We're dividing 686391 by 41 
The aim is to understand the frequency of 41 in 686391.

Moving on to step 1:
41 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 41

Advancing to step 2:
When dividing 68 by 41, we get 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 27 after subtracting 41 from 68.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 41

Let's proceed to step 3:
The number 41 fits into 276 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 246 from 276 leaves us with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 41

Advancing to step 4:
41 can be fit into 303 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 167.0
If we take 287 away from 303, we end up with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 41

Advancing to step 5:
169 divided by 41 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 1674.0
Deduct 164 from 169 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 41

Advancing to step 6:
The number 41 fits into 51 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 16741.0
The remainder is 10 after subtracting 41 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 41, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 16741.2
If we subtract 82 from 100, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 41 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 16741.24
Deduct 164 from 180 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
When dividing 160 by 41, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 16741.243
Deduct 123 from 160 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
41 can be fit into 370 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 16741.2439
The remainder is 1 after subtracting 369 from 370.
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 11:
If we divide 10 by 41, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 16741.2439
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.

Moving on to step 12:
41 can be fit into 100 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 16741.243902
If we subtract 82 from 100, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
When dividing 180 by 41, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 16741.2439024
If we take 164 away from 180, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
If we divide 160 by 41, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 16741.24390243
If we take 123 away from 160, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 16741.24390243 and a remainder of 3.7e-08.
