623979 ÷ 10 
Our goal is to divide 623979 by 10.

Going ahead to step 1:
The number 10 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 10

Step 2:
If we divide 62 by 10, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 60 from 62, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 10

Advancing to step 3:
23 divided by 10 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 62.0
If we subtract 20 from 23, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 10

Step 4:
10 goes into 39 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 623.0
If we take 30 away from 39, we end up with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 10

Moving on to step 5:
10 can be fit into 97 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 6239.0
If we take 90 away from 97, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 10

Step 6:
When dividing 79 by 10, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 62397.0
Deduct 70 from 79 and we're left 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.

On to step 7:
90 divided by 10 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 62397.9
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 62397.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 62397.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 62397.9 and a remainder of 0.0.
