72124493 divided by 342 
Our goal is to divide 72124493 by 342.

Let's proceed to step 1:
If we divide 7 by 342, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 342

Going ahead to step 2:
72 divided by 342 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 342

Step 3:
721 divided by 342 is 2 with a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 684 from 721 and we're left with 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 342

Moving on to step 4:
The number 342 fits into 372 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 342 from 372 and we're left with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 342

Let's proceed to step 5:
The number 342 fits into 304 0 times, leaving a remainder of 304.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Deduct 0 from 304 and we're left with 304.
Bring next digit (4) of the dividend behind the 304 and repeat the process: 3044 / 342

Step 6:
The number 342 fits into 3044 8 times, leaving a remainder of 308.
The number 8 becomes the next digit in our result. 
Result so far: 2108.0
The remainder is 308 after subtracting 2736 from 3044.
Include the next digit (9) from the dividend after 308, then repeat: 3089 / 342

Step 7:
When dividing 3089 by 342, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 21089.0
Subtracting 3078 from 3089 leaves us with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 342

Step 8:
The number 342 fits into 113 0 times, leaving a remainder of 113.
The next digit of our result is 0. 
Result so far: 210890.0
The remainder is 113 after subtracting 0 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 9:
342 goes into 1130 3 times with a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 210890.3
Deduct 1026 from 1130 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 10:
342 goes into 1040 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 210890.33
Subtracting 1026 from 1040 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 210890.33 with a remaining 0.014.
