We divide 43722334 by 12
We're looking to find how many times 12 goes into 43722334.

On to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 12

Step 2:
12 can be fit into 43 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 36 away from 43, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 12

Advancing to step 3:
12 can be fit into 77 6 times, resulting in a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 72 from 77 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 12

On to step 4:
The number 12 fits into 52 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 364.0
Deduct 48 from 52 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

Let's proceed to step 5:
12 goes into 42 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3643.0
Subtracting 36 from 42 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 12

Going ahead to step 6:
12 can be fit into 63 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 36435.0
If we take 60 away from 63, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Advancing to step 7:
12 goes into 33 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 364352.0
If we take 24 away from 33, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 12

Advancing to step 8:
If we divide 94 by 12, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 3643527.0
If we subtract 84 from 94, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 3643527.8
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3643527.83
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3643527.833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 3643527.833, and the remainder is 0.0004.
