We look at the division of 20178986 by 286 
We're looking to find how many times 286 goes into 20178986.

Let's proceed to step 1:
286 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 286

Let's proceed to step 2:
The number 286 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 286

Moving on to step 3:
286 can be fit into 201 0 times, resulting in a remainder of 201.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 201, we end up with 201.
Bring next digit (7) of the dividend behind the 201 and repeat the process: 2017 / 286

Step 4:
When dividing 2017 by 286, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2002 from 2017 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 286

On to step 5:
If we divide 158 by 286, we get 0 and a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtract 0 from 158 to get 158.
Take the next digit (9) from the dividend and append it to 158, then repeat: 1589 / 286

Let's proceed to step 6:
1589 divided by 286 is 5 with a remainder of 159.
Write down 5 as next digit of the result. 
Result so far: 705.0
The remainder is 159 after subtracting 1430 from 1589.
Include the next digit (8) from the dividend after 159, then repeat: 1598 / 286

Let's proceed to step 7:
1598 divided by 286 is 5 with a remainder of 168.
The next digit of our result is 5. 
Result so far: 7055.0
If we subtract 1430 from 1598, we get 168.
Fetch the next digit (6) from the dividend, attach it to 168 and continue: 1686 / 286

Going ahead to step 8:
1686 divided by 286 is 5 with a remainder of 256.
Put 5 as the next digit of the answer. 
Result so far: 70555.0
If we subtract 1430 from 1686, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 9:
When dividing 2560 by 286, we get 8 with a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 70555.8
Subtracting 2288 from 2560 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 10:
2720 divided by 286 is 9 with a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 70555.89
If we subtract 2574 from 2720, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 11:
When dividing 1460 by 286, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 70555.895
Subtract 1430 from 1460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
The number 286 fits into 300 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 70555.8951
Deduct 286 from 300 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
286 can be fit into 140 0 times, resulting in a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 70555.8951
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
When dividing 1400 by 286, we get 4 with a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 70555.895104
If we take 1144 away from 1400, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 15:
The number 286 fits into 2560 8 times, leaving a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 70555.8951048
Subtracting 2288 from 2560 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 16:
286 goes into 2720 9 times with a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 70555.89510489
Subtract 2574 from 2720 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The quotient of the division is 70555.89510489, and the remainder is 1.46e-07.
