We divide 53965565 by 12
We want to divide 53965565 by 12.

On to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 12

Moving on to step 2:
12 can be fit into 53 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 48 from 53 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

Going ahead to step 3:
12 goes into 59 4 times with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 48 from 59, we get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Moving on to step 4:
If we divide 116 by 12, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 449.0
If we take 108 away from 116, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 12

Advancing to step 5:
12 can be fit into 85 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 4497.0
Subtracting 84 from 85 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 12

Moving on to step 6:
If we divide 15 by 12, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 44971.0
The remainder is 3 after subtracting 12 from 15.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 12

Advancing to step 7:
When dividing 36 by 12, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 449713.0
Subtracting 36 from 36 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 12

Advancing to step 8:
If we divide 5 by 12, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 4497130.0
Subtract 0 from 5 to get 5.
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:
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: 4497130.4
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.

Let's proceed to step 10:
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: 4497130.41
The remainder is 8 after subtracting 12 from 20.
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:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 4497130.416
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.

Going ahead to step 12:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 4497130.4166
Subtracting 72 from 80 leaves us 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 4497130.4166 with a balance of 8e-05.
