We're dividing 25214667 by 78 
We want to divide 25214667 by 78.

On to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 78

Step 2:
78 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 78

On to step 3:
The number 78 fits into 252 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 234 from 252 to get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 78

Going ahead to step 4:
78 can be fit into 181 2 times, resulting in a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 156 from 181, we get 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 78

Going ahead to step 5:
78 goes into 254 3 times with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 323.0
The remainder is 20 after subtracting 234 from 254.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 78

Step 6:
78 goes into 206 2 times with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 3232.0
Deduct 156 from 206 and we're left with 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 78

Step 7:
The number 78 fits into 506 6 times, leaving a remainder of 38.
The next digit of our result is 6. 
Result so far: 32326.0
If we subtract 468 from 506, we get 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 78

Moving on to step 8:
78 goes into 387 4 times with a remainder of 75.
The next digit of our result is 4. 
Result so far: 323264.0
Subtract 312 from 387 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
The number 78 fits into 750 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 323264.9
The remainder is 48 after subtracting 702 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 323264.96
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 78 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 323264.961
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
When dividing 420 by 78, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 323264.9615
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
If we divide 300 by 78, we get 3 and a remainder of 66.
The next digit of our result is 3. 
Result so far: 323264.96153
Deduct 234 from 300 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
78 goes into 660 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 323264.961538
Subtract 624 from 660 to 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.

Moving on to step 15:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 323264.9615384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
If we divide 480 by 78, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 323264.96153846
Subtracting 468 from 480 leaves us with 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 323264.96153846 with a remainder of 1.2e-08.
