We divide 645111 by 42
Our goal is to divide 645111 by 42.

Going ahead to step 1:
6 divided by 42 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 42

Step 2:
If we divide 64 by 42, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 42 from 64 to get 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 42

On to step 3:
42 goes into 225 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 210 from 225 and we're left with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 42

Step 4:
If we divide 151 by 42, we get 3 and a remainder of 25.
The next digit of our result is 3. 
Result so far: 153.0
Deduct 126 from 151 and we're left with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 42

On to step 5:
When dividing 251 by 42, we get 5 with a remainder of 41.
The next digit of our result is 5. 
Result so far: 1535.0
The remainder is 41 after subtracting 210 from 251.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 42

Step 6:
42 can be fit into 411 9 times, resulting in a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 15359.0
The remainder is 33 after subtracting 378 from 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
The number 42 fits into 330 7 times, leaving a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 15359.7
Subtract 294 from 330 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.

Let's proceed to step 8:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 15359.78
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.

Let's proceed to step 9:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15359.785
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 15359.7857
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:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 15359.78571
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:
When dividing 180 by 42, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 15359.785714
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.

Let's proceed to step 13:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 15359.7857142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 15359.78571428
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.

The final result is 15359.78571428 with a remainder of 2.4e-08.
