79909010 divided by 10 
Our goal is to divide 79909010 by 10.

Moving on to step 1:
7 divided by 10 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 10

Let's proceed to step 2:
79 divided by 10 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 70 from 79 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 10

Advancing to step 3:
99 divided by 10 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtract 90 from 99 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 10

Advancing to step 4:
The number 10 fits into 90 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 799.0
Subtracting 90 from 90 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 10

Advancing to step 5:
10 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 7990.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 10

Let's proceed to step 6:
90 divided by 10 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 79909.0
If we subtract 90 from 90, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 10

On to step 7:
If we divide 1 by 10, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 799090.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 10

Going ahead to step 8:
10 goes into 10 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 7990901.0
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7990901.0
Subtract 0 from 0 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.

Moving on to step 10:
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: 7990901.0
Subtract 0 from 0 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.

The final outcome is 7990901.0, with a leftover of 0.0.
