We're dividing 621881 by 12 
Our goal is to divide 621881 by 12.

On to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 12

Moving on to step 2:
The number 12 fits into 62 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 60 from 62 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Step 3:
When dividing 21 by 12, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 12 from 21, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 12

Advancing to step 4:
98 divided by 12 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 518.0
If we subtract 96 from 98, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 12

Moving on to step 5:
12 can be fit into 28 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5182.0
Subtract 24 from 28 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 12

Step 6:
12 can be fit into 41 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 51823.0
If we take 36 away from 41, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 12 fits into 50 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 51823.4
If we subtract 48 from 50, we 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.

On to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 51823.41
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.

Going ahead to step 9:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 51823.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 51823.4166
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.

In conclusion, the division gives 51823.4166 with a balance of 8e-05.
