578989 ÷ 79 
Our goal is to divide 578989 by 79.

On to step 1:
79 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 79

Advancing to step 2:
79 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 79

Advancing to step 3:
79 goes into 578 7 times with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 553 from 578, we get 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 79

Let's proceed to step 4:
If we divide 259 by 79, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we take 237 away from 259, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 79

Moving on to step 5:
79 goes into 228 2 times with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 732.0
Deduct 158 from 228 and we're left with 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 79

On to step 6:
709 divided by 79 is 8 with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 7328.0
If we subtract 632 from 709, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
The number 79 fits into 770 9 times, leaving a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 7328.9
Subtracting 711 from 770 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
79 goes into 590 7 times with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 7328.97
The remainder is 37 after subtracting 553 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
370 divided by 79 is 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 7328.974
Subtracting 316 from 370 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
If we divide 540 by 79, we get 6 and a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 7328.9746
Subtract 474 from 540 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
660 divided by 79 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 7328.97468
The remainder is 28 after subtracting 632 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
280 divided by 79 is 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 7328.974683
The remainder is 43 after subtracting 237 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
If we divide 430 by 79, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 7328.9746835
Subtracting 395 from 430 leaves us 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.

Advancing to step 14:
79 goes into 350 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 7328.97468354
Deduct 316 from 350 and we're left 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.

In conclusion, the division gives 7328.97468354 with a balance of 3.4e-08.
