We divide 51782970 by 12
Our goal is to divide 51782970 by 12.

Moving on to step 1:
5 divided by 12 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 12

Step 2:
51 divided by 12 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 48 away from 51, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 12

Step 3:
37 divided by 12 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 36 from 37 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

On to step 4:
12 goes into 18 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 431.0
Subtract 12 from 18 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 12

Going ahead to step 5:
If we divide 62 by 12, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 4315.0
Subtracting 60 from 62 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 12

Going ahead to step 6:
When dividing 29 by 12, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 43152.0
Deduct 24 from 29 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 12

Going ahead to step 7:
The number 12 fits into 57 4 times, leaving a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 431524.0
Deduct 48 from 57 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Step 8:
90 divided by 12 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 4315247.0
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4315247.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4315247.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4315247.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4315247.5, with a leftover of 0.0.
