We look at the division of 436345 by 51 
Let's see how many times 51 fits into 436345.

Going ahead to step 1:
51 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 51

Moving on to step 2:
43 divided by 51 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 51

Moving on to step 3:
51 can be fit into 436 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 408 from 436 and we're left with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 51

Moving on to step 4:
If we divide 283 by 51, we get 5 and a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we take 255 away from 283, we end up with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 51

Let's proceed to step 5:
51 can be fit into 284 5 times, resulting in a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 855.0
The remainder is 29 after subtracting 255 from 284.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 51

Step 6:
If we divide 295 by 51, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 8555.0
If we subtract 255 from 295, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
400 divided by 51 is 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 8555.7
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8555.78
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
The number 51 fits into 220 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 8555.784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
51 can be fit into 160 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8555.7843
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
51 goes into 70 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8555.78431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 8555.784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 8555.7843137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
51 goes into 130 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 8555.78431372
If we take 102 away from 130, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 8555.78431372 with a remaining 2.8e-08.
