Let's divide 20256438 by 412
We're looking to find how many times 412 goes into 20256438.

On to step 1:
412 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 412

On to step 2:
If we divide 20 by 412, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 412

Let's proceed to step 3:
412 can be fit into 202 0 times, resulting in a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 202, we end up with 202.
Fetch the next digit (5) from the dividend, attach it to 202 and continue: 2025 / 412

Advancing to step 4:
The number 412 fits into 2025 4 times, leaving a remainder of 377.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1648 from 2025, we get 377.
Grab the next digit (6) from the dividend, add it to 377, then carry on: 3776 / 412

On to step 5:
412 can be fit into 3776 9 times, resulting in a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 3708 from 3776 and we're left with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 412

Step 6:
412 can be fit into 684 1 times, resulting in a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 491.0
If we take 412 away from 684, we end up with 272.
Append the next digit (3) from the dividend to 272 and continue with: 2723 / 412

Going ahead to step 7:
2723 divided by 412 is 6 with a remainder of 251.
The number 6 becomes the next digit in our result. 
Result so far: 4916.0
Subtracting 2472 from 2723 leaves us with 251.
Grab the next digit (8) from the dividend, add it to 251, then carry on: 2518 / 412

Let's proceed to step 8:
When dividing 2518 by 412, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 49166.0
Subtracting 2472 from 2518 leaves us 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.

Step 9:
The number 412 fits into 460 1 times, leaving a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 49166.1
Deduct 412 from 460 and we're left 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 10:
412 can be fit into 480 1 times, resulting in a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 49166.11
If we take 412 away from 480, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 49166.11 with a remaining 0.068.
