649601 ÷ 42 
We're looking to find how many times 42 goes into 649601.

Step 1:
42 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 42

Going ahead to step 2:
When dividing 64 by 42, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 22 after subtracting 42 from 64.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 42

Step 3:
The number 42 fits into 229 5 times, leaving a remainder of 19.
The next digit of our result is 5. 
Result so far: 15.0
If we take 210 away from 229, we end up with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 42

Let's proceed to step 4:
When dividing 196 by 42, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtract 168 from 196 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 42

Going ahead to step 5:
The number 42 fits into 280 6 times, leaving a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1546.0
If we subtract 252 from 280, we get 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 42

Going ahead to step 6:
If we divide 281 by 42, we get 6 and a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 15466.0
Subtracting 252 from 281 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
290 divided by 42 is 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 15466.6
If we subtract 252 from 290, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 15466.69
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 15466.69
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 15466.6904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 42, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 15466.69047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
If we divide 260 by 42, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 15466.690476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
When dividing 80 by 42, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 15466.6904761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 15466.69047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 15466.69047619 with a remainder of 2e-09.
