Let's divide 12487910 by 11
The aim is to understand the frequency of 11 in 12487910.

Step 1:
1 divided by 11 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 11

Let's proceed to step 2:
11 can be fit into 12 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 11 from 12 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 11

Let's proceed to step 3:
When dividing 14 by 11, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 11 from 14 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 11

Moving on to step 4:
The number 11 fits into 38 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtract 33 from 38 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 11

On to step 5:
When dividing 57 by 11, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 1135.0
Deduct 55 from 57 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 11

Advancing to step 6:
29 divided by 11 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 11352.0
Subtracting 22 from 29 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 11

Moving on to step 7:
The number 11 fits into 71 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 113526.0
Deduct 66 from 71 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 11

Let's proceed to step 8:
When dividing 50 by 11, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1135264.0
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
11 goes into 60 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1135264.5
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 11, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1135264.54
If we subtract 44 from 50, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1135264.545
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
When dividing 50 by 11, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1135264.5454
Deduct 44 from 50 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
If we divide 60 by 11, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1135264.54545
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
If we divide 50 by 11, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 1135264.545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 15:
When dividing 60 by 11, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1135264.5454545
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
If we divide 50 by 11, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 1135264.54545454
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 1135264.54545454 and a remainder of 6e-09.
