Let's divide 429970 by 72
We're looking to find how many times 72 goes into 429970.

Advancing to step 1:
72 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 72

On to step 2:
The number 72 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 72

Step 3:
The number 72 fits into 429 5 times, leaving a remainder of 69.
The next digit of our result is 5. 
Result so far: 5.0
If we take 360 away from 429, we end up with 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 72

Advancing to step 4:
When dividing 699 by 72, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 59.0
The remainder is 51 after subtracting 648 from 699.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 72

Going ahead to step 5:
If we divide 517 by 72, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 597.0
Subtracting 504 from 517 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 72

Step 6:
If we divide 130 by 72, we get 1 and a remainder of 58.
The next digit of our result is 1. 
Result so far: 5971.0
Subtracting 72 from 130 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
If we divide 580 by 72, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 5971.8
If we take 576 away from 580, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
72 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5971.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
72 goes into 400 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 5971.805
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 5971.8055
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 5971.8055, with a leftover of 0.0004.
