We're dividing 190812 by 42 
Let's see how many times 42 fits into 190812.

Let's proceed to step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 42

Going ahead to step 2:
The number 42 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 42

On to step 3:
42 goes into 190 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 168 from 190 to get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 42

Going ahead to step 4:
The number 42 fits into 228 5 times, leaving a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 210 away from 228, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 42

Advancing to step 5:
181 divided by 42 is 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
The remainder is 13 after subtracting 168 from 181.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 42

Advancing to step 6:
The number 42 fits into 132 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 4543.0
Subtracting 126 from 132 leaves us 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.

Advancing to step 7:
If we divide 60 by 42, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 4543.1
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 4543.14
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 4543.142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 4543.1428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
42 goes into 240 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4543.14285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 4543.142857
Subtract 294 from 300 to get 6.
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 13:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4543.1428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4543.14285714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 4543.14285714 with a remainder of 1.2e-08.
