Let's divide 393813 by 4
We want to figure out the number of times 393813 can be divided by 4.

Going ahead to step 1:
If we divide 3 by 4, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

Moving on to step 2:
When dividing 39 by 4, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 36 from 39 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Going ahead to step 3:
The number 4 fits into 33 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 32 from 33 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

Advancing to step 4:
If we divide 18 by 4, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 984.0
If we take 16 away from 18, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 4

Let's proceed to step 5:
4 can be fit into 21 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 9845.0
The remainder is 1 after subtracting 20 from 21.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Step 6:
If we divide 13 by 4, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 98453.0
Deduct 12 from 13 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 98453.2
Subtract 8 from 10 to 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.

Let's proceed to step 8:
20 divided by 4 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 98453.25
Deduct 20 from 20 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.

Advancing to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 98453.25
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.

On to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 98453.25
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.

After the division, we end up with 98453.25 and a remainder of 0.0.
