305089 divided by 72 
Let's see how many times 72 fits into 305089.

Step 1:
3 divided by 72 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 72

Let's proceed to step 2:
When dividing 30 by 72, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 72

Advancing to step 3:
If we divide 305 by 72, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 288 away from 305, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 72

On to step 4:
72 can be fit into 170 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 144 from 170 leaves us with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 72

Advancing to step 5:
The number 72 fits into 268 3 times, leaving a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 423.0
If we take 216 away from 268, we end up with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 72

Going ahead to step 6:
72 goes into 529 7 times with a remainder of 25.
The next digit of our result is 7. 
Result so far: 4237.0
Deduct 504 from 529 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
When dividing 250 by 72, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 4237.3
The remainder is 34 after subtracting 216 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 72 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 4237.34
If we take 288 away from 340, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
The number 72 fits into 520 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 4237.347
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 72, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4237.3472
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 72, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 4237.34722
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 4237.34722, and the remainder is 1.6e-05.
