816427 ÷ 51 
Our goal is to divide 816427 by 51.

On to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 51

Advancing to step 2:
51 can be fit into 81 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 30 after subtracting 51 from 81.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 51

Going ahead to step 3:
306 divided by 51 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 306 away from 306, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 51

Going ahead to step 4:
51 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 160.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 51

Let's proceed to step 5:
51 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 1600.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 51

On to step 6:
When dividing 427 by 51, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 16008.0
Subtracting 408 from 427 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 51, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 16008.3
Subtract 153 from 190 to 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 8:
When dividing 370 by 51, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 16008.37
If we take 357 away from 370, we end up with 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 9:
51 goes into 130 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 16008.372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 16008.3725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
250 divided by 51 is 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 16008.37254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
When dividing 460 by 51, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 16008.372549
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
51 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 16008.372549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
When dividing 100 by 51, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 16008.37254901
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

In conclusion, the division gives 16008.37254901 with a balance of 4.9e-08.
