725315 ÷ 42 
Let's see how many times 42 fits into 725315.

Let's proceed to step 1:
7 divided by 42 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 42

Moving on to step 2:
42 goes into 72 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 72, we get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 42

Step 3:
When dividing 305 by 42, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 294 from 305 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 42

Going ahead to step 4:
When dividing 113 by 42, we get 2 with a remainder of 29.
The next digit of our result is 2. 
Result so far: 172.0
If we take 84 away from 113, we end up with 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 42

Going ahead to step 5:
42 goes into 291 6 times with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 1726.0
If we subtract 252 from 291, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 42

Moving on to step 6:
The number 42 fits into 395 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 17269.0
If we take 378 away from 395, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
42 can be fit into 170 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 17269.4
Subtracting 168 from 170 leaves us with 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 8:
When dividing 20 by 42, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17269.4
If we take 0 away from 20, we end up 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 9:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 17269.404
If we subtract 168 from 200, we 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.

Advancing to step 10:
If we divide 320 by 42, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 17269.4047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 17269.40476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
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: 17269.404761
Subtract 42 from 80 to 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.

Moving on to step 13:
When dividing 380 by 42, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 17269.4047619
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.

On to step 14:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17269.4047619
Deduct 0 from 20 and we're left 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.

After the division, we end up with 17269.4047619 and a remainder of 2e-08.
