 96, then repeat: 960 / 149

Step 4:
When dividing 960 by 149, we get 6 with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 894 from 960 leaves us with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 149

Going ahead to step 5:
When dividing 669 by 149, we get 4 with a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 464.0
If we subtract 596 from 669, we get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 149

Moving on to step 6:
When dividing 736 by 149, we get 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 4644.0
Subtracting 596 from 736 leaves us with 140.
Append the next digit (2) from the dividend to 140 and continue with: 1402 / 149

Let's proceed to step 7:
The number 149 fits into 1402 9 times, leaving a remainder of 61.
The next digit of our result is 9. 
Result so far: 46449.0
Deduct 1341 from 1402 and we're left with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 149

Going ahead to step 8:
149 can be fit into 611 4 times, resulting in a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 464494.0
Subtract 596 from 611 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
149 goes into 150 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 464494.1
If we take 149 away from 150, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
When dividing 10 by 149, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 464494.1
If we subtract 0 from 10, 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 11:
149 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 464494.1
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 464494.1 with a balance of 0.01.
