We're dividing 561434 by 72 
Let's see how many times 72 fits into 561434.

Step 1:
The number 72 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 72

Step 2:
72 goes into 56 0 times with a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 72

Moving on to step 3:
72 can be fit into 561 7 times, resulting in a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 504 from 561 to get 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 72

Step 4:
574 divided by 72 is 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtract 504 from 574 to get 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 72

Going ahead to step 5:
72 can be fit into 703 9 times, resulting in a remainder of 55.
The next digit of our result is 9. 
Result so far: 779.0
If we take 648 away from 703, we end up with 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 72

Advancing to step 6:
72 can be fit into 554 7 times, resulting in a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 7797.0
Deduct 504 from 554 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
72 can be fit into 500 6 times, resulting in a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 7797.6
Deduct 432 from 500 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
680 divided by 72 is 9 with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 7797.69
Subtract 648 from 680 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.

Going ahead to step 9:
72 goes into 320 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 7797.694
If we take 288 away from 320, we end up 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.

Step 10:
The number 72 fits into 320 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 7797.6944
Subtract 288 from 320 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.

After the division, we end up with 7797.6944 and a remainder of 0.00032.
