851530 divided by 12 
We want to divide 851530 by 12.

Moving on to step 1:
8 divided by 12 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 12

Step 2:
The number 12 fits into 85 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 84 from 85, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 12

Moving on to step 3:
12 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 12

Advancing to step 4:
When dividing 115 by 12, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 709.0
Deduct 108 from 115 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 12

Moving on to step 5:
The number 12 fits into 73 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 7096.0
The remainder is 1 after subtracting 72 from 73.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

Going ahead to step 6:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 70960.0
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.

Let's proceed to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 70960.8
Subtracting 96 from 100 leaves us 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.

Advancing to step 8:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 70960.83
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.

Going ahead to step 9:
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: 70960.833
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 70960.833, and the remainder is 0.0004.
