We're dividing 179748 by 42 
We're looking to find how many times 42 goes into 179748.

On to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 42

On to step 2:
17 divided by 42 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 42

Let's proceed to step 3:
42 can be fit into 179 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
If we take 168 away from 179, we end up with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 42

Going ahead to step 4:
The number 42 fits into 117 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 84 from 117, we get 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 42

On to step 5:
When dividing 334 by 42, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
If we take 294 away from 334, we end up with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 42

Advancing to step 6:
408 divided by 42 is 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 4279.0
If we take 378 away from 408, we end up 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.

On to step 7:
42 can be fit into 300 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 4279.7
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
42 goes into 60 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 4279.71
If we take 42 away from 60, we end up 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 9:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4279.714
Subtract 168 from 180 to get 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 10:
When dividing 120 by 42, we get 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 4279.7142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 4279.71428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
42 goes into 240 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4279.714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 4279.7142857
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.

On to step 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4279.71428571
If we take 42 away from 60, we end up 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.

After the division, we end up with 4279.71428571 and a remainder of 1.8e-08.
