5246 divided by 42 
Our goal is to divide 5246 by 42.

On to step 1:
The number 42 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 42

Moving on to step 2:
The number 42 fits into 52 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 42 from 52, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 42

On to step 3:
42 can be fit into 104 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 12.0
If we take 84 away from 104, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 42

Moving on to step 4:
42 goes into 206 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we subtract 168 from 206, we 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.

Going ahead to step 5:
42 goes into 380 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 124.9
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 6:
When dividing 20 by 42, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 124.9
Deduct 0 from 20 and we're left 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.

Step 7:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 124.904
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.

Advancing to step 8:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 124.9047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 42, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 124.90476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
80 divided by 42 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 124.904761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
42 goes into 380 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 124.9047619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 124.9047619
If we subtract 0 from 20, we 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.

Our division results in 124.9047619 with a remaining 2e-08.
