Let's divide 345423 by 79
We want to divide 345423 by 79.

Moving on to step 1:
When dividing 3 by 79, we get 0 with 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.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 79

Let's proceed to step 2:
The number 79 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 79

On to step 3:
When dividing 345 by 79, we get 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 316 away from 345, we end up with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 79

Going ahead to step 4:
294 divided by 79 is 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 237 away from 294, we end up with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 79

Step 5:
If we divide 572 by 79, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 437.0
The remainder is 19 after subtracting 553 from 572.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 79

Advancing to step 6:
The number 79 fits into 193 2 times, leaving a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 4372.0
Deduct 158 from 193 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
79 goes into 350 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 4372.4
Subtracting 316 from 350 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
79 can be fit into 340 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 4372.44
Deduct 316 from 340 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 4372.44 with a remainder of 0.024.
