We divide 777825 by 51
Let's see how many times 51 fits into 777825.

Going ahead to step 1:
7 divided by 51 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 51

Moving on to step 2:
When dividing 77 by 51, we get 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 77 to get 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 51

Step 3:
51 goes into 267 5 times with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 255 away from 267, we end up with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 51

Step 4:
128 divided by 51 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we take 102 away from 128, we end up with 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 51

Step 5:
51 goes into 262 5 times with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 1525.0
If we subtract 255 from 262, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 51

On to step 6:
The number 51 fits into 75 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 15251.0
If we take 51 away from 75, we end up 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.

On to step 7:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 15251.4
Deduct 204 from 240 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
51 goes into 360 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 15251.47
Deduct 357 from 360 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.

Let's proceed to step 9:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 15251.47
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 51, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 15251.4705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 15251.47058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 15251.470588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 15251.470588 with a remainder of 1.2e-06.
