We look at the division of 18507463 by 413 
The aim is to understand the frequency of 413 in 18507463.

Going ahead to step 1:
When dividing 1 by 413, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 413

Moving on to step 2:
413 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 413

Moving on to step 3:
413 can be fit into 185 0 times, resulting in a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 185, we end up with 185.
Include the next digit (0) from the dividend after 185, then repeat: 1850 / 413

Advancing to step 4:
The number 413 fits into 1850 4 times, leaving a remainder of 198.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1652 from 1850, we get 198.
Include the next digit (7) from the dividend after 198, then repeat: 1987 / 413

Moving on to step 5:
413 can be fit into 1987 4 times, resulting in a remainder of 335.
The next digit of our result is 4. 
Result so far: 44.0
If we take 1652 away from 1987, we end up with 335.
Take the next digit (4) from the dividend and append it to 335, then repeat: 3354 / 413

Step 6:
413 goes into 3354 8 times with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
Deduct 3304 from 3354 and we're left with 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 413

Moving on to step 7:
If we divide 506 by 413, we get 1 and a remainder of 93.
Put 1 as the next digit of the answer. 
Result so far: 4481.0
Deduct 413 from 506 and we're left with 93.
Take the next digit (3) from the dividend and append it to 93, then repeat: 933 / 413

Moving on to step 8:
933 divided by 413 is 2 with a remainder of 107.
Use 2 as the next digit of our solution. 
Result so far: 44812.0
Deduct 826 from 933 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 9:
The number 413 fits into 1070 2 times, leaving a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 44812.2
Subtract 826 from 1070 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 10:
413 can be fit into 2440 5 times, resulting in a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 44812.25
If we subtract 2065 from 2440, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 11:
If we divide 3750 by 413, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 44812.259
Subtracting 3717 from 3750 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
When dividing 330 by 413, we get 0 with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 44812.259
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 13:
If we divide 3300 by 413, we get 7 and a remainder of 409.
The next digit of our result is 7. 
Result so far: 44812.25907
Deduct 2891 from 3300 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 14:
The number 413 fits into 4090 9 times, leaving a remainder of 373.
The next digit of our result is 9. 
Result so far: 44812.259079
If we take 3717 away from 4090, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 15:
3730 divided by 413 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 44812.2590799
Deduct 3717 from 3730 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 44812.2590799 with a remaining 1.3e-07.
