7700425 ÷ 413 
The aim is to understand the frequency of 413 in 7700425.

Let's proceed to step 1:
When dividing 7 by 413, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 413

Step 2:
413 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 413

Moving on to step 3:
413 can be fit into 770 1 times, resulting in a remainder of 357.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 413 from 770 to get 357.
Grab the next digit (0) from the dividend, add it to 357, then carry on: 3570 / 413

Let's proceed to step 4:
When dividing 3570 by 413, we get 8 with a remainder of 266.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 266 after subtracting 3304 from 3570.
Take the next digit (4) from the dividend and append it to 266, then repeat: 2664 / 413

Advancing to step 5:
2664 divided by 413 is 6 with a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 186.0
Deduct 2478 from 2664 and we're left with 186.
Append the next digit (2) from the dividend to 186 and continue with: 1862 / 413

Step 6:
1862 divided by 413 is 4 with a remainder of 210.
The next digit of our result is 4. 
Result so far: 1864.0
Subtract 1652 from 1862 to get 210.
Bring next digit (5) of the dividend behind the 210 and repeat the process: 2105 / 413

Let's proceed to step 7:
If we divide 2105 by 413, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 18645.0
Subtract 2065 from 2105 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 413 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 18645.0
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 9:
413 can be fit into 4000 9 times, resulting in a remainder of 283.
The next digit of our result is 9. 
Result so far: 18645.09
Subtracting 3717 from 4000 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 10:
If we divide 2830 by 413, we get 6 and a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 18645.096
Subtract 2478 from 2830 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 11:
413 goes into 3520 8 times with a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 18645.0968
Subtracting 3304 from 3520 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 12:
The number 413 fits into 2160 5 times, leaving a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 18645.09685
Subtracting 2065 from 2160 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
950 divided by 413 is 2 with a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 18645.096852
The remainder is 124 after subtracting 826 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 14:
If we divide 1240 by 413, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 18645.0968523
Subtract 1239 from 1240 to 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 15:
413 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 18645.0968523
Subtracting 0 from 10 leaves us 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.

The final result is 18645.0968523 with a remainder of 1e-08.
