We divide 648891 by 42
We're looking to find how many times 42 goes into 648891.

On to step 1:
42 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 42

Let's proceed to step 2:
42 can be fit into 64 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 64, we end up with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 42

Advancing to step 3:
42 can be fit into 228 5 times, resulting in a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 210 from 228 leaves us with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 42

Going ahead to step 4:
The number 42 fits into 188 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we take 168 away from 188, we end up with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 42

Let's proceed to step 5:
If we divide 209 by 42, we get 4 and a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 1544.0
Deduct 168 from 209 and we're left with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 42

Moving on to step 6:
When dividing 411 by 42, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 15449.0
Subtracting 378 from 411 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
The number 42 fits into 330 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 15449.7
Deduct 294 from 330 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.

Advancing to step 8:
If we divide 360 by 42, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 15449.78
Subtracting 336 from 360 leaves us 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.

Moving on to step 9:
42 goes into 240 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 15449.785
Subtract 210 from 240 to 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.

Going ahead to step 10:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 15449.7857
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.

Moving on to 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: 15449.78571
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.

Let's proceed to step 12:
180 divided by 42 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15449.785714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 15449.7857142
If we take 84 away from 120, we end up 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:
42 goes into 360 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 15449.78571428
Subtracting 336 from 360 leaves us 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.

Our division results in 15449.78571428 with a remaining 2.4e-08.
