Going ahead to step 1:
79 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 79

Advancing to step 2:
79 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 79

Step 3:
When dividing 211 by 79, we get 2 with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 158 from 211, we get 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 79

Going ahead to step 4:
When dividing 531 by 79, we get 6 with a remainder of 57.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 474 from 531 to get 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 79

Going ahead to step 5:
79 can be fit into 576 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 267.0
If we take 553 away from 576, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 79

Going ahead to step 6:
235 divided by 79 is 2 with a remainder of 77.
Record the quotient 2 as the next digit in the result. 
Result so far: 2672.0
If we subtract 158 from 235, we get 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 79

Going ahead to step 7:
If we divide 773 by 79, we get 9 and a remainder of 62.
The next digit of our result is 9. 
Result so far: 26729.0
If we subtract 711 from 773, we get 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 79

Advancing to step 8:
624 divided by 79 is 7 with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 267297.0
The remainder is 71 after subtracting 553 from 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
710 divided by 79 is 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 267297.8
If we take 632 away from 710, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
If we divide 780 by 79, we get 9 and a remainder of 69.
The next digit of our result is 9. 
Result so far: 267297.89
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.

Advancing to step 11:
690 divided by 79 is 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 267297.898
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.

Going ahead to step 12:
79 goes into 580 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 267297.8987
The remainder is 27 after subtracting 553 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
When dividing 270 by 79, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 267297.89873
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.

Step 14:
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: 267297.898734
The remainder is 14 after subtracting 316 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 15:
79 goes into 140 1 times with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 267297.8987341
The remainder is 61 after subtracting 79 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 16:
79 goes into 610 7 times with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 267297.89873417
Subtracting 553 from 610 leaves us 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.

After the division, we end up with 267297.89873417 and a remainder of 5.7e-08.
