We look at the division of 336989 by 72 
Let's see how many times 72 fits into 336989.

Moving on to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 72

On to step 2:
The number 72 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 72

Moving on to step 3:
336 divided by 72 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 48 after subtracting 288 from 336.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 72

Going ahead to step 4:
72 goes into 489 6 times with a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 432 away from 489, we end up with 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 72

Going ahead to step 5:
72 can be fit into 578 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 468.0
Subtracting 576 from 578 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 72

Going ahead to step 6:
When dividing 29 by 72, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 4680.0
The remainder is 29 after subtracting 0 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
72 can be fit into 290 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4680.4
Subtract 288 from 290 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
72 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4680.4
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 72 fits into 200 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 4680.402
Subtracting 144 from 200 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.

On to step 10:
72 goes into 560 7 times with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 4680.4027
If we take 504 away from 560, we end up 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.

Going ahead to step 11:
The number 72 fits into 560 7 times, leaving a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 4680.40277
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.

After the division, we end up with 4680.40277 and a remainder of 5.6e-05.
