We're dividing 78297440 by 245 
We want to divide 78297440 by 245.

Moving on to step 1:
When dividing 7 by 245, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 245

On to step 2:
If we divide 78 by 245, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 245

Let's proceed to step 3:
245 goes into 782 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 735 from 782 and we're left with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 245

Moving on to step 4:
479 divided by 245 is 1 with a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 245 from 479 to get 234.
Include the next digit (7) from the dividend after 234, then repeat: 2347 / 245

Advancing to step 5:
When dividing 2347 by 245, we get 9 with a remainder of 142.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
If we subtract 2205 from 2347, we get 142.
Take the next digit (4) from the dividend and append it to 142, then repeat: 1424 / 245

Step 6:
245 goes into 1424 5 times with a remainder of 199.
The number 5 becomes the next digit in our result. 
Result so far: 3195.0
Subtract 1225 from 1424 to get 199.
Bring next digit (4) of the dividend behind the 199 and repeat the process: 1994 / 245

Advancing to step 7:
If we divide 1994 by 245, we get 8 and a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 31958.0
Subtract 1960 from 1994 to get 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 245

Let's proceed to step 8:
If we divide 340 by 245, we get 1 and a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 319581.0
Subtract 245 from 340 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 9:
The number 245 fits into 950 3 times, leaving a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 319581.3
Deduct 735 from 950 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 10:
The number 245 fits into 2150 8 times, leaving a remainder of 190.
Record the quotient 8 as the next digit in the result. 
Result so far: 319581.38
Subtracting 1960 from 2150 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
245 can be fit into 1900 7 times, resulting in a remainder of 185.
The number 7 becomes the next digit in our result. 
Result so far: 319581.387
If we take 1715 away from 1900, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 12:
245 can be fit into 1850 7 times, resulting in a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 319581.3877
Subtracting 1715 from 1850 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final outcome is 319581.3877, with a leftover of 0.00135.
