14643858 ÷ 4 
Let's see how many times 4 fits into 14643858.

On to step 1:
If we divide 1 by 4, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

On to step 2:
When dividing 14 by 4, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 12 from 14 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 4

Going ahead to step 3:
If we divide 26 by 4, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 24 from 26 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 4

Going ahead to step 4:
24 divided by 4 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 366.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 4

Moving on to step 5:
3 divided by 4 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 3660.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 4

Step 6:
4 can be fit into 38 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 36609.0
The remainder is 2 after subtracting 36 from 38.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 4

Let's proceed to step 7:
The number 4 fits into 25 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 366096.0
Subtract 24 from 25 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 4

Going ahead to step 8:
The number 4 fits into 18 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 3660964.0
The remainder is 2 after subtracting 16 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3660964.5
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.

Step 10:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3660964.5
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.

Let's proceed to step 11:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3660964.5
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.

The final outcome is 3660964.5, with a leftover of 0.0.
