We look at the division of 340437 by 72 
We want to figure out the number of times 340437 can be divided by 72.

On to step 1:
72 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 72

Going ahead to step 2:
34 divided by 72 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 72

Going ahead to step 3:
If we divide 340 by 72, we get 4 and a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 52 after subtracting 288 from 340.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 72

Step 4:
If we divide 524 by 72, we get 7 and a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 504 from 524, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 72

Let's proceed to step 5:
72 can be fit into 203 2 times, resulting in a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 472.0
If we take 144 away from 203, we end up with 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 72

Advancing to step 6:
597 divided by 72 is 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 4728.0
The remainder is 21 after subtracting 576 from 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 72, we get 2 with a remainder of 66.
The next digit of our result is 2. 
Result so far: 4728.2
Subtracting 144 from 210 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
72 goes into 660 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 4728.29
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
72 can be fit into 120 1 times, resulting in a remainder of 48.
The next digit of our result is 1. 
Result so far: 4728.291
Subtracting 72 from 120 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
72 goes into 480 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 4728.2916
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
72 goes into 480 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 4728.29166
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 4728.29166, with a leftover of 4.8e-05.
