Let's divide 31112782 by 909
The aim is to understand the frequency of 909 in 31112782.

Moving on to step 1:
3 divided by 909 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 909

On to step 2:
If we divide 31 by 909, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 909

On to step 3:
311 divided by 909 is 0 with a remainder of 311.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 311, we get 311.
Include the next digit (1) from the dividend after 311, then repeat: 3111 / 909

Moving on to step 4:
909 can be fit into 3111 3 times, resulting in a remainder of 384.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2727 away from 3111, we end up with 384.
Append the next digit (2) from the dividend to 384 and continue with: 3842 / 909

Advancing to step 5:
909 can be fit into 3842 4 times, resulting in a remainder of 206.
Write down 4 as next digit of the result. 
Result so far: 34.0
The remainder is 206 after subtracting 3636 from 3842.
Take the next digit (7) from the dividend and append it to 206, then repeat: 2067 / 909

Step 6:
The number 909 fits into 2067 2 times, leaving a remainder of 249.
Put 2 as the next digit of the answer. 
Result so far: 342.0
If we subtract 1818 from 2067, we get 249.
Bring next digit (8) of the dividend behind the 249 and repeat the process: 2498 / 909

On to step 7:
909 can be fit into 2498 2 times, resulting in a remainder of 680.
The number 2 becomes the next digit in our result. 
Result so far: 3422.0
Deduct 1818 from 2498 and we're left with 680.
Append the next digit (2) from the dividend to 680 and continue with: 6802 / 909

Moving on to step 8:
If we divide 6802 by 909, we get 7 and a remainder of 439.
Write down 7 as next digit of the result. 
Result so far: 34227.0
If we take 6363 away from 6802, we end up with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Step 9:
909 goes into 4390 4 times with a remainder of 754.
Put 4 as the next digit of the answer. 
Result so far: 34227.4
Subtracting 3636 from 4390 leaves us with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Moving on to step 10:
7540 divided by 909 is 8 with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 34227.48
If we take 7272 away from 7540, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 11:
909 can be fit into 2680 2 times, resulting in a remainder of 862.
Record the quotient 2 as the next digit in the result. 
Result so far: 34227.482
Subtract 1818 from 2680 to get 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

On to step 12:
If we divide 8620 by 909, we get 9 and a remainder of 439.
Record the quotient 9 as the next digit in the result. 
Result so far: 34227.4829
The remainder is 439 after subtracting 8181 from 8620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

On to step 13:
When dividing 4390 by 909, we get 4 with a remainder of 754.
The number 4 becomes the next digit in our result. 
Result so far: 34227.48294
If we subtract 3636 from 4390, we get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Going ahead to step 14:
909 can be fit into 7540 8 times, resulting in a remainder of 268.
Use 8 as the next digit of our solution. 
Result so far: 34227.482948
Subtracting 7272 from 7540 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 15:
2680 divided by 909 is 2 with a remainder of 862.
Record the quotient 2 as the next digit in the result. 
Result so far: 34227.4829482
If we take 1818 away from 2680, we end up with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

On to step 16:
909 can be fit into 8620 9 times, resulting in a remainder of 439.
Use 9 as the next digit of our solution. 
Result so far: 34227.48294829
Deduct 8181 from 8620 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Our division results in 34227.48294829 with a remaining 4.39e-07.
