Let's divide 66839 by 79
We want to divide 66839 by 79.

On to step 1:
79 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 79

Let's proceed to step 2:
When dividing 66 by 79, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 79

Going ahead to step 3:
When dividing 668 by 79, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 632 from 668, we get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 79

Going ahead to step 4:
79 can be fit into 363 4 times, resulting in a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtract 316 from 363 to get 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 79

Going ahead to step 5:
When dividing 479 by 79, we get 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 846.0
The remainder is 5 after subtracting 474 from 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 6:
50 divided by 79 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 846.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
When dividing 500 by 79, we get 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 846.06
If we take 474 away from 500, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
260 divided by 79 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 846.063
Subtracting 237 from 260 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
79 goes into 230 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 846.0632
The remainder is 72 after subtracting 158 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
The number 79 fits into 720 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 846.06329
If we take 711 away from 720, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
When dividing 90 by 79, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 846.063291
Subtract 79 from 90 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
79 can be fit into 110 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 846.0632911
Subtract 79 from 110 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 846.0632911 with a remainder of 3.1e-07.
