We're dividing 15927894 by 789 
We want to divide 15927894 by 789.

Advancing to step 1:
1 divided by 789 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 789

Advancing to step 2:
789 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 789

On to step 3:
When dividing 159 by 789, we get 0 with a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 159, we end up with 159.
Fetch the next digit (2) from the dividend, attach it to 159 and continue: 1592 / 789

Going ahead to step 4:
The number 789 fits into 1592 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1578 from 1592 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 789

Let's proceed to step 5:
147 divided by 789 is 0 with a remainder of 147.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 147, we end up with 147.
Grab the next digit (8) from the dividend, add it to 147, then carry on: 1478 / 789

Step 6:
789 can be fit into 1478 1 times, resulting in a remainder of 689.
Put 1 as the next digit of the answer. 
Result so far: 201.0
The remainder is 689 after subtracting 789 from 1478.
Append the next digit (9) from the dividend to 689 and continue with: 6899 / 789

Going ahead to step 7:
When dividing 6899 by 789, we get 8 with a remainder of 587.
Put 8 as the next digit of the answer. 
Result so far: 2018.0
Deduct 6312 from 6899 and we're left with 587.
Bring next digit (4) of the dividend behind the 587 and repeat the process: 5874 / 789

Advancing to step 8:
789 goes into 5874 7 times with a remainder of 351.
The next digit of our result is 7. 
Result so far: 20187.0
The remainder is 351 after subtracting 5523 from 5874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
The number 789 fits into 3510 4 times, leaving a remainder of 354.
Use 4 as the next digit of our solution. 
Result so far: 20187.4
The remainder is 354 after subtracting 3156 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 10:
3540 divided by 789 is 4 with a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 20187.44
Subtract 3156 from 3540 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

After the division, we end up with 20187.44 and a remainder of 0.384.
