We're dividing 86978340 by 636 
We're looking to find how many times 636 goes into 86978340.

On to step 1:
636 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 636

On to step 2:
If we divide 86 by 636, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 636

Let's proceed to step 3:
The number 636 fits into 869 1 times, leaving a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 636 away from 869, we end up with 233.
Append the next digit (7) from the dividend to 233 and continue with: 2337 / 636

On to step 4:
636 can be fit into 2337 3 times, resulting in a remainder of 429.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 429 after subtracting 1908 from 2337.
Append the next digit (8) from the dividend to 429 and continue with: 4298 / 636

Going ahead to step 5:
4298 divided by 636 is 6 with a remainder of 482.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we take 3816 away from 4298, we end up with 482.
Grab the next digit (3) from the dividend, add it to 482, then carry on: 4823 / 636

On to step 6:
When dividing 4823 by 636, we get 7 with a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 1367.0
If we take 4452 away from 4823, we end up with 371.
Append the next digit (4) from the dividend to 371 and continue with: 3714 / 636

Advancing to step 7:
636 can be fit into 3714 5 times, resulting in a remainder of 534.
Put 5 as the next digit of the answer. 
Result so far: 13675.0
If we subtract 3180 from 3714, we get 534.
Append the next digit (0) from the dividend to 534 and continue with: 5340 / 636

Let's proceed to step 8:
636 can be fit into 5340 8 times, resulting in a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 136758.0
If we take 5088 away from 5340, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 9:
The number 636 fits into 2520 3 times, leaving a remainder of 612.
The number 3 becomes the next digit in our result. 
Result so far: 136758.3
Subtracting 1908 from 2520 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 10:
If we divide 6120 by 636, we get 9 and a remainder of 396.
The number 9 becomes the next digit in our result. 
Result so far: 136758.39
If we subtract 5724 from 6120, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 11:
When dividing 3960 by 636, we get 6 with a remainder of 144.
The next digit of our result is 6. 
Result so far: 136758.396
The remainder is 144 after subtracting 3816 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 12:
If we divide 1440 by 636, we get 2 and a remainder of 168.
The next digit of our result is 2. 
Result so far: 136758.3962
If we subtract 1272 from 1440, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 13:
The number 636 fits into 1680 2 times, leaving a remainder of 408.
Use 2 as the next digit of our solution. 
Result so far: 136758.39622
The remainder is 408 after subtracting 1272 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The quotient of the division is 136758.39622, and the remainder is 0.000408.
