We look at the division of 649791 by 42 
Our goal is to divide 649791 by 42.

On to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 42

Going ahead to step 2:
The number 42 fits into 64 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 42 from 64 leaves us with 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 42

On to step 3:
229 divided by 42 is 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 210 away from 229, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 42

Advancing to step 4:
42 can be fit into 197 4 times, resulting in a remainder of 29.
The next digit of our result is 4. 
Result so far: 154.0
Subtract 168 from 197 to get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 42

On to step 5:
299 divided by 42 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 1547.0
If we take 294 away from 299, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 42

Advancing to step 6:
42 goes into 51 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 15471.0
The remainder is 9 after subtracting 42 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 42 fits into 90 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 15471.2
Deduct 84 from 90 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 8:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 15471.21
If we subtract 42 from 60, 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 9:
If we divide 180 by 42, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 15471.214
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.

Moving on to step 10:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 15471.2142
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.

Advancing to step 11:
42 goes into 360 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 15471.21428
If we take 336 away from 360, we end up 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 12:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15471.214285
If we take 210 away from 240, we end up 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.

Going ahead to step 13:
300 divided by 42 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 15471.2142857
If we subtract 294 from 300, we 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.

Let's proceed to step 14:
42 goes into 60 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 15471.21428571
If we take 42 away from 60, we end up 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.

After the division, we end up with 15471.21428571 and a remainder of 1.8e-08.
