We divide 17150670 by 909
The aim is to understand the frequency of 909 in 17150670.

Going ahead to step 1:
If we divide 1 by 909, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 909

Step 2:
909 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 909

Step 3:
The number 909 fits into 171 0 times, leaving a remainder of 171.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 171 leaves us with 171.
Fetch the next digit (5) from the dividend, attach it to 171 and continue: 1715 / 909

Let's proceed to step 4:
When dividing 1715 by 909, we get 1 with a remainder of 806.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 806 after subtracting 909 from 1715.
Grab the next digit (0) from the dividend, add it to 806, then carry on: 8060 / 909

Advancing to step 5:
If we divide 8060 by 909, we get 8 and a remainder of 788.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 7272 from 8060, we get 788.
Take the next digit (6) from the dividend and append it to 788, then repeat: 7886 / 909

On to step 6:
If we divide 7886 by 909, we get 8 and a remainder of 614.
The next digit of our result is 8. 
Result so far: 188.0
Subtracting 7272 from 7886 leaves us with 614.
Grab the next digit (7) from the dividend, add it to 614, then carry on: 6147 / 909

Going ahead to step 7:
909 goes into 6147 6 times with a remainder of 693.
Record the quotient 6 as the next digit in the result. 
Result so far: 1886.0
If we take 5454 away from 6147, we end up with 693.
Fetch the next digit (0) from the dividend, attach it to 693 and continue: 6930 / 909

Going ahead to step 8:
If we divide 6930 by 909, we get 7 and a remainder of 567.
The next digit of our result is 7. 
Result so far: 18867.0
If we subtract 6363 from 6930, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

On to step 9:
The number 909 fits into 5670 6 times, leaving a remainder of 216.
Put 6 as the next digit of the answer. 
Result so far: 18867.6
If we take 5454 away from 5670, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
If we divide 2160 by 909, we get 2 and a remainder of 342.
The next digit of our result is 2. 
Result so far: 18867.62
If we take 1818 away from 2160, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 11:
If we divide 3420 by 909, we get 3 and a remainder of 693.
Write down 3 as next digit of the result. 
Result so far: 18867.623
If we subtract 2727 from 3420, we get 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Going ahead to step 12:
When dividing 6930 by 909, we get 7 with a remainder of 567.
Record the quotient 7 as the next digit in the result. 
Result so far: 18867.6237
If we take 6363 away from 6930, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 13:
909 goes into 5670 6 times with a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 18867.62376
If we subtract 5454 from 5670, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
909 goes into 2160 2 times with a remainder of 342.
Use 2 as the next digit of our solution. 
Result so far: 18867.623762
Subtracting 1818 from 2160 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 15:
909 can be fit into 3420 3 times, resulting in a remainder of 693.
Write down 3 as next digit of the result. 
Result so far: 18867.6237623
The remainder is 693 after subtracting 2727 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Going ahead to step 16:
The number 909 fits into 6930 7 times, leaving a remainder of 567.
The next digit of our result is 7. 
Result so far: 18867.62376237
If we subtract 6363 from 6930, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

After the division, we end up with 18867.62376237 and a remainder of 5.67e-07.
