We're dividing 344980 by 42 
We're looking to find how many times 42 goes into 344980.

On to step 1:
3 divided by 42 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 42

Let's proceed to step 2:
The number 42 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 42

Let's proceed to step 3:
42 can be fit into 344 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 336 from 344, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 42

Step 4:
89 divided by 42 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 84 from 89, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 42

Step 5:
58 divided by 42 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 821.0
Deduct 42 from 58 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 42

Step 6:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 8213.0
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8213.8
Deduct 336 from 340 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 42, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8213.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 42, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 8213.809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
42 goes into 220 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 8213.8095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 8213.80952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 8213.809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 8213.8095238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
40 divided by 42 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8213.8095238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 8213.8095238 with a remainder of 4e-08.
