Let's divide 66513 by 42
Let's see how many times 42 fits into 66513.

On to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 42

Step 2:
66 divided by 42 is 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 66 leaves us with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 42

On to step 3:
245 divided by 42 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 210 from 245 to get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 42

On to step 4:
If we divide 351 by 42, we get 8 and a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtracting 336 from 351 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 42

Let's proceed to step 5:
42 can be fit into 153 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 1583.0
If we subtract 126 from 153, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 6:
42 goes into 270 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 1583.6
Subtracting 252 from 270 leaves us 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.

Let's proceed to step 7:
42 goes into 180 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 1583.64
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 8:
42 goes into 120 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 1583.642
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.

Step 9:
360 divided by 42 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1583.6428
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.

Advancing to step 10:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1583.64285
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.

Let's proceed to step 11:
300 divided by 42 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 1583.642857
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 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1583.6428571
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.

On to step 13:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 1583.64285714
Subtracting 168 from 180 leaves us 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.

Our division results in 1583.64285714 with a remaining 1.2e-08.
