286355 ÷ 72 
We want to figure out the number of times 286355 can be divided by 72.

Moving on to step 1:
If we divide 2 by 72, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 72

Advancing to step 2:
If we divide 28 by 72, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 72

Moving on to step 3:
72 goes into 286 3 times with a remainder of 70.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 216 from 286 leaves us with 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 72

Going ahead to step 4:
When dividing 703 by 72, we get 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 648 from 703 and we're left with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 72

Going ahead to step 5:
72 can be fit into 555 7 times, resulting in a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 397.0
Subtract 504 from 555 to get 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 72

Let's proceed to step 6:
The number 72 fits into 515 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 3977.0
If we take 504 away from 515, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 72 fits into 110 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 3977.1
If we subtract 72 from 110, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
When dividing 380 by 72, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 3977.15
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 72 fits into 200 2 times, leaving a remainder of 56.
The next digit of our result is 2. 
Result so far: 3977.152
The remainder is 56 after subtracting 144 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
When dividing 560 by 72, we get 7 with a remainder of 56.
The next digit of our result is 7. 
Result so far: 3977.1527
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
The number 72 fits into 560 7 times, leaving a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 3977.15277
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 3977.15277 and a remainder of 5.6e-05.
