63089609 ÷ 12 
We want to divide 63089609 by 12.

Advancing to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

On to step 2:
When dividing 63 by 12, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 60 from 63, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 12

Let's proceed to step 3:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 24 from 30, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 12

Advancing to step 4:
When dividing 68 by 12, we get 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 525.0
Subtract 60 from 68 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

On to step 5:
If we divide 89 by 12, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 5257.0
If we subtract 84 from 89, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 12

Moving on to step 6:
12 can be fit into 56 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 52574.0
Deduct 48 from 56 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

On to step 7:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 525746.0
Subtracting 72 from 80 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 12

Moving on to step 8:
12 goes into 89 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 5257467.0
The remainder is 5 after subtracting 84 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
When dividing 50 by 12, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 5257467.4
Deduct 48 from 50 and we're left with 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 10:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 5257467.41
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.

Let's proceed to step 11:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 5257467.416
Deduct 72 from 80 and we're left 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.

Moving on to step 12:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 5257467.4166
Deduct 72 from 80 and we're left 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 5257467.4166 with a balance of 8e-05.
