We look at the division of 542156 by 79 
We're looking to find how many times 79 goes into 542156.

Going ahead to step 1:
79 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 79

Moving on to step 2:
If we divide 54 by 79, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 79

Moving on to step 3:
When dividing 542 by 79, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 474 from 542 leaves us with 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 79

Moving on to step 4:
The number 79 fits into 681 8 times, leaving a remainder of 49.
The next digit of our result is 8. 
Result so far: 68.0
Subtracting 632 from 681 leaves us with 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 79

Advancing to step 5:
79 goes into 495 6 times with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 686.0
Subtract 474 from 495 to get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 79

On to step 6:
When dividing 216 by 79, we get 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 6862.0
Subtract 158 from 216 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
The number 79 fits into 580 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 6862.7
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.

Step 8:
79 can be fit into 270 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 6862.73
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
The number 79 fits into 330 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 6862.734
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.

Moving on to step 10:
79 goes into 140 1 times with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 6862.7341
Subtract 79 from 140 to get 61.
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 11:
79 can be fit into 610 7 times, resulting in a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 6862.73417
If we take 553 away from 610, we end up 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.

Moving on to step 12:
If we divide 570 by 79, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6862.734177
Subtracting 553 from 570 leaves us with 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 6862.734177, with a leftover of 1.7e-06.
