508916 ÷ 42 
We want to divide 508916 by 42.

Moving on to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 42

Advancing to step 2:
When dividing 50 by 42, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 50, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 42

Let's proceed to step 3:
42 goes into 88 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 4 after subtracting 84 from 88.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 42

On to step 4:
The number 42 fits into 49 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Deduct 42 from 49 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 42

Moving on to step 5:
42 goes into 71 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1211.0
Deduct 42 from 71 and we're left with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 42

Going ahead to step 6:
42 can be fit into 296 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 12117.0
The remainder is 2 after subtracting 294 from 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 42, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12117.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 12117.04
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.

Going ahead to step 9:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 12117.047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 12117.0476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 12117.04761
Subtract 42 from 80 to 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.

Step 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 12117.047619
If we subtract 378 from 380, we 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.

Going ahead to step 13:
42 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 12117.047619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 12117.04761904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 12117.04761904 with a remaining 3.2e-08.
