178574 divided by 42 
Our goal is to divide 178574 by 42.

Step 1:
42 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 42

Moving on to step 2:
42 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 42

Step 3:
The number 42 fits into 178 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 168 from 178 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 42

Moving on to step 4:
The number 42 fits into 105 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 84 from 105 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 42

Step 5:
42 goes into 217 5 times with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.0
If we take 210 away from 217, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

Step 6:
If we divide 74 by 42, we get 1 and a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 4251.0
The remainder is 32 after subtracting 42 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 4251.7
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 8:
42 goes into 260 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4251.76
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 9:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 4251.761
Deduct 42 from 80 and we're left 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.

On to step 10:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 4251.7619
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.

On to step 11:
When dividing 20 by 42, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4251.7619
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.

Moving on to step 12:
When dividing 200 by 42, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4251.761904
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.

Let's proceed to step 13:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 4251.7619047
Subtract 294 from 320 to 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.

On to step 14:
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: 4251.76190476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 4251.76190476, with a leftover of 8e-09.
