We divide 363687 by 42
We want to figure out the number of times 363687 can be divided by 42.

Advancing to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 42

Moving on to step 2:
The number 42 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 42

Going ahead to step 3:
42 goes into 363 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 336 from 363 and we're left with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 42

On to step 4:
42 goes into 276 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 252 from 276 and we're left with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 42

Let's proceed to step 5:
If we divide 248 by 42, we get 5 and a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 865.0
The remainder is 38 after subtracting 210 from 248.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 42

Advancing to step 6:
42 goes into 387 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 8659.0
The remainder is 9 after subtracting 378 from 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 42, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 8659.2
Subtracting 84 from 90 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.

Let's proceed to step 8:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 8659.21
Subtract 42 from 60 to 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 9:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 8659.214
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.

Step 10:
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: 8659.2142
Subtract 84 from 120 to 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 11:
If we divide 360 by 42, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 8659.21428
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 12:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8659.214285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 8659.2142857
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.

On to step 14:
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: 8659.21428571
Subtract 42 from 60 to 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.

After the division, we end up with 8659.21428571 and a remainder of 1.8e-08.
