We look at the division of 52018467 by 149 
The aim is to understand the frequency of 149 in 52018467.

Moving on to step 1:
The number 149 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 149

Going ahead to step 2:
149 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 149

On to step 3:
The number 149 fits into 520 3 times, leaving a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 73 after subtracting 447 from 520.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 149

Going ahead to step 4:
149 can be fit into 731 4 times, resulting in a remainder of 135.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 596 from 731 leaves us with 135.
Include the next digit (8) from the dividend after 135, then repeat: 1358 / 149

Let's proceed to step 5:
149 goes into 1358 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 349.0
If we take 1341 away from 1358, we end up with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 149

Let's proceed to step 6:
The number 149 fits into 174 1 times, leaving a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 3491.0
Subtracting 149 from 174 leaves us with 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 149

Let's proceed to step 7:
149 goes into 256 1 times with a remainder of 107.
Put 1 as the next digit of the answer. 
Result so far: 34911.0
If we take 149 away from 256, we end up with 107.
Append the next digit (7) from the dividend to 107 and continue with: 1077 / 149

On to step 8:
149 goes into 1077 7 times with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 349117.0
If we take 1043 away from 1077, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
The number 149 fits into 340 2 times, leaving a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 349117.2
If we take 298 away from 340, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
420 divided by 149 is 2 with a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 349117.22
Subtract 298 from 420 to get 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 349117.22 and a remainder of 0.122.
