We look at the division of 429570 by 50 
Let's see how many times 50 fits into 429570.

Step 1:
50 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 50

Going ahead to step 2:
The number 50 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 50

Moving on to step 3:
When dividing 429 by 50, we get 8 with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 400 from 429 to get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 50

Advancing to step 4:
When dividing 295 by 50, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtract 250 from 295 to get 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 50

Going ahead to step 5:
50 goes into 457 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 859.0
Deduct 450 from 457 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 50

Step 6:
If we divide 70 by 50, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 8591.0
Subtracting 50 from 70 leaves us with 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 7:
50 goes into 200 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 8591.4
Subtract 200 from 200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8591.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8591.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8591.4 and a remainder of 0.0.
