We're dividing 38578579 by 790 
Our goal is to divide 38578579 by 790.

Advancing to step 1:
3 divided by 790 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 790

Moving on to step 2:
When dividing 38 by 790, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 790

On to step 3:
When dividing 385 by 790, we get 0 with a remainder of 385.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 385 and we're left with 385.
Include the next digit (7) from the dividend after 385, then repeat: 3857 / 790

On to step 4:
790 goes into 3857 4 times with a remainder of 697.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3160 away from 3857, we end up with 697.
Append the next digit (8) from the dividend to 697 and continue with: 6978 / 790

Let's proceed to step 5:
The number 790 fits into 6978 8 times, leaving a remainder of 658.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 6320 from 6978 and we're left with 658.
Fetch the next digit (5) from the dividend, attach it to 658 and continue: 6585 / 790

On to step 6:
The number 790 fits into 6585 8 times, leaving a remainder of 265.
Put 8 as the next digit of the answer. 
Result so far: 488.0
If we subtract 6320 from 6585, we get 265.
Grab the next digit (7) from the dividend, add it to 265, then carry on: 2657 / 790

Moving on to step 7:
790 goes into 2657 3 times with a remainder of 287.
The number 3 becomes the next digit in our result. 
Result so far: 4883.0
Subtract 2370 from 2657 to get 287.
Fetch the next digit (9) from the dividend, attach it to 287 and continue: 2879 / 790

Advancing to step 8:
If we divide 2879 by 790, we get 3 and a remainder of 509.
Put 3 as the next digit of the answer. 
Result so far: 48833.0
Subtract 2370 from 2879 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 9:
790 goes into 5090 6 times with a remainder of 350.
Put 6 as the next digit of the answer. 
Result so far: 48833.6
Subtract 4740 from 5090 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 10:
3500 divided by 790 is 4 with a remainder of 340.
The number 4 becomes the next digit in our result. 
Result so far: 48833.64
If we subtract 3160 from 3500, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
If we divide 3400 by 790, we get 4 and a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 48833.644
Subtracting 3160 from 3400 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 48833.644 with a remainder of 0.024.
