We divide 86437 by 12
We want to figure out the number of times 86437 can be divided by 12.

Going ahead to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 12

Let's proceed to step 2:
12 goes into 86 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 84 away from 86, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 12

Moving on to step 3:
24 divided by 12 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 24 from 24 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 12

Going ahead to step 4:
When dividing 3 by 12, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 720.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 12

Advancing to step 5:
37 divided by 12 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 7203.0
If we take 36 away from 37, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 6:
If we divide 10 by 12, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7203.0
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 can be fit into 100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 7203.08
Deduct 96 from 100 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.

Advancing to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 7203.083
Subtract 36 from 40 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.

Going ahead to step 9:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 7203.0833
Subtracting 36 from 40 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.

Our division results in 7203.0833 with a remaining 4e-05.
