We're dividing 42120 by 73 
Our goal is to divide 42120 by 73.

On to step 1:
4 divided by 73 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 73

Let's proceed to step 2:
73 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 73

Going ahead to step 3:
73 can be fit into 421 5 times, resulting in a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 365 from 421, we get 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 73

Going ahead to step 4:
562 divided by 73 is 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 511 from 562, we get 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 73

Going ahead to step 5:
If we divide 510 by 73, we get 6 and a remainder of 72.
The next digit of our result is 6. 
Result so far: 576.0
The remainder is 72 after subtracting 438 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 6:
720 divided by 73 is 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 576.9
Subtract 657 from 720 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
The number 73 fits into 630 8 times, leaving a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 576.98
Subtracting 584 from 630 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
73 goes into 460 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 576.986
Subtract 438 from 460 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 73, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 576.9863
Deduct 219 from 220 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 73 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 576.9863
Deduct 0 from 10 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.

Advancing to step 11:
100 divided by 73 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 576.986301
Subtract 73 from 100 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
73 goes into 270 3 times with a remainder of 51.
The next digit of our result is 3. 
Result so far: 576.9863013
If we take 219 away from 270, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
510 divided by 73 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 576.98630136
If we take 438 away from 510, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 576.98630136 and a remainder of 7.2e-08.
