658602 ÷ 12 
We're looking to find how many times 12 goes into 658602.

Moving on to step 1:
6 divided by 12 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 12

Moving on to step 2:
When dividing 65 by 12, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 60 from 65 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 12

Step 3:
12 goes into 58 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 10 after subtracting 48 from 58.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 12

Let's proceed to step 4:
If we divide 106 by 12, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 548.0
If we subtract 96 from 106, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 12

Step 5:
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: 5488.0
If we take 96 away from 100, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 12

Moving on to step 6:
If we divide 42 by 12, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 54883.0
The remainder is 6 after subtracting 36 from 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 12, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 54883.5
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.

Going ahead to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 54883.5
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.

On to step 9:
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: 54883.5
If we take 0 away from 0, we end up 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.

Our division results in 54883.5 with a remaining 0.0.
