We divide 198286 by 42
Let's see how many times 42 fits into 198286.

Step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 42

Let's proceed to step 2:
When dividing 19 by 42, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 42

Advancing to step 3:
The number 42 fits into 198 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 168 from 198 and we're left with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 42

Moving on to step 4:
If we divide 302 by 42, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 294 from 302, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 42

On to step 5:
42 can be fit into 88 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 472.0
Deduct 84 from 88 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 42

On to step 6:
When dividing 46 by 42, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 4721.0
Subtracting 42 from 46 leaves us 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.

Step 7:
If we divide 40 by 42, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4721.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 4721.09
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4721.095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 42 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4721.0952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
When dividing 160 by 42, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 4721.09523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 4721.095238
Subtracting 336 from 340 leaves us 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.

Step 13:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4721.095238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
42 goes into 400 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 4721.09523809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 4721.09523809 with a remainder of 2.2e-08.
