3115603 ÷ 379 
The aim is to understand the frequency of 379 in 3115603.

Advancing to step 1:
3 divided by 379 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 379

Let's proceed to step 2:
379 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 379

Moving on to step 3:
311 divided by 379 is 0 with a remainder of 311.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 311 to get 311.
Bring next digit (5) of the dividend behind the 311 and repeat the process: 3115 / 379

Going ahead to step 4:
379 can be fit into 3115 8 times, resulting in a remainder of 83.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 3032 from 3115 leaves us with 83.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 379

Going ahead to step 5:
If we divide 836 by 379, we get 2 and a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 82.0
Deduct 758 from 836 and we're left with 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 379

Step 6:
379 can be fit into 780 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 822.0
Subtracting 758 from 780 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 379

Let's proceed to step 7:
379 goes into 223 0 times with a remainder of 223.
Use 0 as the next digit of our solution. 
Result so far: 8220.0
Subtract 0 from 223 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 8:
2230 divided by 379 is 5 with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 8220.5
The remainder is 335 after subtracting 1895 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 9:
379 goes into 3350 8 times with a remainder of 318.
The number 8 becomes the next digit in our result. 
Result so far: 8220.58
Subtracting 3032 from 3350 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 10:
If we divide 3180 by 379, we get 8 and a remainder of 148.
Put 8 as the next digit of the answer. 
Result so far: 8220.588
Subtracting 3032 from 3180 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 8220.588, with a leftover of 0.0148.
