72105561 divided by 712 
Let's see how many times 712 fits into 72105561.

Step 1:
When dividing 7 by 712, we get 0 with 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.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 712

Moving on to step 2:
72 divided by 712 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 712

Let's proceed to step 3:
When dividing 721 by 712, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 712 from 721 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 712

Moving on to step 4:
712 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 90 after subtracting 0 from 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 712

On to step 5:
905 divided by 712 is 1 with a remainder of 193.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 193 after subtracting 712 from 905.
Grab the next digit (5) from the dividend, add it to 193, then carry on: 1935 / 712

Moving on to step 6:
712 goes into 1935 2 times with a remainder of 511.
Write down 2 as next digit of the result. 
Result so far: 1012.0
Subtracting 1424 from 1935 leaves us with 511.
Grab the next digit (6) from the dividend, add it to 511, then carry on: 5116 / 712

Step 7:
712 can be fit into 5116 7 times, resulting in a remainder of 132.
Write down 7 as next digit of the result. 
Result so far: 10127.0
Subtracting 4984 from 5116 leaves us with 132.
Grab the next digit (1) from the dividend, add it to 132, then carry on: 1321 / 712

Moving on to step 8:
712 can be fit into 1321 1 times, resulting in a remainder of 609.
The number 1 becomes the next digit in our result. 
Result so far: 101271.0
Deduct 712 from 1321 and we're left with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Let's proceed to step 9:
When dividing 6090 by 712, we get 8 with a remainder of 394.
The next digit of our result is 8. 
Result so far: 101271.8
Subtract 5696 from 6090 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 10:
The number 712 fits into 3940 5 times, leaving a remainder of 380.
The next digit of our result is 5. 
Result so far: 101271.85
Subtract 3560 from 3940 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
3800 divided by 712 is 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 101271.855
The remainder is 240 after subtracting 3560 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 101271.855 with a remainder of 0.024.
