Let's divide 312433 by 78
We want to figure out the number of times 312433 can be divided by 78.

Step 1:
3 divided by 78 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 78

Advancing to step 2:
The number 78 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 78

Let's proceed to step 3:
78 goes into 312 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 0 after subtracting 312 from 312.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 78

Step 4:
When dividing 4 by 78, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 78

Let's proceed to step 5:
43 divided by 78 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 400.0
If we subtract 0 from 43, we get 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 78

Let's proceed to step 6:
When dividing 433 by 78, we get 5 with a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 4005.0
Subtract 390 from 433 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
When dividing 430 by 78, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 4005.5
Deduct 390 from 430 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 78 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4005.55
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 4005.55 and a remainder of 0.01.
