We're dividing 394336 by 72 
We're looking to find how many times 72 goes into 394336.

Going ahead to step 1:
If we divide 3 by 72, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 72

Advancing to step 2:
When dividing 39 by 72, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 72

Moving on to step 3:
394 divided by 72 is 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 360 from 394 to get 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 72

On to step 4:
If we divide 343 by 72, we get 4 and a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 288 from 343 to get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 72

Going ahead to step 5:
The number 72 fits into 553 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 547.0
Subtracting 504 from 553 leaves us with 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 72

Step 6:
496 divided by 72 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5476.0
Subtracting 432 from 496 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 7:
When dividing 640 by 72, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 5476.8
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
The number 72 fits into 640 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 5476.88
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 5476.88 with a remaining 0.064.
