We're dividing 55179382 by 381 
The aim is to understand the frequency of 381 in 55179382.

Let's proceed to step 1:
381 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 381

Going ahead to step 2:
When dividing 55 by 381, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 381

Step 3:
381 goes into 551 1 times with a remainder of 170.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 381 from 551 leaves us with 170.
Include the next digit (7) from the dividend after 170, then repeat: 1707 / 381

Going ahead to step 4:
The number 381 fits into 1707 4 times, leaving a remainder of 183.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 1524 from 1707 and we're left with 183.
Fetch the next digit (9) from the dividend, attach it to 183 and continue: 1839 / 381

Moving on to step 5:
381 goes into 1839 4 times with a remainder of 315.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we subtract 1524 from 1839, we get 315.
Include the next digit (3) from the dividend after 315, then repeat: 3153 / 381

Advancing to step 6:
The number 381 fits into 3153 8 times, leaving a remainder of 105.
Use 8 as the next digit of our solution. 
Result so far: 1448.0
The remainder is 105 after subtracting 3048 from 3153.
Include the next digit (8) from the dividend after 105, then repeat: 1058 / 381

On to step 7:
381 goes into 1058 2 times with a remainder of 296.
The next digit of our result is 2. 
Result so far: 14482.0
If we subtract 762 from 1058, we get 296.
Bring next digit (2) of the dividend behind the 296 and repeat the process: 2962 / 381

Going ahead to step 8:
If we divide 2962 by 381, we get 7 and a remainder of 295.
Write down 7 as next digit of the result. 
Result so far: 144827.0
Deduct 2667 from 2962 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 9:
The number 381 fits into 2950 7 times, leaving a remainder of 283.
Write down 7 as next digit of the result. 
Result so far: 144827.7
Subtracting 2667 from 2950 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.

Going ahead to step 10:
2830 divided by 381 is 7 with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 144827.77
Subtract 2667 from 2830 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

After the division, we end up with 144827.77 and a remainder of 0.163.
