We divide 721225 by 77
We're looking to find how many times 77 goes into 721225.

Going ahead to step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 77

Let's proceed to step 2:
72 divided by 77 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.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 77

On to step 3:
721 divided by 77 is 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 693 from 721 leaves us with 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 77

Let's proceed to step 4:
The number 77 fits into 282 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 231 from 282 to get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 77

Going ahead to step 5:
If we divide 512 by 77, we get 6 and a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 936.0
The remainder is 50 after subtracting 462 from 512.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 77

Going ahead to step 6:
When dividing 505 by 77, we get 6 with a remainder of 43.
The next digit of our result is 6. 
Result so far: 9366.0
The remainder is 43 after subtracting 462 from 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
When dividing 430 by 77, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 9366.5
Subtract 385 from 430 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
450 divided by 77 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 9366.55
Subtract 385 from 450 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 9366.55, with a leftover of 0.065.
