Let's divide 28646431 by 78
Let's see how many times 78 fits into 28646431.

Let's proceed to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 78

Advancing to step 2:
78 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 78

Going ahead to step 3:
If we divide 286 by 78, we get 3 and a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 52 after subtracting 234 from 286.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 78

Advancing to step 4:
If we divide 524 by 78, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 468 from 524 leaves us with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 78

Advancing to step 5:
78 can be fit into 566 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 367.0
Deduct 546 from 566 and we're left with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 78

On to step 6:
78 goes into 204 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 3672.0
If we take 156 away from 204, we end up with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 78

Let's proceed to step 7:
If we divide 483 by 78, we get 6 and a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 36726.0
If we subtract 468 from 483, we get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 78

Going ahead to step 8:
78 goes into 151 1 times with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 367261.0
Subtract 78 from 151 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
If we divide 730 by 78, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 367261.9
Subtract 702 from 730 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
When dividing 280 by 78, we get 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 367261.93
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 367261.935
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
78 goes into 700 8 times with a remainder of 76.
The next digit of our result is 8. 
Result so far: 367261.9358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
When dividing 760 by 78, we get 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 367261.93589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
78 can be fit into 580 7 times, resulting in a remainder of 34.
The next digit of our result is 7. 
Result so far: 367261.935897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 15:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 367261.9358974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
When dividing 280 by 78, we get 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 367261.93589743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 367261.93589743, and the remainder is 4.6e-08.
