We look at the division of 432810 by 51 
We want to figure out the number of times 432810 can be divided by 51.

Step 1:
4 divided by 51 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 51

Step 2:
When dividing 43 by 51, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 51

Moving on to step 3:
51 can be fit into 432 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 408 from 432 leaves us with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 51

Going ahead to step 4:
The number 51 fits into 248 4 times, leaving a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtract 204 from 248 to get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 51

On to step 5:
If we divide 441 by 51, we get 8 and a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 848.0
The remainder is 33 after subtracting 408 from 441.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 51

Moving on to step 6:
When dividing 330 by 51, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 8486.0
If we subtract 306 from 330, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
240 divided by 51 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 8486.4
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 8486.47
The remainder is 3 after subtracting 357 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 51, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8486.47
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 51 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 8486.4705
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
51 can be fit into 450 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 8486.47058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 51, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8486.470588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 8486.470588 and a remainder of 1.2e-06.
