55265459 divided by 394 
The aim is to understand the frequency of 394 in 55265459.

On to step 1:
If we divide 5 by 394, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 394

Step 2:
The number 394 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 394

Going ahead to step 3:
394 goes into 552 1 times with a remainder of 158.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 394 from 552 leaves us with 158.
Take the next digit (6) from the dividend and append it to 158, then repeat: 1586 / 394

Let's proceed to step 4:
When dividing 1586 by 394, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 10 after subtracting 1576 from 1586.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 394

Advancing to step 5:
394 can be fit into 105 0 times, resulting in a remainder of 105.
The next digit of our result is 0. 
Result so far: 140.0
If we subtract 0 from 105, we get 105.
Bring next digit (4) of the dividend behind the 105 and repeat the process: 1054 / 394

Advancing to step 6:
394 goes into 1054 2 times with a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 1402.0
If we subtract 788 from 1054, we get 266.
Include the next digit (5) from the dividend after 266, then repeat: 2665 / 394

Going ahead to step 7:
2665 divided by 394 is 6 with a remainder of 301.
Write down 6 as next digit of the result. 
Result so far: 14026.0
Subtract 2364 from 2665 to get 301.
Grab the next digit (9) from the dividend, add it to 301, then carry on: 3019 / 394

Moving on to step 8:
The number 394 fits into 3019 7 times, leaving a remainder of 261.
The number 7 becomes the next digit in our result. 
Result so far: 140267.0
Deduct 2758 from 3019 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 9:
394 can be fit into 2610 6 times, resulting in a remainder of 246.
Write down 6 as next digit of the result. 
Result so far: 140267.6
The remainder is 246 after subtracting 2364 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
2460 divided by 394 is 6 with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 140267.66
Deduct 2364 from 2460 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 140267.66 with a remainder of 0.096.
