523548 ÷ 42 
Our goal is to divide 523548 by 42.

Going ahead to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 42

On to step 2:
52 divided by 42 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 52 leaves us with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 42

Going ahead to step 3:
42 can be fit into 103 2 times, resulting in a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 84 from 103, we get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 42

Advancing to step 4:
When dividing 195 by 42, we get 4 with a remainder of 27.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 168 from 195 leaves us with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 42

Step 5:
42 goes into 274 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 1246.0
If we subtract 252 from 274, we get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 42

Advancing to step 6:
228 divided by 42 is 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 12465.0
If we subtract 210 from 228, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 12465.4
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.

Advancing to step 8:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 12465.42
If we subtract 84 from 120, we 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:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12465.428
Deduct 336 from 360 and we're left 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.

Step 10:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 12465.4285
Deduct 210 from 240 and we're left 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.

Going ahead to step 11:
42 goes into 300 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 12465.42857
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.

Moving on to step 12:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 12465.428571
Subtracting 42 from 60 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.

Going ahead to step 13:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 12465.4285714
If we take 168 away from 180, we end up 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.

Going ahead to step 14:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 12465.42857142
Subtracting 84 from 120 leaves us 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.

Our division results in 12465.42857142 with a remaining 3.6e-08.
