We're dividing 3787869 by 12 
Let's see how many times 12 fits into 3787869.

Moving on to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 12

On to step 2:
12 goes into 37 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 36 from 37.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 12

Going ahead to step 3:
If we divide 18 by 12, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 6 after subtracting 12 from 18.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 12

Let's proceed to step 4:
The number 12 fits into 67 5 times, leaving a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Deduct 60 from 67 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 12

Going ahead to step 5:
If we divide 78 by 12, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3156.0
If we subtract 72 from 78, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 12

Let's proceed to step 6:
When dividing 66 by 12, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 31565.0
Subtracting 60 from 66 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

On to step 7:
12 can be fit into 69 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 315655.0
Subtracting 60 from 69 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 315655.7
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.

Moving on to step 9:
60 divided by 12 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 315655.75
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:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 315655.75
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.

On to step 11:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 315655.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 315655.75 with a remaining 0.0.
