We're dividing 180494 by 42 
We want to divide 180494 by 42.

Moving on to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 42

Moving on to step 2:
42 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 42

On to step 3:
42 goes into 180 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 168 away from 180, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 42

Advancing to step 4:
If we divide 124 by 42, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 84 from 124, we get 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 42

Step 5:
The number 42 fits into 409 9 times, leaving a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 429.0
If we subtract 378 from 409, we get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 42

Moving on to step 6:
314 divided by 42 is 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 4297.0
Subtracting 294 from 314 leaves us 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.

On to step 7:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 4297.4
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 8:
320 divided by 42 is 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 4297.47
If we take 294 away from 320, we end up 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.

Step 9:
260 divided by 42 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4297.476
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.

Moving on to step 10:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 4297.4761
If we take 42 away from 80, we end up 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.

Moving on to step 11:
380 divided by 42 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 4297.47619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
42 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4297.47619
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.

Going ahead to step 13:
When dividing 200 by 42, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 4297.4761904
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 14:
320 divided by 42 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 4297.47619047
If we take 294 away from 320, we end up 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.

The final result is 4297.47619047 with a remainder of 2.6e-08.
