Let's divide 10961266 by 515
The aim is to understand the frequency of 515 in 10961266.

Moving on to step 1:
515 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 515

Step 2:
10 divided by 515 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 515

Advancing to step 3:
515 goes into 109 0 times with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 109 to get 109.
Take the next digit (6) from the dividend and append it to 109, then repeat: 1096 / 515

Advancing to step 4:
515 goes into 1096 2 times with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 66 after subtracting 1030 from 1096.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 515

Going ahead to step 5:
515 can be fit into 661 1 times, resulting in a remainder of 146.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 515 from 661 leaves us with 146.
Bring next digit (2) of the dividend behind the 146 and repeat the process: 1462 / 515

Advancing to step 6:
1462 divided by 515 is 2 with a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 212.0
If we subtract 1030 from 1462, we get 432.
Fetch the next digit (6) from the dividend, attach it to 432 and continue: 4326 / 515

Going ahead to step 7:
The number 515 fits into 4326 8 times, leaving a remainder of 206.
The number 8 becomes the next digit in our result. 
Result so far: 2128.0
Deduct 4120 from 4326 and we're left with 206.
Include the next digit (6) from the dividend after 206, then repeat: 2066 / 515

Let's proceed to step 8:
When dividing 2066 by 515, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 21284.0
The remainder is 6 after subtracting 2060 from 2066.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 515, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 21284.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
600 divided by 515 is 1 with a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 21284.01
The remainder is 85 after subtracting 515 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
The number 515 fits into 850 1 times, leaving a remainder of 335.
Write down 1 as next digit of the result. 
Result so far: 21284.011
Deduct 515 from 850 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The quotient of the division is 21284.011, and the remainder is 0.0335.
