We're dividing 781325 by 51 
We want to divide 781325 by 51.

On to step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 51

Let's proceed to step 2:
78 divided by 51 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 51 from 78 leaves us with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 51

On to step 3:
51 can be fit into 271 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 255 from 271 to get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 51

Advancing to step 4:
If we divide 163 by 51, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Deduct 153 from 163 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 51

Going ahead to step 5:
51 can be fit into 102 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 1532.0
Subtracting 102 from 102 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 51

Step 6:
The number 51 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 15320.0
Subtract 0 from 5 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 15320.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 15320.09
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 15320.098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
51 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15320.098
If we subtract 0 from 20, we get 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 11:
200 divided by 51 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 15320.09803
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
470 divided by 51 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 15320.098039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 15320.0980392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
51 goes into 80 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 15320.09803921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 15320.09803921, with a leftover of 2.9e-08.
