We divide 161854 by 11
The aim is to understand the frequency of 11 in 161854.

On to step 1:
The number 11 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 11

On to step 2:
16 divided by 11 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 11 from 16, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 11

Going ahead to step 3:
11 can be fit into 51 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 44 from 51 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 11

Let's proceed to step 4:
The number 11 fits into 78 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 147.0
Deduct 77 from 78 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 11

Going ahead to step 5:
When dividing 15 by 11, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1471.0
If we subtract 11 from 15, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 11

On to step 6:
If we divide 44 by 11, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14714.0
If we take 44 away from 44, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
11 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14714.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 11 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14714.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 14714.0 with a remaining 0.0.
