646311 ÷ 76 
Let's see how many times 76 fits into 646311.

Moving on to step 1:
When dividing 6 by 76, we get 0 with 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 76

Advancing to step 2:
76 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 76

Moving on to step 3:
The number 76 fits into 646 8 times, leaving a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 608 away from 646, we end up with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 76

Going ahead to step 4:
76 can be fit into 383 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 380 from 383 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 76

On to step 5:
31 divided by 76 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 850.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 76

Going ahead to step 6:
76 can be fit into 311 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 8504.0
The remainder is 7 after subtracting 304 from 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
76 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 8504.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
If we divide 700 by 76, we get 9 and a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 8504.09
If we take 684 away from 700, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
76 can be fit into 160 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8504.092
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 76 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 8504.0921
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 76 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8504.0921
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
The number 76 fits into 400 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 8504.092105
Deduct 380 from 400 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
76 goes into 200 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 8504.0921052
If we subtract 152 from 200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 76, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 8504.09210526
Deduct 456 from 480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 8504.09210526, with a leftover of 2.4e-08.
