643133 ÷ 12 
We want to divide 643133 by 12.

Advancing to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

On to step 2:
The number 12 fits into 64 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 60 from 64 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 12

Let's proceed to step 3:
12 can be fit into 43 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 36 from 43 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 12

Moving on to step 4:
71 divided by 12 is 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 535.0
If we subtract 60 from 71, we get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 12

Let's proceed to step 5:
113 divided by 12 is 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 5359.0
Subtracting 108 from 113 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 12

Let's proceed to step 6:
12 can be fit into 53 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 53594.0
The remainder is 5 after subtracting 48 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 12, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 53594.4
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 53594.41
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 53594.416
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 53594.4166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 53594.4166 with a balance of 8e-05.
