We're dividing 80399329 by 52 
We want to figure out the number of times 80399329 can be divided by 52.

Going ahead to step 1:
The number 52 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 52

Going ahead to step 2:
80 divided by 52 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 52 from 80 to get 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 52

Going ahead to step 3:
The number 52 fits into 283 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 23 after subtracting 260 from 283.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 52

Going ahead to step 4:
52 goes into 239 4 times with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 154.0
The remainder is 31 after subtracting 208 from 239.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 52

Advancing to step 5:
If we divide 319 by 52, we get 6 and a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 1546.0
Deduct 312 from 319 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 52

Step 6:
The number 52 fits into 73 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 15461.0
If we take 52 away from 73, we end up with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 52

On to step 7:
212 divided by 52 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 154614.0
If we take 208 away from 212, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 52

Moving on to step 8:
The number 52 fits into 49 0 times, leaving a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 1546140.0
Subtract 0 from 49 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.

Advancing to step 9:
The number 52 fits into 490 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 1546140.9
Deduct 468 from 490 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
220 divided by 52 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 1546140.94
The remainder is 12 after subtracting 208 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 52, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1546140.942
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
The number 52 fits into 160 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1546140.9423
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
The number 52 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1546140.9423
Subtract 0 from 40 to 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 14:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 1546140.942307
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 15:
52 goes into 360 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 1546140.9423076
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 1546140.94230769
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1546140.94230769 with a remainder of 1.2e-08.
