We divide 13664315 by 781
We're looking to find how many times 781 goes into 13664315.

Moving on to step 1:
781 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 781

On to step 2:
If we divide 13 by 781, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 781

Going ahead to step 3:
781 goes into 136 0 times with a remainder of 136.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 136, we end up with 136.
Fetch the next digit (6) from the dividend, attach it to 136 and continue: 1366 / 781

Let's proceed to step 4:
1366 divided by 781 is 1 with a remainder of 585.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 585 after subtracting 781 from 1366.
Grab the next digit (4) from the dividend, add it to 585, then carry on: 5854 / 781

On to step 5:
If we divide 5854 by 781, we get 7 and a remainder of 387.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 5467 from 5854 to get 387.
Fetch the next digit (3) from the dividend, attach it to 387 and continue: 3873 / 781

Advancing to step 6:
When dividing 3873 by 781, we get 4 with a remainder of 749.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
Deduct 3124 from 3873 and we're left with 749.
Take the next digit (1) from the dividend and append it to 749, then repeat: 7491 / 781

Let's proceed to step 7:
781 goes into 7491 9 times with a remainder of 462.
Put 9 as the next digit of the answer. 
Result so far: 1749.0
Deduct 7029 from 7491 and we're left with 462.
Grab the next digit (5) from the dividend, add it to 462, then carry on: 4625 / 781

On to step 8:
781 goes into 4625 5 times with a remainder of 720.
Write down 5 as next digit of the result. 
Result so far: 17495.0
If we subtract 3905 from 4625, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 9:
7200 divided by 781 is 9 with a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 17495.9
Subtracting 7029 from 7200 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 10:
1710 divided by 781 is 2 with a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 17495.92
If we subtract 1562 from 1710, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
If we divide 1480 by 781, we get 1 and a remainder of 699.
Record the quotient 1 as the next digit in the result. 
Result so far: 17495.921
The remainder is 699 after subtracting 781 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Moving on to step 12:
781 can be fit into 6990 8 times, resulting in a remainder of 742.
The number 8 becomes the next digit in our result. 
Result so far: 17495.9218
Subtract 6248 from 6990 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 13:
The number 781 fits into 7420 9 times, leaving a remainder of 391.
Use 9 as the next digit of our solution. 
Result so far: 17495.92189
If we subtract 7029 from 7420, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 14:
If we divide 3910 by 781, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 17495.921895
Subtracting 3905 from 3910 leaves us with 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 15:
The number 781 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 17495.921895
Deduct 0 from 50 and we're left 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.

On to step 16:
When dividing 500 by 781, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 17495.921895
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 17495.921895 with a remainder of 5e-07.
