We divide 438107 by 12
Let's see how many times 12 fits into 438107.

Step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

Let's proceed to step 2:
When dividing 43 by 12, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 36 from 43, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 12

On to step 3:
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: 36.0
Deduct 72 from 78 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

Advancing to step 4:
The number 12 fits into 61 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 365.0
Subtracting 60 from 61 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Step 5:
If we divide 10 by 12, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3650.0
If we subtract 0 from 10, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 12

Moving on to step 6:
When dividing 107 by 12, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 36508.0
Subtracting 96 from 107 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
12 goes into 110 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 36508.9
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 12 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 36508.91
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 36508.916
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 36508.9166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 36508.9166 and a remainder of 8e-05.
