789970 ÷ 12 
We're looking to find how many times 12 goes into 789970.

Going ahead to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 12

Step 2:
The number 12 fits into 78 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 72 away from 78, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

On to step 3:
12 goes into 69 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 65.0
If we take 60 away from 69, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 12

On to step 4:
12 can be fit into 99 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 658.0
Subtract 96 from 99 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 12

Advancing to step 5:
When dividing 37 by 12, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 6583.0
Deduct 36 from 37 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

On to step 6:
12 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 65830.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
12 goes into 100 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 65830.8
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 65830.83
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 65830.833
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 65830.833, and the remainder is 0.0004.
