20433191 ÷ 678 
We want to divide 20433191 by 678.

On to step 1:
678 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 678

Moving on to step 2:
678 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 678

Going ahead to step 3:
678 goes into 204 0 times with a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 204 after subtracting 0 from 204.
Fetch the next digit (3) from the dividend, attach it to 204 and continue: 2043 / 678

On to step 4:
2043 divided by 678 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2034 from 2043 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 678

Advancing to step 5:
If we divide 93 by 678, we get 0 and a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 93 leaves us with 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 678

Going ahead to step 6:
678 goes into 931 1 times with a remainder of 253.
The next digit of our result is 1. 
Result so far: 301.0
Subtract 678 from 931 to get 253.
Take the next digit (9) from the dividend and append it to 253, then repeat: 2539 / 678

Going ahead to step 7:
When dividing 2539 by 678, we get 3 with a remainder of 505.
Put 3 as the next digit of the answer. 
Result so far: 3013.0
If we take 2034 away from 2539, we end up with 505.
Append the next digit (1) from the dividend to 505 and continue with: 5051 / 678

Going ahead to step 8:
5051 divided by 678 is 7 with a remainder of 305.
Put 7 as the next digit of the answer. 
Result so far: 30137.0
If we take 4746 away from 5051, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
3050 divided by 678 is 4 with a remainder of 338.
The number 4 becomes the next digit in our result. 
Result so far: 30137.4
Subtracting 2712 from 3050 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 10:
If we divide 3380 by 678, we get 4 and a remainder of 668.
Use 4 as the next digit of our solution. 
Result so far: 30137.44
Subtract 2712 from 3380 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

In conclusion, the division gives 30137.44 with a balance of 0.668.
