We divide 199350 by 42
We want to figure out the number of times 199350 can be divided by 42.

On to step 1:
42 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 42

Going ahead to step 2:
When dividing 19 by 42, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 42

Going ahead to step 3:
42 goes into 199 4 times with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 31 after subtracting 168 from 199.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 42

On to step 4:
313 divided by 42 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
The remainder is 19 after subtracting 294 from 313.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 42

Let's proceed to step 5:
The number 42 fits into 195 4 times, leaving a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
The remainder is 27 after subtracting 168 from 195.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 42

Going ahead to step 6:
If we divide 270 by 42, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 4746.0
If we subtract 252 from 270, we get 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 7:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4746.4
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.

Moving on to step 8:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 4746.42
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
360 divided by 42 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 4746.428
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.

Advancing to step 10:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 4746.4285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
If we divide 300 by 42, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 4746.42857
Deduct 294 from 300 and we're left 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.

On to step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 4746.428571
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.

On to step 13:
If we divide 180 by 42, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4746.4285714
If we subtract 168 from 180, we get 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 14:
When dividing 120 by 42, we get 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 4746.42857142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 4746.42857142 and a remainder of 3.6e-08.
