We look at the division of 34252128 by 379 
The aim is to understand the frequency of 379 in 34252128.

Advancing to step 1:
3 divided by 379 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 379

On to step 2:
If we divide 34 by 379, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 379

Let's proceed to step 3:
If we divide 342 by 379, we get 0 and a remainder of 342.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 342, we end up with 342.
Include the next digit (5) from the dividend after 342, then repeat: 3425 / 379

Step 4:
The number 379 fits into 3425 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 3411 from 3425 to get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 379

Step 5:
142 divided by 379 is 0 with a remainder of 142.
Write down 0 as next digit of the result. 
Result so far: 90.0
The remainder is 142 after subtracting 0 from 142.
Bring next digit (1) of the dividend behind the 142 and repeat the process: 1421 / 379

Let's proceed to step 6:
If we divide 1421 by 379, we get 3 and a remainder of 284.
The number 3 becomes the next digit in our result. 
Result so far: 903.0
The remainder is 284 after subtracting 1137 from 1421.
Grab the next digit (2) from the dividend, add it to 284, then carry on: 2842 / 379

Step 7:
If we divide 2842 by 379, we get 7 and a remainder of 189.
Use 7 as the next digit of our solution. 
Result so far: 9037.0
Deduct 2653 from 2842 and we're left with 189.
Bring next digit (8) of the dividend behind the 189 and repeat the process: 1898 / 379

On to step 8:
1898 divided by 379 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 90375.0
If we subtract 1895 from 1898, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
The number 379 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 90375.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 379 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 90375.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 90375.0 and a remainder of 0.3.
