We look at the division of 428129 by 5 
Our goal is to divide 428129 by 5.

On to step 1:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 5

Moving on to step 2:
If we divide 42 by 5, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 2 after subtracting 40 from 42.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 5

Going ahead to step 3:
When dividing 28 by 5, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 3 after subtracting 25 from 28.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 5

On to step 4:
If we divide 31 by 5, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
The remainder is 1 after subtracting 30 from 31.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 5

Let's proceed to step 5:
The number 5 fits into 12 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 8562.0
The remainder is 2 after subtracting 10 from 12.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 5

Let's proceed to step 6:
5 goes into 29 5 times with a remainder of 4.
The next digit of our result is 5. 
Result so far: 85625.0
Subtract 25 from 29 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
5 can be fit into 40 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 85625.8
Deduct 40 from 40 and we're left 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.

Advancing to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 85625.8
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.

Moving on to step 9:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 85625.8
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.

The final result is 85625.8 with a remainder of 0.0.
