Let's divide 18340117 by 781
The aim is to understand the frequency of 781 in 18340117.

On to step 1:
1 divided by 781 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 781

Step 2:
The number 781 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 781

Moving on to step 3:
If we divide 183 by 781, we get 0 and a remainder of 183.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 183 leaves us with 183.
Bring next digit (4) of the dividend behind the 183 and repeat the process: 1834 / 781

Moving on to step 4:
781 can be fit into 1834 2 times, resulting in a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1562 from 1834, we get 272.
Bring next digit (0) of the dividend behind the 272 and repeat the process: 2720 / 781

On to step 5:
781 can be fit into 2720 3 times, resulting in a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 2343 from 2720 leaves us with 377.
Bring next digit (1) of the dividend behind the 377 and repeat the process: 3771 / 781

Advancing to step 6:
781 can be fit into 3771 4 times, resulting in a remainder of 647.
Use 4 as the next digit of our solution. 
Result so far: 234.0
The remainder is 647 after subtracting 3124 from 3771.
Bring next digit (1) of the dividend behind the 647 and repeat the process: 6471 / 781

Going ahead to step 7:
781 can be fit into 6471 8 times, resulting in a remainder of 223.
The next digit of our result is 8. 
Result so far: 2348.0
Subtract 6248 from 6471 to get 223.
Append the next digit (7) from the dividend to 223 and continue with: 2237 / 781

Moving on to step 8:
The number 781 fits into 2237 2 times, leaving a remainder of 675.
The number 2 becomes the next digit in our result. 
Result so far: 23482.0
Subtracting 1562 from 2237 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 9:
When dividing 6750 by 781, we get 8 with a remainder of 502.
Use 8 as the next digit of our solution. 
Result so far: 23482.8
Subtracting 6248 from 6750 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 10:
If we divide 5020 by 781, we get 6 and a remainder of 334.
The number 6 becomes the next digit in our result. 
Result so far: 23482.86
Subtracting 4686 from 5020 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 11:
781 can be fit into 3340 4 times, resulting in a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 23482.864
The remainder is 216 after subtracting 3124 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
The number 781 fits into 2160 2 times, leaving a remainder of 598.
Record the quotient 2 as the next digit in the result. 
Result so far: 23482.8642
If we take 1562 away from 2160, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 13:
5980 divided by 781 is 7 with a remainder of 513.
Use 7 as the next digit of our solution. 
Result so far: 23482.86427
The remainder is 513 after subtracting 5467 from 5980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

On to step 14:
781 goes into 5130 6 times with a remainder of 444.
The number 6 becomes the next digit in our result. 
Result so far: 23482.864276
Subtracting 4686 from 5130 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 15:
When dividing 4440 by 781, we get 5 with a remainder of 535.
Put 5 as the next digit of the answer. 
Result so far: 23482.8642765
Subtracting 3905 from 4440 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 16:
5350 divided by 781 is 6 with a remainder of 664.
Put 6 as the next digit of the answer. 
Result so far: 23482.86427656
Subtracting 4686 from 5350 leaves us with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

The final result is 23482.86427656 with a remainder of 6.64e-07.
