866286 divided by 79 
Let's see how many times 79 fits into 866286.

On to step 1:
79 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 79

Advancing to step 2:
79 goes into 86 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 79 from 86, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 79

Advancing to step 3:
79 goes into 76 0 times with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 76, we end up with 76.
Include the next digit (2) from the dividend after 76, then repeat: 762 / 79

Going ahead to step 4:
The number 79 fits into 762 9 times, leaving a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
The remainder is 51 after subtracting 711 from 762.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 79

Advancing to step 5:
79 can be fit into 518 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1096.0
Subtract 474 from 518 to get 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 79

Advancing to step 6:
When dividing 446 by 79, we get 5 with a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 10965.0
If we take 395 away from 446, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
79 goes into 510 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 10965.6
The remainder is 36 after subtracting 474 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
If we divide 360 by 79, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 10965.64
Subtracting 316 from 360 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
79 can be fit into 440 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 10965.645
The remainder is 45 after subtracting 395 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
When dividing 450 by 79, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 10965.6455
Deduct 395 from 450 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 10965.6455 with a remaining 0.00055.
