We're dividing 201358 by 12 
We want to figure out the number of times 201358 can be divided by 12.

Step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 12

Going ahead to step 2:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 20, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 12

On to step 3:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 72 away from 81, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 12

Moving on to step 4:
12 goes into 93 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
The remainder is 9 after subtracting 84 from 93.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

Advancing to step 5:
95 divided by 12 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 1677.0
Subtract 84 from 95 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

On to step 6:
12 can be fit into 118 9 times, resulting in a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 16779.0
Subtracting 108 from 118 leaves us with 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 7:
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: 16779.8
Subtract 96 from 100 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.

Advancing to step 8:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 16779.83
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.

Advancing to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 16779.833
If we take 36 away from 40, we end up 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.

The quotient of the division is 16779.833, and the remainder is 0.0004.
