We're dividing 6406814 by 766 
Let's see how many times 766 fits into 6406814.

Moving on to step 1:
766 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 766

Step 2:
If we divide 64 by 766, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 766

Step 3:
When dividing 640 by 766, we get 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 640 to get 640.
Grab the next digit (6) from the dividend, add it to 640, then carry on: 6406 / 766

On to step 4:
766 goes into 6406 8 times with a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 278 after subtracting 6128 from 6406.
Fetch the next digit (8) from the dividend, attach it to 278 and continue: 2788 / 766

On to step 5:
When dividing 2788 by 766, we get 3 with a remainder of 490.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtract 2298 from 2788 to get 490.
Fetch the next digit (1) from the dividend, attach it to 490 and continue: 4901 / 766

Moving on to step 6:
When dividing 4901 by 766, we get 6 with a remainder of 305.
Put 6 as the next digit of the answer. 
Result so far: 836.0
Subtracting 4596 from 4901 leaves us with 305.
Grab the next digit (4) from the dividend, add it to 305, then carry on: 3054 / 766

Going ahead to step 7:
766 can be fit into 3054 3 times, resulting in a remainder of 756.
Write down 3 as next digit of the result. 
Result so far: 8363.0
Deduct 2298 from 3054 and we're left with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

On to step 8:
766 can be fit into 7560 9 times, resulting in a remainder of 666.
Put 9 as the next digit of the answer. 
Result so far: 8363.9
Deduct 6894 from 7560 and we're left with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 9:
766 goes into 6660 8 times with a remainder of 532.
Write down 8 as next digit of the result. 
Result so far: 8363.98
If we take 6128 away from 6660, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 10:
When dividing 5320 by 766, we get 6 with a remainder of 724.
Write down 6 as next digit of the result. 
Result so far: 8363.986
The remainder is 724 after subtracting 4596 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Step 11:
766 can be fit into 7240 9 times, resulting in a remainder of 346.
The next digit of our result is 9. 
Result so far: 8363.9869
If we subtract 6894 from 7240, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 12:
766 can be fit into 3460 4 times, resulting in a remainder of 396.
The next digit of our result is 4. 
Result so far: 8363.98694
If we take 3064 away from 3460, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 13:
766 goes into 3960 5 times with a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 8363.986945
Deduct 3830 from 3960 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
The number 766 fits into 1300 1 times, leaving a remainder of 534.
Write down 1 as next digit of the result. 
Result so far: 8363.9869451
Deduct 766 from 1300 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 15:
If we divide 5340 by 766, we get 6 and a remainder of 744.
The next digit of our result is 6. 
Result so far: 8363.98694516
Subtracting 4596 from 5340 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

The final outcome is 8363.98694516, with a leftover of 7.44e-07.
