87273102 divided by 11 
The aim is to understand the frequency of 11 in 87273102.

On to step 1:
11 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 11

On to step 2:
When dividing 87 by 11, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 77 from 87 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 11

Going ahead to step 3:
If we divide 102 by 11, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 3 after subtracting 99 from 102.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 11

Advancing to step 4:
11 goes into 37 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 793.0
Subtracting 33 from 37 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 11

On to step 5:
11 can be fit into 43 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 7933.0
If we subtract 33 from 43, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 11

Going ahead to step 6:
11 can be fit into 101 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 79339.0
Subtract 99 from 101 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 11

Advancing to step 7:
When dividing 20 by 11, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 793391.0
Subtracting 11 from 20 leaves us with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 11

Let's proceed to step 8:
The number 11 fits into 92 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7933918.0
Subtract 88 from 92 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 11 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 7933918.3
Subtracting 33 from 40 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
If we divide 70 by 11, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 7933918.36
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
40 divided by 11 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 7933918.363
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
If we divide 70 by 11, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7933918.3636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
11 can be fit into 40 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 7933918.36363
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
When dividing 70 by 11, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7933918.363636
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
If we divide 40 by 11, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 7933918.3636363
If we subtract 33 from 40, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 16:
If we divide 70 by 11, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 7933918.36363636
Subtracting 66 from 70 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 7933918.36363636, and the remainder is 4e-09.
