We divide 771573 by 9
We're looking to find how many times 9 goes into 771573.

On to step 1:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 9

Advancing to step 2:
The number 9 fits into 77 8 times, leaving a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 72 from 77 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 9

Going ahead to step 3:
9 can be fit into 51 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 85.0
The remainder is 6 after subtracting 45 from 51.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 9

Moving on to step 4:
9 can be fit into 65 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 857.0
If we subtract 63 from 65, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 9

Going ahead to step 5:
If we divide 27 by 9, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 8573.0
Deduct 27 from 27 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

Let's proceed to step 6:
9 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 85730.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
9 goes into 30 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 85730.3
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
When dividing 30 by 9, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 85730.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 85730.33 and a remainder of 0.003.
