352686 ÷ 72 
We want to figure out the number of times 352686 can be divided by 72.

On to step 1:
72 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 72

On to step 2:
The number 72 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 72

On to step 3:
If we divide 352 by 72, we get 4 and a remainder of 64.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 288 from 352 and we're left with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 72

Moving on to step 4:
The number 72 fits into 646 8 times, leaving a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 576 away from 646, we end up with 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 72

On to step 5:
708 divided by 72 is 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
If we subtract 648 from 708, we get 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 72

Step 6:
When dividing 606 by 72, we get 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 4898.0
Deduct 576 from 606 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 72, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4898.4
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 72 fits into 120 1 times, leaving a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 4898.41
If we subtract 72 from 120, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 4898.416
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
480 divided by 72 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 4898.4166
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 4898.4166, and the remainder is 0.00048.
