We're dividing 19686131 by 286 
We want to divide 19686131 by 286.

Step 1:
The number 286 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 286

Moving on to step 2:
If we divide 19 by 286, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 286

On to step 3:
The number 286 fits into 196 0 times, leaving a remainder of 196.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 196, we get 196.
Append the next digit (8) from the dividend to 196 and continue with: 1968 / 286

Moving on to step 4:
When dividing 1968 by 286, we get 6 with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 1716 from 1968 and we're left with 252.
Include the next digit (6) from the dividend after 252, then repeat: 2526 / 286

Moving on to step 5:
286 can be fit into 2526 8 times, resulting in a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtract 2288 from 2526 to get 238.
Append the next digit (1) from the dividend to 238 and continue with: 2381 / 286

Step 6:
The number 286 fits into 2381 8 times, leaving a remainder of 93.
Use 8 as the next digit of our solution. 
Result so far: 688.0
If we take 2288 away from 2381, we end up with 93.
Fetch the next digit (3) from the dividend, attach it to 93 and continue: 933 / 286

On to step 7:
When dividing 933 by 286, we get 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 6883.0
Deduct 858 from 933 and we're left with 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 286

Advancing to step 8:
286 can be fit into 751 2 times, resulting in a remainder of 179.
Write down 2 as next digit of the result. 
Result so far: 68832.0
The remainder is 179 after subtracting 572 from 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 9:
1790 divided by 286 is 6 with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 68832.6
Subtract 1716 from 1790 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 286, we get 2 and a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 68832.62
If we take 572 away from 740, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 11:
If we divide 1680 by 286, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 68832.625
If we subtract 1430 from 1680, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
The number 286 fits into 2500 8 times, leaving a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 68832.6258
Deduct 2288 from 2500 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
The number 286 fits into 2120 7 times, leaving a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 68832.62587
If we subtract 2002 from 2120, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 14:
If we divide 1180 by 286, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 68832.625874
Deduct 1144 from 1180 and we're left with 36.
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 15:
360 divided by 286 is 1 with a remainder of 74.
The next digit of our result is 1. 
Result so far: 68832.6258741
Deduct 286 from 360 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 16:
286 goes into 740 2 times with a remainder of 168.
The next digit of our result is 2. 
Result so far: 68832.62587412
Subtract 572 from 740 to 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.

After the division, we end up with 68832.62587412 and a remainder of 1.68e-07.
