We look at the division of 52949446 by 376 
The aim is to understand the frequency of 376 in 52949446.

On to step 1:
5 divided by 376 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 376

On to step 2:
376 goes into 52 0 times with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 376

On to step 3:
376 goes into 529 1 times with a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 376 from 529 to get 153.
Bring next digit (4) of the dividend behind the 153 and repeat the process: 1534 / 376

Let's proceed to step 4:
376 can be fit into 1534 4 times, resulting in a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1504 from 1534 and we're left with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 376

Moving on to step 5:
309 divided by 376 is 0 with a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtract 0 from 309 to get 309.
Take the next digit (4) from the dividend and append it to 309, then repeat: 3094 / 376

On to step 6:
The number 376 fits into 3094 8 times, leaving a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 1408.0
The remainder is 86 after subtracting 3008 from 3094.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 376

Let's proceed to step 7:
If we divide 864 by 376, we get 2 and a remainder of 112.
The next digit of our result is 2. 
Result so far: 14082.0
Subtracting 752 from 864 leaves us with 112.
Take the next digit (6) from the dividend and append it to 112, then repeat: 1126 / 376

Moving on to step 8:
1126 divided by 376 is 2 with a remainder of 374.
The number 2 becomes the next digit in our result. 
Result so far: 140822.0
If we subtract 752 from 1126, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 9:
376 can be fit into 3740 9 times, resulting in a remainder of 356.
Write down 9 as next digit of the result. 
Result so far: 140822.9
The remainder is 356 after subtracting 3384 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
The number 376 fits into 3560 9 times, leaving a remainder of 176.
Use 9 as the next digit of our solution. 
Result so far: 140822.99
If we take 3384 away from 3560, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 140822.99, with a leftover of 0.176.
