2019985 ÷ 789 
Let's see how many times 789 fits into 2019985.

Moving on to step 1:
When dividing 2 by 789, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 789

Let's proceed to step 2:
The number 789 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 789

Advancing to step 3:
789 can be fit into 201 0 times, resulting in a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 201 after subtracting 0 from 201.
Grab the next digit (9) from the dividend, add it to 201, then carry on: 2019 / 789

Let's proceed to step 4:
When dividing 2019 by 789, we get 2 with a remainder of 441.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1578 away from 2019, we end up with 441.
Append the next digit (9) from the dividend to 441 and continue with: 4419 / 789

On to step 5:
The number 789 fits into 4419 5 times, leaving a remainder of 474.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 3945 from 4419 leaves us with 474.
Include the next digit (8) from the dividend after 474, then repeat: 4748 / 789

Let's proceed to step 6:
4748 divided by 789 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
Subtracting 4734 from 4748 leaves us with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 789

On to step 7:
The number 789 fits into 145 0 times, leaving a remainder of 145.
Record the quotient 0 as the next digit in the result. 
Result so far: 2560.0
Deduct 0 from 145 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 8:
789 can be fit into 1450 1 times, resulting in a remainder of 661.
The number 1 becomes the next digit in our result. 
Result so far: 2560.1
The remainder is 661 after subtracting 789 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Moving on to step 9:
The number 789 fits into 6610 8 times, leaving a remainder of 298.
Write down 8 as next digit of the result. 
Result so far: 2560.18
The remainder is 298 after subtracting 6312 from 6610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 10:
When dividing 2980 by 789, we get 3 with a remainder of 613.
The next digit of our result is 3. 
Result so far: 2560.183
If we take 2367 away from 2980, we end up 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.

On to step 11:
789 goes into 6130 7 times with a remainder of 607.
The number 7 becomes the next digit in our result. 
Result so far: 2560.1837
Deduct 5523 from 6130 and we're left 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.

Moving on to step 12:
If we divide 6070 by 789, we get 7 and a remainder of 547.
Write down 7 as next digit of the result. 
Result so far: 2560.18377
Deduct 5523 from 6070 and we're left 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.

The final result is 2560.18377 with a remainder of 0.000547.
