57293729 ÷ 15 
Let's see how many times 15 fits into 57293729.

Going ahead to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 15

Advancing to step 2:
If we divide 57 by 15, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 45 from 57, we get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 15

Advancing to step 3:
15 goes into 122 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 120 from 122 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 15

Moving on to step 4:
If we divide 29 by 15, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 381.0
The remainder is 14 after subtracting 15 from 29.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 15

Let's proceed to step 5:
The number 15 fits into 143 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 3819.0
The remainder is 8 after subtracting 135 from 143.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 15

Moving on to step 6:
87 divided by 15 is 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 38195.0
Subtract 75 from 87 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 15

Moving on to step 7:
15 goes into 122 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 381958.0
Subtracting 120 from 122 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 15

Let's proceed to step 8:
If we divide 29 by 15, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 3819581.0
If we subtract 15 from 29, 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.

Step 9:
15 can be fit into 140 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 3819581.9
Subtracting 135 from 140 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3819581.93
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3819581.933
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 3819581.933 with a balance of 0.0005.
