We divide 743856 by 4
Let's see how many times 4 fits into 743856.

On to step 1:
4 can be fit into 7 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 4 from 7.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

Step 2:
4 can be fit into 34 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 2 after subtracting 32 from 34.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

Advancing to step 3:
When dividing 23 by 4, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 185.0
Deduct 20 from 23 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 4

On to step 4:
The number 4 fits into 38 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1859.0
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 5:
25 divided by 4 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 18596.0
If we take 24 away from 25, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 4

On to step 6:
4 goes into 16 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 185964.0
Deduct 16 from 16 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.

On to step 7:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 185964.0
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 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 185964.0
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.

The final outcome is 185964.0, with a leftover of 0.0.
