We look at the division of 354309 by 72 
Let's see how many times 72 fits into 354309.

Moving on to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 72

On to step 2:
35 divided by 72 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 72

Step 3:
72 can be fit into 354 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 66 after subtracting 288 from 354.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 72

Let's proceed to step 4:
When dividing 663 by 72, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 648 from 663, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 72

Moving on to step 5:
150 divided by 72 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 492.0
Deduct 144 from 150 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 72

Step 6:
72 can be fit into 69 0 times, resulting in a remainder of 69.
The next digit of our result is 0. 
Result so far: 4920.0
Deduct 0 from 69 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
72 goes into 690 9 times with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 4920.9
Deduct 648 from 690 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
72 goes into 420 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 4920.95
Subtract 360 from 420 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
600 divided by 72 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 4920.958
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 72, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 4920.9583
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 4920.95833
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 4920.95833 with a remaining 2.4e-05.
