We're dividing 537874 by 11 
The aim is to understand the frequency of 11 in 537874.

On to step 1:
11 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 11

Going ahead to step 2:
The number 11 fits into 53 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 44 from 53, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 11

Moving on to step 3:
The number 11 fits into 97 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 88 from 97 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 11

Going ahead to step 4:
11 goes into 98 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 488.0
If we take 88 away from 98, we end up with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 11

Advancing to step 5:
107 divided by 11 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4889.0
Subtract 99 from 107 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 11

Let's proceed to step 6:
11 goes into 84 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 48897.0
Deduct 77 from 84 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.

Moving on to step 7:
11 goes into 70 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 48897.6
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.

On to step 8:
11 goes into 40 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 48897.63
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.

Advancing to step 9:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 48897.636
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.

Step 10:
11 can be fit into 40 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 48897.6363
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 11:
70 divided by 11 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 48897.63636
Subtract 66 from 70 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.

Moving on to step 12:
If we divide 40 by 11, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 48897.636363
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.

Advancing to step 13:
If we divide 70 by 11, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 48897.6363636
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.

Going ahead to step 14:
If we divide 40 by 11, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 48897.63636363
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.

The final result is 48897.63636363 with a remainder of 7e-09.
