We divide 578869 by 79
We want to figure out the number of times 578869 can be divided by 79.

On to step 1:
If we divide 5 by 79, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 79

On to step 2:
When dividing 57 by 79, we get 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 79

Let's proceed to step 3:
When dividing 578 by 79, we get 7 with a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 553 from 578, we get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 79

Moving on to step 4:
When dividing 258 by 79, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 237 away from 258, we end up with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 79

Moving on to step 5:
The number 79 fits into 216 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 732.0
Subtract 158 from 216 to get 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 79

Step 6:
79 goes into 589 7 times with a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 7327.0
Subtract 553 from 589 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
79 goes into 360 4 times with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 7327.4
Deduct 316 from 360 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
If we divide 440 by 79, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 7327.45
Subtracting 395 from 440 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
450 divided by 79 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 7327.455
If we subtract 395 from 450, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 7327.455, and the remainder is 0.0055.
