We're dividing 429429 by 10 
Our goal is to divide 429429 by 10.

Moving on to step 1:
10 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 10

Going ahead to step 2:
42 divided by 10 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 40 from 42 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 10

On to step 3:
The number 10 fits into 29 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 20 away from 29, we end up with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 10

Going ahead to step 4:
The number 10 fits into 94 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 429.0
If we subtract 90 from 94, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 10

Moving on to step 5:
The number 10 fits into 42 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4294.0
If we take 40 away from 42, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 10

Step 6:
29 divided by 10 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 42942.0
Deduct 20 from 29 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 10, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 42942.9
The remainder is 0 after subtracting 90 from 90.
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 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42942.9
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.

Let's proceed to step 9:
0 divided by 10 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42942.9
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.

Our division results in 42942.9 with a remaining 0.0.
