We're dividing 301550 by 42 
Let's see how many times 42 fits into 301550.

Going ahead to step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 42

On to step 2:
The number 42 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 42

On to step 3:
When dividing 301 by 42, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 294 from 301 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 42

Moving on to step 4:
The number 42 fits into 75 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 42 from 75 and we're left with 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 42

Going ahead to step 5:
The number 42 fits into 335 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 717.0
The remainder is 41 after subtracting 294 from 335.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 42

Step 6:
410 divided by 42 is 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 7179.0
Deduct 378 from 410 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.

Moving on to step 7:
320 divided by 42 is 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 7179.7
Subtracting 294 from 320 leaves us 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 8:
42 goes into 260 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7179.76
Deduct 252 from 260 and we're left 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.

On 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: 7179.761
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.

Going ahead to step 10:
42 goes into 380 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 7179.7619
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 11:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7179.7619
Subtracting 0 from 20 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.

Moving on to step 12:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7179.761904
Subtract 168 from 200 to 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.

Moving on to step 13:
If we divide 320 by 42, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 7179.7619047
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.

Advancing to step 14:
If we divide 260 by 42, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7179.76190476
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 7179.76190476, with a leftover of 8e-09.
