We're dividing 158624 by 42 
We want to divide 158624 by 42.

Let's proceed to step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 42

Advancing to step 2:
15 divided by 42 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 42

Going ahead to step 3:
158 divided by 42 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 126 from 158 to get 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 42

Moving on to step 4:
The number 42 fits into 326 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 294 from 326, we get 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 42

Let's proceed to step 5:
42 goes into 322 7 times with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 377.0
If we subtract 294 from 322, we get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 42

Going ahead to step 6:
The number 42 fits into 284 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 3776.0
Deduct 252 from 284 and we're left 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 7:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 3776.7
Deduct 294 from 320 and we're left 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.

Going ahead to step 8:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 3776.76
If we take 252 away from 260, we end up 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.

Going ahead to step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 3776.761
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.

Step 10:
42 goes into 380 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3776.7619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3776.7619
Subtract 0 from 20 to 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.

Moving on to step 12:
42 can be fit into 200 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3776.761904
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 13:
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: 3776.7619047
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 14:
42 goes into 260 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 3776.76190476
If we take 252 away from 260, we end up 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.

The final outcome is 3776.76190476, with a leftover of 8e-09.
