1259147 ÷ 781 
We want to divide 1259147 by 781.

On to step 1:
The number 781 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 781

Step 2:
781 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 781

Step 3:
When dividing 125 by 781, we get 0 with a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 781

Let's proceed to step 4:
If we divide 1259 by 781, we get 1 and a remainder of 478.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 781 from 1259 to get 478.
Take the next digit (1) from the dividend and append it to 478, then repeat: 4781 / 781

Advancing to step 5:
4781 divided by 781 is 6 with a remainder of 95.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 4686 from 4781 leaves us with 95.
Take the next digit (4) from the dividend and append it to 95, then repeat: 954 / 781

On to step 6:
The number 781 fits into 954 1 times, leaving a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Subtracting 781 from 954 leaves us with 173.
Fetch the next digit (7) from the dividend, attach it to 173 and continue: 1737 / 781

Advancing to step 7:
781 can be fit into 1737 2 times, resulting in a remainder of 175.
The next digit of our result is 2. 
Result so far: 1612.0
If we take 1562 away from 1737, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 8:
The number 781 fits into 1750 2 times, leaving a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 1612.2
Subtract 1562 from 1750 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 9:
781 can be fit into 1880 2 times, resulting in a remainder of 318.
The next digit of our result is 2. 
Result so far: 1612.22
If we take 1562 away from 1880, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Our division results in 1612.22 with a remaining 0.318.
