54553456 ÷ 413 
The aim is to understand the frequency of 413 in 54553456.

Advancing to step 1:
413 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 413

Step 2:
413 goes into 54 0 times with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 413

On to step 3:
The number 413 fits into 545 1 times, leaving a remainder of 132.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 413 from 545 leaves us with 132.
Take the next digit (5) from the dividend and append it to 132, then repeat: 1325 / 413

Advancing to step 4:
413 goes into 1325 3 times with a remainder of 86.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1239 from 1325 to get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 413

Let's proceed to step 5:
The number 413 fits into 863 2 times, leaving a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 132.0
The remainder is 37 after subtracting 826 from 863.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 413

On to step 6:
413 can be fit into 374 0 times, resulting in a remainder of 374.
The next digit of our result is 0. 
Result so far: 1320.0
Subtract 0 from 374 to get 374.
Fetch the next digit (5) from the dividend, attach it to 374 and continue: 3745 / 413

Step 7:
413 can be fit into 3745 9 times, resulting in a remainder of 28.
The next digit of our result is 9. 
Result so far: 13209.0
Subtract 3717 from 3745 to get 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 413

Moving on to step 8:
413 can be fit into 286 0 times, resulting in a remainder of 286.
The next digit of our result is 0. 
Result so far: 132090.0
Subtract 0 from 286 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 9:
When dividing 2860 by 413, we get 6 with a remainder of 382.
Put 6 as the next digit of the answer. 
Result so far: 132090.6
If we subtract 2478 from 2860, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 10:
The number 413 fits into 3820 9 times, leaving a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 132090.69
Subtracting 3717 from 3820 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 11:
1030 divided by 413 is 2 with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 132090.692
The remainder is 204 after subtracting 826 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 12:
If we divide 2040 by 413, we get 4 and a remainder of 388.
The next digit of our result is 4. 
Result so far: 132090.6924
Deduct 1652 from 2040 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 13:
3880 divided by 413 is 9 with a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 132090.69249
The remainder is 163 after subtracting 3717 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 14:
1630 divided by 413 is 3 with a remainder of 391.
Write down 3 as next digit of the result. 
Result so far: 132090.692493
Subtract 1239 from 1630 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 15:
If we divide 3910 by 413, we get 9 and a remainder of 193.
Record the quotient 9 as the next digit in the result. 
Result so far: 132090.6924939
The remainder is 193 after subtracting 3717 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 16:
1930 divided by 413 is 4 with a remainder of 278.
Write down 4 as next digit of the result. 
Result so far: 132090.69249394
The remainder is 278 after subtracting 1652 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final outcome is 132090.69249394, with a leftover of 2.78e-07.
