809991 divided by 52 
We're looking to find how many times 52 goes into 809991.

Step 1:
52 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
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 52

Advancing to step 2:
When dividing 80 by 52, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 52 from 80 to get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 52

Advancing to step 3:
When dividing 289 by 52, we get 5 with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 260 away from 289, we end up with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 52

Let's proceed to step 4:
If we divide 299 by 52, we get 5 and a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
The remainder is 39 after subtracting 260 from 299.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 52

Going ahead to step 5:
When dividing 399 by 52, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 1557.0
Subtracting 364 from 399 leaves us with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 52

Advancing to step 6:
52 goes into 351 6 times with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 15576.0
Subtracting 312 from 351 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
If we divide 390 by 52, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 15576.7
Subtracting 364 from 390 leaves us with 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:
52 goes into 260 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15576.75
Subtracting 260 from 260 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 52, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15576.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
52 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15576.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 15576.75, with a leftover of 0.0.
