We divide 148961 by 11
The aim is to understand the frequency of 11 in 148961.

Moving on to step 1:
11 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 11

Moving on to step 2:
14 divided by 11 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 11 from 14 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 11

Advancing to step 3:
If we divide 38 by 11, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 33 from 38 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 11

Let's proceed to step 4:
When dividing 59 by 11, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Deduct 55 from 59 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 11

Going ahead to step 5:
46 divided by 11 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1354.0
If we subtract 44 from 46, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 11

Advancing to step 6:
When dividing 21 by 11, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 13541.0
Subtract 11 from 21 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 11, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 13541.9
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
10 divided by 11 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13541.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 11, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 13541.909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
When dividing 10 by 11, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13541.909
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
100 divided by 11 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 13541.90909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
When dividing 10 by 11, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 13541.90909
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
The number 11 fits into 100 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 13541.9090909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
11 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13541.9090909
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 13541.9090909, with a leftover of 1e-08.
