387810 ÷ 79 
We want to divide 387810 by 79.

Step 1:
The number 79 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 79

Going ahead to step 2:
If we divide 38 by 79, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 79

Let's proceed to step 3:
When dividing 387 by 79, we get 4 with a remainder of 71.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 71 after subtracting 316 from 387.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 79

Step 4:
79 can be fit into 718 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 49.0
If we take 711 away from 718, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 79

Moving on to step 5:
When dividing 71 by 79, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 490.0
If we subtract 0 from 71, we get 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 79

Let's proceed to step 6:
The number 79 fits into 710 8 times, leaving a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 4908.0
Subtract 632 from 710 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
79 goes into 780 9 times with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 4908.9
Deduct 711 from 780 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 8:
79 can be fit into 690 8 times, resulting in a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 4908.98
Deduct 632 from 690 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
79 can be fit into 580 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 4908.987
If we take 553 away from 580, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
If we divide 270 by 79, we get 3 and a remainder of 33.
The next digit of our result is 3. 
Result so far: 4908.9873
Deduct 237 from 270 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
330 divided by 79 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4908.98734
If we subtract 316 from 330, 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 12:
If we divide 140 by 79, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 4908.987341
Deduct 79 from 140 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 13:
If we divide 610 by 79, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 4908.9873417
Subtract 553 from 610 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 14:
When dividing 570 by 79, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 4908.98734177
If we subtract 553 from 570, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 4908.98734177, with a leftover of 1.7e-08.
