17621475 divided by 109 
The aim is to understand the frequency of 109 in 17621475.

On to step 1:
109 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 109

Moving on to step 2:
109 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 109

Step 3:
When dividing 176 by 109, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 109 from 176, we get 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 109

Going ahead to step 4:
672 divided by 109 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 654 from 672, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 109

Going ahead to step 5:
If we divide 181 by 109, we get 1 and a remainder of 72.
The next digit of our result is 1. 
Result so far: 161.0
The remainder is 72 after subtracting 109 from 181.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 109

Let's proceed to step 6:
When dividing 724 by 109, we get 6 with a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 1616.0
If we subtract 654 from 724, we get 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 109

On to step 7:
707 divided by 109 is 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 16166.0
The remainder is 53 after subtracting 654 from 707.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 109

Going ahead to step 8:
109 can be fit into 535 4 times, resulting in a remainder of 99.
Put 4 as the next digit of the answer. 
Result so far: 161664.0
Subtracting 436 from 535 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
If we divide 990 by 109, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 161664.9
Subtract 981 from 990 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
When dividing 90 by 109, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 161664.9
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
109 can be fit into 900 8 times, resulting in a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 161664.908
Subtracting 872 from 900 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
280 divided by 109 is 2 with a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 161664.9082
If we subtract 218 from 280, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
620 divided by 109 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 161664.90825
The remainder is 75 after subtracting 545 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
750 divided by 109 is 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 161664.908256
If we take 654 away from 750, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 15:
109 goes into 960 8 times with a remainder of 88.
The next digit of our result is 8. 
Result so far: 161664.9082568
Deduct 872 from 960 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 16:
109 can be fit into 880 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 161664.90825688
The remainder is 8 after subtracting 872 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 161664.90825688, and the remainder is 8e-09.
