We divide 10415057 by 909
The aim is to understand the frequency of 909 in 10415057.

Advancing to step 1:
1 divided by 909 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 909

Advancing to step 2:
When dividing 10 by 909, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 909

Moving on to step 3:
The number 909 fits into 104 0 times, leaving a remainder of 104.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 104, we get 104.
Include the next digit (1) from the dividend after 104, then repeat: 1041 / 909

Let's proceed to step 4:
When dividing 1041 by 909, we get 1 with a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 132 after subtracting 909 from 1041.
Fetch the next digit (5) from the dividend, attach it to 132 and continue: 1325 / 909

Moving on to step 5:
909 goes into 1325 1 times with a remainder of 416.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 909 from 1325, we get 416.
Append the next digit (0) from the dividend to 416 and continue with: 4160 / 909

Step 6:
909 goes into 4160 4 times with a remainder of 524.
The next digit of our result is 4. 
Result so far: 114.0
The remainder is 524 after subtracting 3636 from 4160.
Include the next digit (5) from the dividend after 524, then repeat: 5245 / 909

Moving on to step 7:
909 can be fit into 5245 5 times, resulting in a remainder of 700.
Put 5 as the next digit of the answer. 
Result so far: 1145.0
Subtract 4545 from 5245 to get 700.
Include the next digit (7) from the dividend after 700, then repeat: 7007 / 909

Going ahead to step 8:
When dividing 7007 by 909, we get 7 with a remainder of 644.
The number 7 becomes the next digit in our result. 
Result so far: 11457.0
If we take 6363 away from 7007, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 9:
6440 divided by 909 is 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 11457.7
Deduct 6363 from 6440 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 10:
If we divide 770 by 909, we get 0 and a remainder of 770.
Record the quotient 0 as the next digit in the result. 
Result so far: 11457.7
Subtract 0 from 770 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 11:
7700 divided by 909 is 8 with a remainder of 428.
Put 8 as the next digit of the answer. 
Result so far: 11457.708
Subtracting 7272 from 7700 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 12:
When dividing 4280 by 909, we get 4 with a remainder of 644.
Record the quotient 4 as the next digit in the result. 
Result so far: 11457.7084
The remainder is 644 after subtracting 3636 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 13:
If we divide 6440 by 909, we get 7 and a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 11457.70847
The remainder is 77 after subtracting 6363 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
If we divide 770 by 909, we get 0 and a remainder of 770.
Use 0 as the next digit of our solution. 
Result so far: 11457.70847
Deduct 0 from 770 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 15:
When dividing 7700 by 909, we get 8 with a remainder of 428.
Use 8 as the next digit of our solution. 
Result so far: 11457.7084708
Subtracting 7272 from 7700 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 16:
4280 divided by 909 is 4 with a remainder of 644.
Put 4 as the next digit of the answer. 
Result so far: 11457.70847084
Subtract 3636 from 4280 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

After the division, we end up with 11457.70847084 and a remainder of 6.44e-07.
