We're dividing 31428568 by 781 
We want to divide 31428568 by 781.

On to step 1:
When dividing 3 by 781, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 781

Step 2:
The number 781 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 781

Step 3:
When dividing 314 by 781, we get 0 with a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 314 and we're left with 314.
Append the next digit (2) from the dividend to 314 and continue with: 3142 / 781

Moving on to step 4:
3142 divided by 781 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 3124 from 3142 to get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 781

Step 5:
781 can be fit into 188 0 times, resulting in a remainder of 188.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 188 after subtracting 0 from 188.
Include the next digit (5) from the dividend after 188, then repeat: 1885 / 781

Going ahead to step 6:
781 goes into 1885 2 times with a remainder of 323.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
Subtract 1562 from 1885 to get 323.
Include the next digit (6) from the dividend after 323, then repeat: 3236 / 781

Step 7:
The number 781 fits into 3236 4 times, leaving a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 4024.0
If we subtract 3124 from 3236, we get 112.
Grab the next digit (8) from the dividend, add it to 112, then carry on: 1128 / 781

Let's proceed to step 8:
When dividing 1128 by 781, we get 1 with a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 40241.0
If we subtract 781 from 1128, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 9:
781 goes into 3470 4 times with a remainder of 346.
Put 4 as the next digit of the answer. 
Result so far: 40241.4
The remainder is 346 after subtracting 3124 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 10:
The number 781 fits into 3460 4 times, leaving a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 40241.44
Deduct 3124 from 3460 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

In conclusion, the division gives 40241.44 with a balance of 0.336.
