We look at the division of 526263 by 42 
Let's see how many times 42 fits into 526263.

Going ahead to step 1:
5 divided by 42 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 42

Advancing to step 2:
42 can be fit into 52 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 10 after subtracting 42 from 52.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 42

Advancing to step 3:
If we divide 106 by 42, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 22 after subtracting 84 from 106.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 42

Let's proceed to step 4:
42 can be fit into 222 5 times, resulting in a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 125.0
The remainder is 12 after subtracting 210 from 222.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 42

On to step 5:
126 divided by 42 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1253.0
Subtract 126 from 126 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 42

Advancing to step 6:
If we divide 3 by 42, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 12530.0
If we take 0 away from 3, we end up 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.

Going ahead to step 7:
42 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 12530.0
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.

Going ahead to step 8:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 12530.07
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 12530.071
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.

Advancing to step 10:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 12530.0714
Subtract 168 from 180 to 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:
If we divide 120 by 42, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 12530.07142
Deduct 84 from 120 and we're left 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:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12530.071428
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.

Moving on to step 13:
If we divide 240 by 42, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 12530.0714285
Subtract 210 from 240 to 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.

Going ahead to step 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 12530.07142857
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.

Our division results in 12530.07142857 with a remaining 6e-09.
