We're dividing 31592374 by 109 
The aim is to understand the frequency of 109 in 31592374.

Going ahead to step 1:
109 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 109

Advancing to step 2:
When dividing 31 by 109, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 109

Step 3:
109 can be fit into 315 2 times, resulting in a remainder of 97.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 218 from 315 to get 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 109

Advancing to step 4:
979 divided by 109 is 8 with a remainder of 107.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 107 after subtracting 872 from 979.
Fetch the next digit (2) from the dividend, attach it to 107 and continue: 1072 / 109

Step 5:
109 goes into 1072 9 times with a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 289.0
If we take 981 away from 1072, we end up with 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 109

Step 6:
109 can be fit into 913 8 times, resulting in a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 2898.0
The remainder is 41 after subtracting 872 from 913.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 109

Moving on to step 7:
The number 109 fits into 417 3 times, leaving a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 28983.0
If we take 327 away from 417, we end up with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 109

Advancing to step 8:
If we divide 904 by 109, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 289838.0
If we subtract 872 from 904, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
When dividing 320 by 109, we get 2 with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 289838.2
Deduct 218 from 320 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
If we divide 1020 by 109, we get 9 and a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 289838.29
Subtracting 981 from 1020 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
If we divide 390 by 109, we get 3 and a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 289838.293
If we subtract 327 from 390, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
When dividing 630 by 109, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 289838.2935
The remainder is 85 after subtracting 545 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
109 goes into 850 7 times with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 289838.29357
If we take 763 away from 850, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 14:
109 goes into 870 7 times with a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 289838.293577
The remainder is 107 after subtracting 763 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final result is 289838.293577 with a remainder of 1.07e-05.
