We look at the division of 42615486 by 909 
The aim is to understand the frequency of 909 in 42615486.

Going ahead to step 1:
When dividing 4 by 909, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 909

On to step 2:
The number 909 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 909

Going ahead to step 3:
When dividing 426 by 909, we get 0 with a remainder of 426.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 426, we end up with 426.
Bring next digit (1) of the dividend behind the 426 and repeat the process: 4261 / 909

Advancing to step 4:
909 can be fit into 4261 4 times, resulting in a remainder of 625.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3636 away from 4261, we end up with 625.
Append the next digit (5) from the dividend to 625 and continue with: 6255 / 909

Moving on to step 5:
If we divide 6255 by 909, we get 6 and a remainder of 801.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtract 5454 from 6255 to get 801.
Include the next digit (4) from the dividend after 801, then repeat: 8014 / 909

On to step 6:
The number 909 fits into 8014 8 times, leaving a remainder of 742.
Record the quotient 8 as the next digit in the result. 
Result so far: 468.0
If we subtract 7272 from 8014, we get 742.
Take the next digit (8) from the dividend and append it to 742, then repeat: 7428 / 909

Moving on to step 7:
7428 divided by 909 is 8 with a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 4688.0
If we take 7272 away from 7428, we end up with 156.
Take the next digit (6) from the dividend and append it to 156, then repeat: 1566 / 909

Advancing to step 8:
If we divide 1566 by 909, we get 1 and a remainder of 657.
Record the quotient 1 as the next digit in the result. 
Result so far: 46881.0
The remainder is 657 after subtracting 909 from 1566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Let's proceed to step 9:
The number 909 fits into 6570 7 times, leaving a remainder of 207.
Write down 7 as next digit of the result. 
Result so far: 46881.7
Subtract 6363 from 6570 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 10:
2070 divided by 909 is 2 with a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 46881.72
Subtract 1818 from 2070 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 11:
If we divide 2520 by 909, we get 2 and a remainder of 702.
Write down 2 as next digit of the result. 
Result so far: 46881.722
If we take 1818 away from 2520, we end up with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

In conclusion, the division gives 46881.722 with a balance of 0.0702.
