We're dividing 51459550 by 774 
Let's see how many times 774 fits into 51459550.

On to step 1:
When dividing 5 by 774, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 774

Going ahead to step 2:
When dividing 51 by 774, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 774

Let's proceed to step 3:
514 divided by 774 is 0 with a remainder of 514.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 514 leaves us with 514.
Grab the next digit (5) from the dividend, add it to 514, then carry on: 5145 / 774

On to step 4:
774 goes into 5145 6 times with a remainder of 501.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4644 from 5145 leaves us with 501.
Include the next digit (9) from the dividend after 501, then repeat: 5019 / 774

Let's proceed to step 5:
5019 divided by 774 is 6 with a remainder of 375.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 4644 from 5019 and we're left with 375.
Include the next digit (5) from the dividend after 375, then repeat: 3755 / 774

Advancing to step 6:
The number 774 fits into 3755 4 times, leaving a remainder of 659.
The next digit of our result is 4. 
Result so far: 664.0
Deduct 3096 from 3755 and we're left with 659.
Include the next digit (5) from the dividend after 659, then repeat: 6595 / 774

Advancing to step 7:
When dividing 6595 by 774, we get 8 with a remainder of 403.
Put 8 as the next digit of the answer. 
Result so far: 6648.0
If we subtract 6192 from 6595, we get 403.
Bring next digit (0) of the dividend behind the 403 and repeat the process: 4030 / 774

On to step 8:
774 can be fit into 4030 5 times, resulting in a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 66485.0
If we subtract 3870 from 4030, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
When dividing 1600 by 774, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 66485.2
If we subtract 1548 from 1600, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
774 goes into 520 0 times with a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 66485.2
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 11:
774 goes into 5200 6 times with a remainder of 556.
Use 6 as the next digit of our solution. 
Result so far: 66485.206
If we take 4644 away from 5200, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 12:
5560 divided by 774 is 7 with a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 66485.2067
If we subtract 5418 from 5560, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 13:
1420 divided by 774 is 1 with a remainder of 646.
The next digit of our result is 1. 
Result so far: 66485.20671
The remainder is 646 after subtracting 774 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Let's proceed to step 14:
When dividing 6460 by 774, we get 8 with a remainder of 268.
Use 8 as the next digit of our solution. 
Result so far: 66485.206718
Subtract 6192 from 6460 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 15:
774 can be fit into 2680 3 times, resulting in a remainder of 358.
The next digit of our result is 3. 
Result so far: 66485.2067183
If we subtract 2322 from 2680, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 16:
774 can be fit into 3580 4 times, resulting in a remainder of 484.
Record the quotient 4 as the next digit in the result. 
Result so far: 66485.20671834
The remainder is 484 after subtracting 3096 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

After the division, we end up with 66485.20671834 and a remainder of 4.84e-07.
