531914 ÷ 42 
Our goal is to divide 531914 by 42.

Let's proceed to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 42

On to step 2:
42 goes into 53 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 42 from 53 and we're left with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 42

Let's proceed to step 3:
42 can be fit into 111 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 84 from 111 leaves us with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 42

Advancing to step 4:
42 can be fit into 279 6 times, resulting in a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we subtract 252 from 279, we get 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 42

On to step 5:
If we divide 271 by 42, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
If we subtract 252 from 271, we get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 42

On to step 6:
194 divided by 42 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 12664.0
The remainder is 26 after subtracting 168 from 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 12664.6
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.

Advancing to step 8:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 12664.61
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
42 goes into 380 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 12664.619
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 10:
42 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12664.619
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 11:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 12664.61904
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.

On to step 12:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 12664.619047
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 12664.6190476
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.

Let's proceed to step 14:
80 divided by 42 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 12664.61904761
If we subtract 42 from 80, 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.

The final outcome is 12664.61904761, with a leftover of 3.8e-08.
