809345 divided by 51 
We're looking to find how many times 51 goes into 809345.

Moving on to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 51

Let's proceed to step 2:
If we divide 80 by 51, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 29 after subtracting 51 from 80.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 51

Advancing to step 3:
The number 51 fits into 299 5 times, leaving a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 255 from 299 and we're left with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 51

On to step 4:
51 can be fit into 443 8 times, resulting in a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtract 408 from 443 to get 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 51

Step 5:
When dividing 354 by 51, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 1586.0
The remainder is 48 after subtracting 306 from 354.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 51

Advancing to step 6:
The number 51 fits into 485 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 15869.0
If we subtract 459 from 485, 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.

Going ahead to step 7:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15869.5
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 51, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 15869.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
51 goes into 500 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 15869.509
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
51 can be fit into 410 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15869.5098
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.

Let's proceed to step 11:
If we divide 20 by 51, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15869.5098
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.

Going ahead to step 12:
If we divide 200 by 51, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 15869.509803
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.

Moving on to step 13:
When dividing 470 by 51, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 15869.5098039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
The number 51 fits into 110 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 15869.50980392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 15869.50980392 and a remainder of 8e-09.
