We divide 649542 by 42
Our goal is to divide 649542 by 42.

On to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 42

Step 2:
If we divide 64 by 42, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 64 and we're left with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 42

Let's proceed to step 3:
If we divide 229 by 42, we get 5 and a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 210 from 229 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 42

On to step 4:
The number 42 fits into 195 4 times, leaving a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtract 168 from 195 to get 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 42

Step 5:
The number 42 fits into 274 6 times, leaving a remainder of 22.
The next digit of our result is 6. 
Result so far: 1546.0
The remainder is 22 after subtracting 252 from 274.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 42

Step 6:
222 divided by 42 is 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 15465.0
Deduct 210 from 222 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.

Step 7:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 15465.2
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
If we divide 360 by 42, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 15465.28
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
42 goes into 240 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15465.285
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.

Advancing to step 10:
When dividing 300 by 42, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 15465.2857
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.

Step 11:
60 divided by 42 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 15465.28571
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.

Moving on to step 12:
42 goes into 180 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15465.285714
Subtract 168 from 180 to 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.

On to step 13:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 15465.2857142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
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: 15465.28571428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 15465.28571428 and a remainder of 2.4e-08.
