We're dividing 718203 by 12 
Let's see how many times 12 fits into 718203.

Let's proceed to step 1:
When dividing 7 by 12, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 12

On to step 2:
12 goes into 71 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 60 from 71 to get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 12

Advancing to step 3:
If we divide 118 by 12, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
The remainder is 10 after subtracting 108 from 118.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Going ahead to step 4:
102 divided by 12 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 598.0
The remainder is 6 after subtracting 96 from 102.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Moving on to step 5:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5985.0
If we take 60 away from 60, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 12

Step 6:
When dividing 3 by 12, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 59850.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 59850.2
If we take 24 away from 30, 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 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 59850.25
Subtract 60 from 60 to 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.

On to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 59850.25
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.

Moving on to step 10:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 59850.25
Subtract 0 from 0 to 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.

The final result is 59850.25 with a remainder of 0.0.
