11253393 ÷ 288 
We want to figure out the number of times 11253393 can be divided by 288.

Let's proceed to step 1:
288 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 288

On to step 2:
288 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 288

Step 3:
288 goes into 112 0 times with a remainder of 112.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 112 to get 112.
Fetch the next digit (5) from the dividend, attach it to 112 and continue: 1125 / 288

Let's proceed to step 4:
1125 divided by 288 is 3 with a remainder of 261.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 864 from 1125 leaves us with 261.
Take the next digit (3) from the dividend and append it to 261, then repeat: 2613 / 288

Advancing to step 5:
288 goes into 2613 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 2592 from 2613 to get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 288

Going ahead to step 6:
288 goes into 213 0 times with a remainder of 213.
The next digit of our result is 0. 
Result so far: 390.0
The remainder is 213 after subtracting 0 from 213.
Fetch the next digit (9) from the dividend, attach it to 213 and continue: 2139 / 288

Let's proceed to step 7:
The number 288 fits into 2139 7 times, leaving a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 3907.0
Subtracting 2016 from 2139 leaves us with 123.
Append the next digit (3) from the dividend to 123 and continue with: 1233 / 288

Advancing to step 8:
288 can be fit into 1233 4 times, resulting in a remainder of 81.
The next digit of our result is 4. 
Result so far: 39074.0
The remainder is 81 after subtracting 1152 from 1233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
810 divided by 288 is 2 with a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 39074.2
If we subtract 576 from 810, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 10:
If we divide 2340 by 288, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 39074.28
The remainder is 36 after subtracting 2304 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
If we divide 360 by 288, we get 1 and a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 39074.281
Subtracting 288 from 360 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.

Let's proceed to step 12:
288 goes into 720 2 times with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 39074.2812
Subtract 576 from 720 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
If we divide 1440 by 288, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 39074.28125
The remainder is 0 after subtracting 1440 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
0 divided by 288 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39074.28125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
0 divided by 288 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39074.28125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 39074.28125, with a leftover of 0.0.
