80400799 ÷ 325 
Let's see how many times 325 fits into 80400799.

Let's proceed to step 1:
The number 325 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
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 / 325

Going ahead to step 2:
When dividing 80 by 325, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 325

Advancing to step 3:
804 divided by 325 is 2 with a remainder of 154.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 650 from 804 to get 154.
Take the next digit (0) from the dividend and append it to 154, then repeat: 1540 / 325

Let's proceed to step 4:
When dividing 1540 by 325, we get 4 with a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 1300 from 1540, we get 240.
Fetch the next digit (0) from the dividend, attach it to 240 and continue: 2400 / 325

Going ahead to step 5:
If we divide 2400 by 325, we get 7 and a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 247.0
Subtracting 2275 from 2400 leaves us with 125.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 325

Advancing to step 6:
When dividing 1257 by 325, we get 3 with a remainder of 282.
The number 3 becomes the next digit in our result. 
Result so far: 2473.0
Subtracting 975 from 1257 leaves us with 282.
Fetch the next digit (9) from the dividend, attach it to 282 and continue: 2829 / 325

Advancing to step 7:
2829 divided by 325 is 8 with a remainder of 229.
The number 8 becomes the next digit in our result. 
Result so far: 24738.0
Deduct 2600 from 2829 and we're left with 229.
Fetch the next digit (9) from the dividend, attach it to 229 and continue: 2299 / 325

Going ahead to step 8:
325 goes into 2299 7 times with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 247387.0
The remainder is 24 after subtracting 2275 from 2299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
325 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 247387.0
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
The number 325 fits into 2400 7 times, leaving a remainder of 125.
Use 7 as the next digit of our solution. 
Result so far: 247387.07
Subtracting 2275 from 2400 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 11:
1250 divided by 325 is 3 with a remainder of 275.
The next digit of our result is 3. 
Result so far: 247387.073
Subtracting 975 from 1250 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 12:
When dividing 2750 by 325, we get 8 with a remainder of 150.
The next digit of our result is 8. 
Result so far: 247387.0738
If we take 2600 away from 2750, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
325 can be fit into 1500 4 times, resulting in a remainder of 200.
The next digit of our result is 4. 
Result so far: 247387.07384
The remainder is 200 after subtracting 1300 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
The number 325 fits into 2000 6 times, leaving a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 247387.073846
Subtract 1950 from 2000 to 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.

On to step 15:
325 can be fit into 500 1 times, resulting in a remainder of 175.
Record the quotient 1 as the next digit in the result. 
Result so far: 247387.0738461
Deduct 325 from 500 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 16:
The number 325 fits into 1750 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 247387.07384615
If we subtract 1625 from 1750, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 247387.07384615 with a remaining 1.25e-07.
