Let's divide 400820 by 16
We're looking to find how many times 16 goes into 400820.

Let's proceed to step 1:
4 divided by 16 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 16

Let's proceed to step 2:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 32 from 40 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 16

Moving on to step 3:
16 goes into 80 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 80 from 80, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 16

Advancing to step 4:
16 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 250.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 16

Going ahead to step 5:
When dividing 82 by 16, we get 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 2505.0
If we subtract 80 from 82, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 16

Advancing to step 6:
When dividing 20 by 16, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 25051.0
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
16 goes into 40 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 25051.2
Deduct 32 from 40 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 25051.25
If we subtract 80 from 80, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25051.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25051.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 25051.25 with a balance of 0.0.
