We look at the division of 525749 by 40 
We want to figure out the number of times 525749 can be divided by 40.

Let's proceed to step 1:
If we divide 5 by 40, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 40

Let's proceed to step 2:
40 goes into 52 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 40 from 52.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 40

Going ahead to step 3:
The number 40 fits into 125 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 5 after subtracting 120 from 125.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 40

Moving on to step 4:
The number 40 fits into 57 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtracting 40 from 57 leaves us with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 40

Going ahead to step 5:
40 goes into 174 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 1314.0
The remainder is 14 after subtracting 160 from 174.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 40

On to step 6:
40 can be fit into 149 3 times, resulting in a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 13143.0
Subtract 120 from 149 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 40 fits into 290 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 13143.7
The remainder is 10 after subtracting 280 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
40 goes into 100 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 13143.72
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 40 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13143.725
If we take 200 away from 200, we end up 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 10:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13143.725
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.

Step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13143.725
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 13143.725, with a leftover of 0.0.
