We look at the division of 43674555 by 12 
We want to divide 43674555 by 12.

On to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

Advancing to step 2:
43 divided by 12 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 36 from 43 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 12

Going ahead to step 3:
If we divide 76 by 12, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 72 from 76 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 12

Let's proceed to step 4:
If we divide 47 by 12, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 363.0
If we take 36 away from 47, we end up with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 12

Moving on to step 5:
12 goes into 114 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 3639.0
If we subtract 108 from 114, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 12

Step 6:
65 divided by 12 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 36395.0
The remainder is 5 after subtracting 60 from 65.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 12

On to step 7:
If we divide 55 by 12, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 363954.0
Subtract 48 from 55 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 12

Moving on to step 8:
12 can be fit into 75 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 3639546.0
If we subtract 72 from 75, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 3639546.2
Deduct 24 from 30 and we're left 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.

On to step 10:
If we divide 60 by 12, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 3639546.25
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.

Step 11:
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: 3639546.25
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.

Going ahead to step 12:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3639546.25
The remainder is 0 after subtracting 0 from 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 3639546.25 with a remaining 0.0.
