We divide 78090268 by 321
Let's see how many times 321 fits into 78090268.

Moving on to step 1:
When dividing 7 by 321, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 321

Moving on to step 2:
321 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 321

Let's proceed to step 3:
321 goes into 780 2 times with a remainder of 138.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 642 from 780 leaves us with 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 321

Moving on to step 4:
321 can be fit into 1389 4 times, resulting in a remainder of 105.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 1284 away from 1389, we end up with 105.
Bring next digit (0) of the dividend behind the 105 and repeat the process: 1050 / 321

Going ahead to step 5:
321 goes into 1050 3 times with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
If we subtract 963 from 1050, we get 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 321

Step 6:
872 divided by 321 is 2 with a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 2432.0
If we subtract 642 from 872, we get 230.
Include the next digit (6) from the dividend after 230, then repeat: 2306 / 321

Advancing to step 7:
2306 divided by 321 is 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 24327.0
If we take 2247 away from 2306, we end up with 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 321

Moving on to step 8:
321 can be fit into 598 1 times, resulting in a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 243271.0
If we subtract 321 from 598, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Going ahead to step 9:
If we divide 2770 by 321, we get 8 and a remainder of 202.
Write down 8 as next digit of the result. 
Result so far: 243271.8
Subtract 2568 from 2770 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
If we divide 2020 by 321, we get 6 and a remainder of 94.
The next digit of our result is 6. 
Result so far: 243271.86
The remainder is 94 after subtracting 1926 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 11:
321 goes into 940 2 times with a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 243271.862
If we take 642 away from 940, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 12:
321 goes into 2980 9 times with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 243271.8629
Subtracting 2889 from 2980 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 13:
321 goes into 910 2 times with a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 243271.86292
If we take 642 away from 910, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 14:
When dividing 2680 by 321, we get 8 with a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 243271.862928
Subtract 2568 from 2680 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
321 goes into 1120 3 times with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 243271.8629283
If we take 963 away from 1120, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 16:
When dividing 1570 by 321, we get 4 with a remainder of 286.
Use 4 as the next digit of our solution. 
Result so far: 243271.86292834
Deduct 1284 from 1570 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final outcome is 243271.86292834, with a leftover of 2.86e-07.
