14390233 ÷ 778 
Let's see how many times 778 fits into 14390233.

Moving on to step 1:
1 divided by 778 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 778

Let's proceed to step 2:
If we divide 14 by 778, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 778

Advancing to step 3:
The number 778 fits into 143 0 times, leaving a remainder of 143.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 143, we get 143.
Grab the next digit (9) from the dividend, add it to 143, then carry on: 1439 / 778

Advancing to step 4:
If we divide 1439 by 778, we get 1 and a remainder of 661.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 661 after subtracting 778 from 1439.
Append the next digit (0) from the dividend to 661 and continue with: 6610 / 778

Let's proceed to step 5:
If we divide 6610 by 778, we get 8 and a remainder of 386.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 6224 from 6610 leaves us with 386.
Take the next digit (2) from the dividend and append it to 386, then repeat: 3862 / 778

Moving on to step 6:
3862 divided by 778 is 4 with a remainder of 750.
Put 4 as the next digit of the answer. 
Result so far: 184.0
Subtracting 3112 from 3862 leaves us with 750.
Bring next digit (3) of the dividend behind the 750 and repeat the process: 7503 / 778

Advancing to step 7:
The number 778 fits into 7503 9 times, leaving a remainder of 501.
The number 9 becomes the next digit in our result. 
Result so far: 1849.0
Deduct 7002 from 7503 and we're left with 501.
Grab the next digit (3) from the dividend, add it to 501, then carry on: 5013 / 778

Advancing to step 8:
When dividing 5013 by 778, we get 6 with a remainder of 345.
Write down 6 as next digit of the result. 
Result so far: 18496.0
If we subtract 4668 from 5013, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 9:
The number 778 fits into 3450 4 times, leaving a remainder of 338.
The number 4 becomes the next digit in our result. 
Result so far: 18496.4
Subtract 3112 from 3450 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 10:
3380 divided by 778 is 4 with a remainder of 268.
Record the quotient 4 as the next digit in the result. 
Result so far: 18496.44
Subtract 3112 from 3380 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 18496.44 with a remainder of 0.268.
