We're dividing 15840788 by 417 
We want to figure out the number of times 15840788 can be divided by 417.

Let's proceed to step 1:
1 divided by 417 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 417

Advancing to step 2:
15 divided by 417 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 417

Moving on to step 3:
When dividing 158 by 417, we get 0 with a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 158 to get 158.
Take the next digit (4) from the dividend and append it to 158, then repeat: 1584 / 417

On to step 4:
1584 divided by 417 is 3 with a remainder of 333.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1251 from 1584 to get 333.
Include the next digit (0) from the dividend after 333, then repeat: 3330 / 417

Advancing to step 5:
When dividing 3330 by 417, we get 7 with a remainder of 411.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 2919 from 3330 to get 411.
Bring next digit (7) of the dividend behind the 411 and repeat the process: 4117 / 417

Step 6:
When dividing 4117 by 417, we get 9 with a remainder of 364.
The next digit of our result is 9. 
Result so far: 379.0
Subtracting 3753 from 4117 leaves us with 364.
Fetch the next digit (8) from the dividend, attach it to 364 and continue: 3648 / 417

Moving on to step 7:
417 goes into 3648 8 times with a remainder of 312.
The next digit of our result is 8. 
Result so far: 3798.0
Deduct 3336 from 3648 and we're left with 312.
Append the next digit (8) from the dividend to 312 and continue with: 3128 / 417

Moving on to step 8:
3128 divided by 417 is 7 with a remainder of 209.
Use 7 as the next digit of our solution. 
Result so far: 37987.0
Deduct 2919 from 3128 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
The number 417 fits into 2090 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 37987.5
If we subtract 2085 from 2090, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
The number 417 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 37987.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
When dividing 500 by 417, we get 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 37987.501
Deduct 417 from 500 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 12:
417 can be fit into 830 1 times, resulting in a remainder of 413.
Use 1 as the next digit of our solution. 
Result so far: 37987.5011
Subtracting 417 from 830 leaves us with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

In conclusion, the division gives 37987.5011 with a balance of 0.00413.
