We're dividing 19579648 by 789 
Our goal is to divide 19579648 by 789.

Advancing to step 1:
The number 789 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 789

Going ahead to step 2:
789 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 789

Let's proceed to step 3:
195 divided by 789 is 0 with a remainder of 195.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 195, we end up with 195.
Grab the next digit (7) from the dividend, add it to 195, then carry on: 1957 / 789

Advancing to step 4:
If we divide 1957 by 789, we get 2 and a remainder of 379.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1578 from 1957, we get 379.
Bring next digit (9) of the dividend behind the 379 and repeat the process: 3799 / 789

Moving on to step 5:
3799 divided by 789 is 4 with a remainder of 643.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 3156 from 3799 leaves us with 643.
Grab the next digit (6) from the dividend, add it to 643, then carry on: 6436 / 789

On to step 6:
The number 789 fits into 6436 8 times, leaving a remainder of 124.
Record the quotient 8 as the next digit in the result. 
Result so far: 248.0
If we subtract 6312 from 6436, we get 124.
Include the next digit (4) from the dividend after 124, then repeat: 1244 / 789

On to step 7:
789 goes into 1244 1 times with a remainder of 455.
Record the quotient 1 as the next digit in the result. 
Result so far: 2481.0
Subtracting 789 from 1244 leaves us with 455.
Append the next digit (8) from the dividend to 455 and continue with: 4558 / 789

Advancing to step 8:
If we divide 4558 by 789, we get 5 and a remainder of 613.
Write down 5 as next digit of the result. 
Result so far: 24815.0
Subtracting 3945 from 4558 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Let's proceed to step 9:
When dividing 6130 by 789, we get 7 with a remainder of 607.
Record the quotient 7 as the next digit in the result. 
Result so far: 24815.7
If we take 5523 away from 6130, we end up with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Advancing to step 10:
When dividing 6070 by 789, we get 7 with a remainder of 547.
Put 7 as the next digit of the answer. 
Result so far: 24815.77
Subtracting 5523 from 6070 leaves us with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

After the division, we end up with 24815.77 and a remainder of 0.547.
