We're dividing 3060941 by 521 
The aim is to understand the frequency of 521 in 3060941.

Moving on to step 1:
521 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 521

Moving on to step 2:
30 divided by 521 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 521

On to step 3:
521 goes into 306 0 times with a remainder of 306.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Include the next digit (0) from the dividend after 306, then repeat: 3060 / 521

Going ahead to step 4:
When dividing 3060 by 521, we get 5 with a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2605 from 3060 and we're left with 455.
Take the next digit (9) from the dividend and append it to 455, then repeat: 4559 / 521

Advancing to step 5:
521 goes into 4559 8 times with a remainder of 391.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 4168 from 4559 and we're left with 391.
Append the next digit (4) from the dividend to 391 and continue with: 3914 / 521

Moving on to step 6:
521 goes into 3914 7 times with a remainder of 267.
The next digit of our result is 7. 
Result so far: 587.0
If we subtract 3647 from 3914, we get 267.
Bring next digit (1) of the dividend behind the 267 and repeat the process: 2671 / 521

On to step 7:
521 can be fit into 2671 5 times, resulting in a remainder of 66.
Use 5 as the next digit of our solution. 
Result so far: 5875.0
Subtracting 2605 from 2671 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
The number 521 fits into 660 1 times, leaving a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 5875.1
If we take 521 away from 660, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 9:
521 can be fit into 1390 2 times, resulting in a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 5875.12
If we subtract 1042 from 1390, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 10:
If we divide 3480 by 521, we get 6 and a remainder of 354.
Put 6 as the next digit of the answer. 
Result so far: 5875.126
Subtract 3126 from 3480 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 11:
521 can be fit into 3540 6 times, resulting in a remainder of 414.
The next digit of our result is 6. 
Result so far: 5875.1266
Deduct 3126 from 3540 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final result is 5875.1266 with a remainder of 0.00414.
