We divide 429520 by 4
We want to figure out the number of times 429520 can be divided by 4.

Moving on to step 1:
When dividing 4 by 4, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 4 from 4 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 4

On to step 2:
4 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 4

Step 3:
4 can be fit into 29 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 107.0
Subtracting 28 from 29 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 4

Step 4:
15 divided by 4 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1073.0
Subtracting 12 from 15 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Advancing to step 5:
32 divided by 4 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 10738.0
If we subtract 32 from 32, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Going ahead to step 6:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 107380.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 107380.0
The remainder is 0 after subtracting 0 from 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:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 107380.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 107380.0 with a remainder of 0.0.
