We're dividing 88220643 by 286 
Let's see how many times 286 fits into 88220643.

Step 1:
The number 286 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 286

Going ahead to step 2:
286 goes into 88 0 times with a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Append the next digit (2) from the dividend to 88 and continue with: 882 / 286

Step 3:
882 divided by 286 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 858 away from 882, we end up with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 286

Let's proceed to step 4:
If we divide 242 by 286, we get 0 and a remainder of 242.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 242 leaves us with 242.
Bring next digit (0) of the dividend behind the 242 and repeat the process: 2420 / 286

Moving on to step 5:
286 can be fit into 2420 8 times, resulting in a remainder of 132.
The next digit of our result is 8. 
Result so far: 308.0
Deduct 2288 from 2420 and we're left with 132.
Grab the next digit (6) from the dividend, add it to 132, then carry on: 1326 / 286

On to step 6:
If we divide 1326 by 286, we get 4 and a remainder of 182.
The number 4 becomes the next digit in our result. 
Result so far: 3084.0
Deduct 1144 from 1326 and we're left with 182.
Append the next digit (4) from the dividend to 182 and continue with: 1824 / 286

Moving on to step 7:
1824 divided by 286 is 6 with a remainder of 108.
The next digit of our result is 6. 
Result so far: 30846.0
Subtract 1716 from 1824 to get 108.
Take the next digit (3) from the dividend and append it to 108, then repeat: 1083 / 286

On to step 8:
When dividing 1083 by 286, we get 3 with a remainder of 225.
Put 3 as the next digit of the answer. 
Result so far: 308463.0
If we take 858 away from 1083, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
When dividing 2250 by 286, we get 7 with a remainder of 248.
Write down 7 as next digit of the result. 
Result so far: 308463.7
If we take 2002 away from 2250, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
If we divide 2480 by 286, we get 8 and a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 308463.78
Subtract 2288 from 2480 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 11:
1920 divided by 286 is 6 with a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 308463.786
If we take 1716 away from 1920, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 12:
When dividing 2040 by 286, we get 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 308463.7867
If we take 2002 away from 2040, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
If we divide 380 by 286, we get 1 and a remainder of 94.
Write down 1 as next digit of the result. 
Result so far: 308463.78671
Subtract 286 from 380 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 14:
940 divided by 286 is 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 308463.786713
Subtracting 858 from 940 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 15:
820 divided by 286 is 2 with a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 308463.7867132
Subtracting 572 from 820 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 16:
When dividing 2480 by 286, we get 8 with a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 308463.78671328
Subtract 2288 from 2480 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 308463.78671328 with a remainder of 1.92e-07.
