428829 divided by 51 
Our goal is to divide 428829 by 51.

Moving on to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 51

Advancing to step 2:
51 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 51

Let's proceed to step 3:
When dividing 428 by 51, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 408 from 428 to get 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 51

On to step 4:
51 can be fit into 208 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtract 204 from 208 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 51

Moving on to step 5:
When dividing 42 by 51, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 840.0
If we take 0 away from 42, we end up with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 51

Moving on to step 6:
When dividing 429 by 51, we get 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 8408.0
Subtract 408 from 429 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 8408.4
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 51 fits into 60 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 8408.41
If we take 51 away from 60, we end up 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.

Advancing to step 9:
51 can be fit into 90 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 8408.411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 8408.411 with a remaining 0.0039.
