We look at the division of 11243579 by 288 
The aim is to understand the frequency of 288 in 11243579.

Let's proceed to step 1:
The number 288 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 288

Step 2:
11 divided by 288 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 288

Going ahead to step 3:
The number 288 fits into 112 0 times, leaving a remainder of 112.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 112 to get 112.
Bring next digit (4) of the dividend behind the 112 and repeat the process: 1124 / 288

Advancing to step 4:
The number 288 fits into 1124 3 times, leaving a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 864 from 1124 and we're left with 260.
Bring next digit (3) of the dividend behind the 260 and repeat the process: 2603 / 288

Going ahead to step 5:
288 goes into 2603 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 2592 from 2603, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 288

Moving on to step 6:
The number 288 fits into 115 0 times, leaving a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 390.0
Deduct 0 from 115 and we're left with 115.
Bring next digit (7) of the dividend behind the 115 and repeat the process: 1157 / 288

Step 7:
288 goes into 1157 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 3904.0
Subtracting 1152 from 1157 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 288

Going ahead to step 8:
When dividing 59 by 288, we get 0 with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 39040.0
Subtract 0 from 59 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
When dividing 590 by 288, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 39040.2
If we subtract 576 from 590, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
When dividing 140 by 288, we get 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 39040.2
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
If we divide 1400 by 288, we get 4 and a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 39040.204
If we take 1152 away from 1400, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 12:
288 goes into 2480 8 times with a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 39040.2048
Subtract 2304 from 2480 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
1760 divided by 288 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 39040.20486
Deduct 1728 from 1760 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
When dividing 320 by 288, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 39040.204861
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
288 goes into 320 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 39040.2048611
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 39040.2048611 and a remainder of 3.2e-07.
