We're dividing 864436 by 86 
Let's see how many times 86 fits into 864436.

Moving on to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 86

On to step 2:
86 divided by 86 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 86 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 86

Going ahead to step 3:
When dividing 4 by 86, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 86

Moving on to step 4:
The number 86 fits into 44 0 times, leaving a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 86

Advancing to step 5:
86 goes into 443 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 1005.0
The remainder is 13 after subtracting 430 from 443.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 86

Moving on to step 6:
When dividing 136 by 86, we get 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 10051.0
The remainder is 50 after subtracting 86 from 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
86 can be fit into 500 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 10051.5
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
700 divided by 86 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 10051.58
If we take 688 away from 700, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 86, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 10051.581
Subtracting 86 from 120 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
86 goes into 340 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 10051.5813
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
When dividing 820 by 86, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 10051.58139
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
86 goes into 460 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 10051.581395
Subtracting 430 from 460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 10051.5813953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 10051.58139534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 10051.58139534, and the remainder is 7.6e-08.
