We look at the division of 77836503 by 413 
The aim is to understand the frequency of 413 in 77836503.

Going ahead to step 1:
413 goes into 7 0 times 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.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 413

Advancing to step 2:
When dividing 77 by 413, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 413

Advancing to step 3:
If we divide 778 by 413, we get 1 and a remainder of 365.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 413 from 778 to get 365.
Take the next digit (3) from the dividend and append it to 365, then repeat: 3653 / 413

On to step 4:
When dividing 3653 by 413, we get 8 with a remainder of 349.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3304 from 3653 to get 349.
Bring next digit (6) of the dividend behind the 349 and repeat the process: 3496 / 413

On to step 5:
The number 413 fits into 3496 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtract 3304 from 3496 to get 192.
Grab the next digit (5) from the dividend, add it to 192, then carry on: 1925 / 413

Advancing to step 6:
413 can be fit into 1925 4 times, resulting in a remainder of 273.
The number 4 becomes the next digit in our result. 
Result so far: 1884.0
If we take 1652 away from 1925, we end up with 273.
Bring next digit (0) of the dividend behind the 273 and repeat the process: 2730 / 413

On to step 7:
413 can be fit into 2730 6 times, resulting in a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 18846.0
Subtract 2478 from 2730 to get 252.
Include the next digit (3) from the dividend after 252, then repeat: 2523 / 413

Let's proceed to step 8:
413 goes into 2523 6 times with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 188466.0
The remainder is 45 after subtracting 2478 from 2523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
The number 413 fits into 450 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 188466.1
Subtracting 413 from 450 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
370 divided by 413 is 0 with a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 188466.1
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 11:
The number 413 fits into 3700 8 times, leaving a remainder of 396.
Put 8 as the next digit of the answer. 
Result so far: 188466.108
Subtract 3304 from 3700 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 12:
413 goes into 3960 9 times with a remainder of 243.
The number 9 becomes the next digit in our result. 
Result so far: 188466.1089
If we take 3717 away from 3960, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 13:
The number 413 fits into 2430 5 times, leaving a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 188466.10895
Deduct 2065 from 2430 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 14:
3650 divided by 413 is 8 with a remainder of 346.
The number 8 becomes the next digit in our result. 
Result so far: 188466.108958
The remainder is 346 after subtracting 3304 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 15:
3460 divided by 413 is 8 with a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 188466.1089588
Deduct 3304 from 3460 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final result is 188466.1089588 with a remainder of 1.56e-06.
