Let's divide 816839 by 79
Our goal is to divide 816839 by 79.

Moving on to step 1:
If we divide 8 by 79, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 79

Moving on to step 2:
81 divided by 79 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 79 from 81 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 79

Moving on to step 3:
26 divided by 79 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 26 and we're left with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 79

On to step 4:
When dividing 268 by 79, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 103.0
The remainder is 31 after subtracting 237 from 268.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 79

Moving on to step 5:
When dividing 313 by 79, we get 3 with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 1033.0
If we subtract 237 from 313, we get 76.
Grab the next digit (9) from the dividend, add it to 76, then carry on: 769 / 79

Moving on to step 6:
769 divided by 79 is 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 10339.0
Deduct 711 from 769 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.

Advancing to step 7:
The number 79 fits into 580 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 10339.7
If we subtract 553 from 580, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
When dividing 270 by 79, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 10339.73
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.

On to step 9:
The number 79 fits into 330 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 10339.734
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.

On to step 10:
79 can be fit into 140 1 times, resulting in a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 10339.7341
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.

Let's proceed to step 11:
79 goes into 610 7 times with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 10339.73417
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 12:
79 goes into 570 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 10339.734177
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.

After the division, we end up with 10339.734177 and a remainder of 1.7e-06.
