809546 ÷ 51 
Our goal is to divide 809546 by 51.

Advancing to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 51

Moving on to step 2:
When dividing 80 by 51, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 80, we end up with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 51

Advancing to step 3:
51 goes into 299 5 times with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 255 from 299 to get 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 51

Going ahead to step 4:
445 divided by 51 is 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we subtract 408 from 445, we get 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 51

Going ahead to step 5:
When dividing 374 by 51, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1587.0
Subtracting 357 from 374 leaves us with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 51

On to step 6:
51 goes into 176 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 15873.0
Subtract 153 from 176 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
230 divided by 51 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 15873.4
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
51 goes into 260 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15873.45
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 15873.45
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
51 goes into 500 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 15873.4509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15873.45098
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
51 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 15873.45098
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
When dividing 200 by 51, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 15873.4509803
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 15873.45098039
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 15873.45098039, with a leftover of 1.1e-08.
