We divide 78411643 by 321
Let's see how many times 321 fits into 78411643.

Going ahead to step 1:
7 divided by 321 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 321

Moving on to step 2:
The number 321 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 321

Going ahead to step 3:
784 divided by 321 is 2 with a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 642 away from 784, we end up with 142.
Include the next digit (1) from the dividend after 142, then repeat: 1421 / 321

Going ahead to step 4:
When dividing 1421 by 321, we get 4 with a remainder of 137.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 1284 from 1421 to get 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 321

Moving on to step 5:
When dividing 1371 by 321, we get 4 with a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 244.0
If we take 1284 away from 1371, we end up with 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 321

Let's proceed to step 6:
321 goes into 876 2 times with a remainder of 234.
Use 2 as the next digit of our solution. 
Result so far: 2442.0
The remainder is 234 after subtracting 642 from 876.
Include the next digit (4) from the dividend after 234, then repeat: 2344 / 321

Let's proceed to step 7:
When dividing 2344 by 321, we get 7 with a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 24427.0
Subtract 2247 from 2344 to get 97.
Include the next digit (3) from the dividend after 97, then repeat: 973 / 321

On to step 8:
321 can be fit into 973 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 244273.0
The remainder is 10 after subtracting 963 from 973.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 321 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 244273.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
The number 321 fits into 1000 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 244273.03
Subtract 963 from 1000 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
321 can be fit into 370 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 244273.031
The remainder is 49 after subtracting 321 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 12:
The number 321 fits into 490 1 times, leaving a remainder of 169.
Use 1 as the next digit of our solution. 
Result so far: 244273.0311
Subtracting 321 from 490 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

In conclusion, the division gives 244273.0311 with a balance of 0.00169.
