We're dividing 71226836 by 286 
Our goal is to divide 71226836 by 286.

Step 1:
286 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 286

Going ahead to step 2:
If we divide 71 by 286, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 286

Going ahead to step 3:
712 divided by 286 is 2 with a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 572 away from 712, we end up with 140.
Include the next digit (2) from the dividend after 140, then repeat: 1402 / 286

Moving on to step 4:
286 goes into 1402 4 times with a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 1144 away from 1402, we end up with 258.
Take the next digit (6) from the dividend and append it to 258, then repeat: 2586 / 286

Moving on to step 5:
The number 286 fits into 2586 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 249.0
Subtract 2574 from 2586 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 286

Going ahead to step 6:
286 goes into 128 0 times with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 2490.0
Subtract 0 from 128 to get 128.
Fetch the next digit (3) from the dividend, attach it to 128 and continue: 1283 / 286

Going ahead to step 7:
If we divide 1283 by 286, we get 4 and a remainder of 139.
Record the quotient 4 as the next digit in the result. 
Result so far: 24904.0
Deduct 1144 from 1283 and we're left with 139.
Grab the next digit (6) from the dividend, add it to 139, then carry on: 1396 / 286

Going ahead to step 8:
If we divide 1396 by 286, we get 4 and a remainder of 252.
Put 4 as the next digit of the answer. 
Result so far: 249044.0
If we subtract 1144 from 1396, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 9:
When dividing 2520 by 286, we get 8 with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 249044.8
If we subtract 2288 from 2520, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 10:
If we divide 2320 by 286, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 249044.88
Deduct 2288 from 2320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 249044.88, and the remainder is 0.032.
