646323 ÷ 76 
Let's see how many times 76 fits into 646323.

Moving on to step 1:
If we divide 6 by 76, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 76

Let's proceed to step 2:
The number 76 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 76

On to step 3:
76 can be fit into 646 8 times, resulting in a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 608 from 646 and we're left with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 76

Going ahead to step 4:
If we divide 383 by 76, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 85.0
The remainder is 3 after subtracting 380 from 383.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 76

On to step 5:
If we divide 32 by 76, we get 0 and a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 850.0
Subtract 0 from 32 to get 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 76

Advancing to step 6:
When dividing 323 by 76, we get 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 8504.0
If we subtract 304 from 323, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 76 fits into 190 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 8504.2
Subtract 152 from 190 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.

On to step 8:
76 can be fit into 380 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8504.25
Subtracting 380 from 380 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 76, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8504.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 76 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8504.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8504.25 and a remainder of 0.0.
