Let's divide 690421 by 41
The aim is to understand the frequency of 41 in 690421.

Step 1:
41 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 41

Let's proceed to step 2:
When dividing 69 by 41, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 41 away from 69, we end up with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 41

Let's proceed to step 3:
The number 41 fits into 280 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 246 from 280, we get 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 41

Going ahead to step 4:
If we divide 344 by 41, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 168.0
Deduct 328 from 344 and we're left with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 41

Moving on to step 5:
41 can be fit into 162 3 times, resulting in a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 1683.0
The remainder is 39 after subtracting 123 from 162.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 41

Moving on to step 6:
When dividing 391 by 41, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 16839.0
Subtracting 369 from 391 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
When dividing 220 by 41, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 16839.5
Subtract 205 from 220 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
150 divided by 41 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 16839.53
If we take 123 away from 150, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
If we divide 270 by 41, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 16839.536
Subtracting 246 from 270 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
41 goes into 240 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 16839.5365
If we take 205 away from 240, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
The number 41 fits into 350 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 16839.53658
If we subtract 328 from 350, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
41 goes into 220 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 16839.536585
Subtracting 205 from 220 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
150 divided by 41 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 16839.5365853
Subtract 123 from 150 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
270 divided by 41 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 16839.53658536
If we subtract 246 from 270, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 16839.53658536 with a remainder of 2.4e-08.
