We divide 680435 by 72
We want to figure out the number of times 680435 can be divided by 72.

Advancing to step 1:
6 divided by 72 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 72

On to step 2:
The number 72 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 72

Advancing to step 3:
72 can be fit into 680 9 times, resulting in a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 648 from 680 to get 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 72

Step 4:
If we divide 324 by 72, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
The remainder is 36 after subtracting 288 from 324.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 72

Going ahead to step 5:
72 goes into 363 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 945.0
If we take 360 away from 363, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 72

Let's proceed to step 6:
72 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 9450.0
If we take 0 away from 35, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
If we divide 350 by 72, we get 4 and a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 9450.4
If we subtract 288 from 350, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
If we divide 620 by 72, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 9450.48
If we subtract 576 from 620, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
440 divided by 72 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 9450.486
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 9450.4861
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
72 goes into 80 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 9450.48611
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 9450.48611, and the remainder is 8e-06.
