61276531 divided by 909 
The aim is to understand the frequency of 909 in 61276531.

Let's proceed to step 1:
909 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 909

Moving on to step 2:
909 goes into 61 0 times with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 909

Step 3:
When dividing 612 by 909, we get 0 with a remainder of 612.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 612 and we're left with 612.
Bring next digit (7) of the dividend behind the 612 and repeat the process: 6127 / 909

Going ahead to step 4:
The number 909 fits into 6127 6 times, leaving a remainder of 673.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 5454 from 6127 to get 673.
Fetch the next digit (6) from the dividend, attach it to 673 and continue: 6736 / 909

Step 5:
If we divide 6736 by 909, we get 7 and a remainder of 373.
Write down 7 as next digit of the result. 
Result so far: 67.0
The remainder is 373 after subtracting 6363 from 6736.
Include the next digit (5) from the dividend after 373, then repeat: 3735 / 909

Step 6:
3735 divided by 909 is 4 with a remainder of 99.
Record the quotient 4 as the next digit in the result. 
Result so far: 674.0
The remainder is 99 after subtracting 3636 from 3735.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 909

Going ahead to step 7:
The number 909 fits into 993 1 times, leaving a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 6741.0
The remainder is 84 after subtracting 909 from 993.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 909

On to step 8:
841 divided by 909 is 0 with a remainder of 841.
Write down 0 as next digit of the result. 
Result so far: 67410.0
Deduct 0 from 841 and we're left with 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Step 9:
If we divide 8410 by 909, we get 9 and a remainder of 229.
The next digit of our result is 9. 
Result so far: 67410.9
Subtracting 8181 from 8410 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 10:
909 can be fit into 2290 2 times, resulting in a remainder of 472.
The number 2 becomes the next digit in our result. 
Result so far: 67410.92
If we take 1818 away from 2290, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 11:
4720 divided by 909 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 67410.925
If we subtract 4545 from 4720, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 12:
If we divide 1750 by 909, we get 1 and a remainder of 841.
Write down 1 as next digit of the result. 
Result so far: 67410.9251
The remainder is 841 after subtracting 909 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Advancing to step 13:
If we divide 8410 by 909, we get 9 and a remainder of 229.
Put 9 as the next digit of the answer. 
Result so far: 67410.92519
The remainder is 229 after subtracting 8181 from 8410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 14:
If we divide 2290 by 909, we get 2 and a remainder of 472.
The next digit of our result is 2. 
Result so far: 67410.925192
Subtract 1818 from 2290 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 15:
If we divide 4720 by 909, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 67410.9251925
If we take 4545 away from 4720, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 16:
909 can be fit into 1750 1 times, resulting in a remainder of 841.
Write down 1 as next digit of the result. 
Result so far: 67410.92519251
The remainder is 841 after subtracting 909 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

The final result is 67410.92519251 with a remainder of 8.41e-07.
