We divide 422173 by 12
Our goal is to divide 422173 by 12.

On to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

Moving on to step 2:
If we divide 42 by 12, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 36 from 42 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 12

Going ahead to step 3:
When dividing 62 by 12, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 60 from 62, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 12

Let's proceed to step 4:
If we divide 21 by 12, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 351.0
Subtract 12 from 21 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 12

On to step 5:
If we divide 97 by 12, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 3518.0
The remainder is 1 after subtracting 96 from 97.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 12

Moving on to step 6:
13 divided by 12 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 35181.0
Subtracting 12 from 13 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 35181.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 35181.08
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 35181.083
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 35181.0833
Subtract 36 from 40 to 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.

Our division results in 35181.0833 with a remaining 4e-05.
