Let's divide 515790 by 79
Let's see how many times 79 fits into 515790.

Step 1:
If we divide 5 by 79, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 79

On to step 2:
79 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 79

Moving on to step 3:
The number 79 fits into 515 6 times, leaving a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 474 from 515 leaves us with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 79

Advancing to step 4:
The number 79 fits into 417 5 times, leaving a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 395 from 417 to get 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 79

Moving on to step 5:
79 can be fit into 229 2 times, resulting in a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 652.0
Subtracting 158 from 229 leaves us with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 79

Moving on to step 6:
710 divided by 79 is 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 6528.0
If we subtract 632 from 710, we 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 can be fit into 780 9 times, resulting in a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 6528.9
Subtract 711 from 780 to get 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.
Put 8 as the next digit of the answer. 
Result so far: 6528.98
If we take 632 away from 690, we end up 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:
When dividing 580 by 79, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 6528.987
Deduct 553 from 580 and we're left 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:
The number 79 fits into 270 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 6528.9873
Subtract 237 from 270 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
79 goes into 330 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 6528.98734
Subtract 316 from 330 to 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.

Going ahead to step 12:
140 divided by 79 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 6528.987341
If we take 79 away from 140, we end up 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.

Let's proceed to step 13:
When dividing 610 by 79, we get 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 6528.9873417
Deduct 553 from 610 and we're left with 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:
570 divided by 79 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6528.98734177
The remainder is 17 after subtracting 553 from 570.
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 6528.98734177, with a leftover of 1.7e-08.
