We look at the division of 846861 by 12 
Let's see how many times 12 fits into 846861.

Advancing 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
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 12

Step 2:
12 goes into 84 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 84 away from 84, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 12

Going ahead to step 3:
6 divided by 12 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 12

Going ahead to step 4:
68 divided by 12 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 705.0
Subtract 60 from 68 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 12

Step 5:
12 can be fit into 86 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7057.0
Deduct 84 from 86 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 12

Let's proceed to step 6:
When dividing 21 by 12, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 70571.0
The remainder is 9 after subtracting 12 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 70571.7
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
12 goes into 60 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 70571.75
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 70571.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 70571.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 70571.75, and the remainder is 0.0.
