398770 divided by 16 
Let's see how many times 16 fits into 398770.

Advancing to step 1:
The number 16 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 16

Let's proceed to step 2:
The number 16 fits into 39 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 32 from 39 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 16

Moving on to step 3:
When dividing 78 by 16, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 64 from 78 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 16

Let's proceed to step 4:
147 divided by 16 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 249.0
The remainder is 3 after subtracting 144 from 147.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 16

Moving on to step 5:
The number 16 fits into 37 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2492.0
If we take 32 away from 37, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 16

On to step 6:
16 goes into 50 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 24923.0
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
16 goes into 20 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 24923.1
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 16 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 24923.12
If we subtract 32 from 40, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 16 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 24923.125
Deduct 80 from 80 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.

Let's proceed to step 10:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24923.125
If we subtract 0 from 0, 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.

Let's proceed to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 24923.125
If we subtract 0 from 0, 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.

The final result is 24923.125 with a remainder of 0.0.
