Let's divide 629978 by 79
We want to divide 629978 by 79.

On to step 1:
6 divided by 79 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 79

Let's proceed to step 2:
When dividing 62 by 79, we get 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 79

Let's proceed to step 3:
When dividing 629 by 79, we get 7 with a remainder of 76.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 553 from 629 to get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 79

On to step 4:
If we divide 769 by 79, we get 9 and a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 711 from 769 leaves us with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 79

Advancing to step 5:
587 divided by 79 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 797.0
If we subtract 553 from 587, we get 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 79

Let's proceed to step 6:
79 goes into 348 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 7974.0
If we take 316 away from 348, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
79 can be fit into 320 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 7974.4
If we subtract 316 from 320, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 79 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7974.4
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 79 fits into 400 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7974.405
If we subtract 395 from 400, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
79 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7974.405
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 79, we get 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 7974.40506
The remainder is 26 after subtracting 474 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
When dividing 260 by 79, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 7974.405063
If we subtract 237 from 260, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 13:
79 can be fit into 230 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 7974.4050632
If we subtract 158 from 230, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
The number 79 fits into 720 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 7974.40506329
If we take 711 away from 720, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 7974.40506329 with a balance of 9e-09.
