Let's divide 456585 by 42
We want to divide 456585 by 42.

On to step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 42

Let's proceed to step 2:
42 goes into 45 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 45 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 42

Advancing to step 3:
42 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 42

Advancing to step 4:
If we divide 365 by 42, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Deduct 336 from 365 and we're left with 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 42

Going ahead to step 5:
42 can be fit into 298 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1087.0
If we take 294 away from 298, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 42

Advancing to step 6:
When dividing 45 by 42, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 10871.0
Deduct 42 from 45 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 42, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10871.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 42, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 10871.07
The remainder is 6 after subtracting 294 from 300.
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 9:
42 goes into 60 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 10871.071
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.

Step 10:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 10871.0714
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 11:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 10871.07142
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.

On to step 12:
42 goes into 360 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 10871.071428
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 13:
The number 42 fits into 240 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10871.0714285
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.

On to step 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 10871.07142857
Subtracting 294 from 300 leaves us 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.

The final result is 10871.07142857 with a remainder of 6e-09.
