We divide 42528135 by 109
The aim is to understand the frequency of 109 in 42528135.

Let's proceed to step 1:
When dividing 4 by 109, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 109

Advancing to step 2:
When dividing 42 by 109, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 109

On to step 3:
The number 109 fits into 425 3 times, leaving a remainder of 98.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 327 from 425, we get 98.
Bring next digit (2) of the dividend behind the 98 and repeat the process: 982 / 109

Step 4:
The number 109 fits into 982 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 1 after subtracting 981 from 982.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 109

On to step 5:
When dividing 18 by 109, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 109

Moving on to step 6:
109 can be fit into 181 1 times, resulting in a remainder of 72.
The next digit of our result is 1. 
Result so far: 3901.0
Subtract 109 from 181 to get 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 109

Let's proceed to step 7:
109 goes into 723 6 times with a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 39016.0
The remainder is 69 after subtracting 654 from 723.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 109

Let's proceed to step 8:
If we divide 695 by 109, we get 6 and a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 390166.0
Subtract 654 from 695 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
109 goes into 410 3 times with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 390166.3
If we take 327 away from 410, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 10:
The number 109 fits into 830 7 times, leaving a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 390166.37
If we take 763 away from 830, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
The number 109 fits into 670 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 390166.376
Deduct 654 from 670 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 109 is 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 390166.3761
Subtract 109 from 160 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 13:
The number 109 fits into 510 4 times, leaving a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 390166.37614
Subtracting 436 from 510 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
If we divide 740 by 109, we get 6 and a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 390166.376146
Deduct 654 from 740 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 15:
The number 109 fits into 860 7 times, leaving a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 390166.3761467
Subtract 763 from 860 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 16:
970 divided by 109 is 8 with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 390166.37614678
If we subtract 872 from 970, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

After the division, we end up with 390166.37614678 and a remainder of 9.8e-08.
