Let's divide 13249748 by 578
The aim is to understand the frequency of 578 in 13249748.

Going ahead to step 1:
When dividing 1 by 578, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 578

Going ahead to step 2:
578 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 578

Step 3:
The number 578 fits into 132 0 times, leaving a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 132, we get 132.
Take the next digit (4) from the dividend and append it to 132, then repeat: 1324 / 578

On to step 4:
578 goes into 1324 2 times with a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1156 from 1324 to get 168.
Grab the next digit (9) from the dividend, add it to 168, then carry on: 1689 / 578

Let's proceed to step 5:
578 can be fit into 1689 2 times, resulting in a remainder of 533.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 1156 away from 1689, we end up with 533.
Fetch the next digit (7) from the dividend, attach it to 533 and continue: 5337 / 578

Step 6:
578 goes into 5337 9 times with a remainder of 135.
Write down 9 as next digit of the result. 
Result so far: 229.0
If we take 5202 away from 5337, we end up with 135.
Include the next digit (4) from the dividend after 135, then repeat: 1354 / 578

Going ahead to step 7:
578 can be fit into 1354 2 times, resulting in a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 2292.0
If we take 1156 away from 1354, we end up with 198.
Append the next digit (8) from the dividend to 198 and continue with: 1988 / 578

On to step 8:
If we divide 1988 by 578, we get 3 and a remainder of 254.
Record the quotient 3 as the next digit in the result. 
Result so far: 22923.0
If we take 1734 away from 1988, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 9:
2540 divided by 578 is 4 with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 22923.4
The remainder is 228 after subtracting 2312 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 10:
The number 578 fits into 2280 3 times, leaving a remainder of 546.
Put 3 as the next digit of the answer. 
Result so far: 22923.43
If we take 1734 away from 2280, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Step 11:
The number 578 fits into 5460 9 times, leaving a remainder of 258.
The next digit of our result is 9. 
Result so far: 22923.439
The remainder is 258 after subtracting 5202 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 12:
If we divide 2580 by 578, we get 4 and a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 22923.4394
Deduct 2312 from 2580 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 13:
578 goes into 2680 4 times with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 22923.43944
Deduct 2312 from 2680 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The quotient of the division is 22923.43944, and the remainder is 0.000368.
