Let's divide 20405840 by 476
Our goal is to divide 20405840 by 476.

Step 1:
476 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 476

Let's proceed to step 2:
When dividing 20 by 476, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 476

On to step 3:
476 can be fit into 204 0 times, resulting in a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 204 and we're left with 204.
Bring next digit (0) of the dividend behind the 204 and repeat the process: 2040 / 476

Moving on to step 4:
If we divide 2040 by 476, we get 4 and a remainder of 136.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1904 from 2040 and we're left with 136.
Bring next digit (5) of the dividend behind the 136 and repeat the process: 1365 / 476

Advancing to step 5:
476 can be fit into 1365 2 times, resulting in a remainder of 413.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 952 away from 1365, we end up with 413.
Append the next digit (8) from the dividend to 413 and continue with: 4138 / 476

Step 6:
If we divide 4138 by 476, we get 8 and a remainder of 330.
Use 8 as the next digit of our solution. 
Result so far: 428.0
The remainder is 330 after subtracting 3808 from 4138.
Fetch the next digit (4) from the dividend, attach it to 330 and continue: 3304 / 476

Advancing to step 7:
476 goes into 3304 6 times with a remainder of 448.
Record the quotient 6 as the next digit in the result. 
Result so far: 4286.0
Subtracting 2856 from 3304 leaves us with 448.
Include the next digit (0) from the dividend after 448, then repeat: 4480 / 476

Moving on to step 8:
476 goes into 4480 9 times with a remainder of 196.
Record the quotient 9 as the next digit in the result. 
Result so far: 42869.0
Deduct 4284 from 4480 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 9:
1960 divided by 476 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 42869.4
If we take 1904 away from 1960, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
476 can be fit into 560 1 times, resulting in a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 42869.41
The remainder is 84 after subtracting 476 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
The number 476 fits into 840 1 times, leaving a remainder of 364.
Record the quotient 1 as the next digit in the result. 
Result so far: 42869.411
If we subtract 476 from 840, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

In conclusion, the division gives 42869.411 with a balance of 0.0364.
