We're dividing 15408572 by 368 
The aim is to understand the frequency of 368 in 15408572.

Step 1:
1 divided by 368 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 368

On to step 2:
368 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 368

Advancing to step 3:
368 goes into 154 0 times with a remainder of 154.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Fetch the next digit (0) from the dividend, attach it to 154 and continue: 1540 / 368

Moving on to step 4:
1540 divided by 368 is 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 1472 from 1540 leaves us with 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 368

Moving on to step 5:
368 can be fit into 688 1 times, resulting in a remainder of 320.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 368 from 688 to get 320.
Grab the next digit (5) from the dividend, add it to 320, then carry on: 3205 / 368

Advancing to step 6:
If we divide 3205 by 368, we get 8 and a remainder of 261.
Put 8 as the next digit of the answer. 
Result so far: 418.0
If we subtract 2944 from 3205, we get 261.
Grab the next digit (7) from the dividend, add it to 261, then carry on: 2617 / 368

On to step 7:
368 goes into 2617 7 times with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 4187.0
If we take 2576 away from 2617, we end up with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 368

Moving on to step 8:
If we divide 412 by 368, we get 1 and a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 41871.0
The remainder is 44 after subtracting 368 from 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
368 goes into 440 1 times with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 41871.1
Subtracting 368 from 440 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
The number 368 fits into 720 1 times, leaving a remainder of 352.
The number 1 becomes the next digit in our result. 
Result so far: 41871.11
Subtract 368 from 720 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Our division results in 41871.11 with a remaining 0.352.
