We're dividing 41525541 by 820 
The aim is to understand the frequency of 820 in 41525541.

Moving on to step 1:
The number 820 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 820

Moving on to step 2:
If we divide 41 by 820, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 820

Step 3:
If we divide 415 by 820, we get 0 and a remainder of 415.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 415, we end up with 415.
Fetch the next digit (2) from the dividend, attach it to 415 and continue: 4152 / 820

Step 4:
If we divide 4152 by 820, we get 5 and a remainder of 52.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4100 from 4152, we get 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 820

Let's proceed to step 5:
If we divide 525 by 820, we get 0 and a remainder of 525.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 525 leaves us with 525.
Fetch the next digit (5) from the dividend, attach it to 525 and continue: 5255 / 820

Step 6:
820 goes into 5255 6 times with a remainder of 335.
Record the quotient 6 as the next digit in the result. 
Result so far: 506.0
Subtract 4920 from 5255 to get 335.
Take the next digit (4) from the dividend and append it to 335, then repeat: 3354 / 820

On to step 7:
When dividing 3354 by 820, we get 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 5064.0
Subtracting 3280 from 3354 leaves us with 74.
Take the next digit (1) from the dividend and append it to 74, then repeat: 741 / 820

Let's proceed to step 8:
When dividing 741 by 820, we get 0 with a remainder of 741.
Write down 0 as next digit of the result. 
Result so far: 50640.0
Deduct 0 from 741 and we're left with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Advancing to step 9:
If we divide 7410 by 820, we get 9 and a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 50640.9
Deduct 7380 from 7410 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 820, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 50640.9
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
The number 820 fits into 3000 3 times, leaving a remainder of 540.
Put 3 as the next digit of the answer. 
Result so far: 50640.903
Subtract 2460 from 3000 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 12:
820 can be fit into 5400 6 times, resulting in a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 50640.9036
If we subtract 4920 from 5400, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
4800 divided by 820 is 5 with a remainder of 700.
Record the quotient 5 as the next digit in the result. 
Result so far: 50640.90365
Deduct 4100 from 4800 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 14:
The number 820 fits into 7000 8 times, leaving a remainder of 440.
The number 8 becomes the next digit in our result. 
Result so far: 50640.903658
Deduct 6560 from 7000 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 15:
820 goes into 4400 5 times with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 50640.9036585
If we subtract 4100 from 4400, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 16:
If we divide 3000 by 820, we get 3 and a remainder of 540.
Use 3 as the next digit of our solution. 
Result so far: 50640.90365853
Deduct 2460 from 3000 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final outcome is 50640.90365853, with a leftover of 5.4e-07.
