66450624 divided by 781 
The aim is to understand the frequency of 781 in 66450624.

Advancing to step 1:
The number 781 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 781

Advancing to step 2:
781 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 781

Going ahead to step 3:
781 can be fit into 664 0 times, resulting in a remainder of 664.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 664, we get 664.
Append the next digit (5) from the dividend to 664 and continue with: 6645 / 781

Going ahead to step 4:
781 goes into 6645 8 times with a remainder of 397.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 6248 from 6645, we get 397.
Include the next digit (0) from the dividend after 397, then repeat: 3970 / 781

Step 5:
781 can be fit into 3970 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we take 3905 away from 3970, we end up with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 781

Advancing to step 6:
The number 781 fits into 656 0 times, leaving a remainder of 656.
Use 0 as the next digit of our solution. 
Result so far: 850.0
Subtracting 0 from 656 leaves us with 656.
Grab the next digit (2) from the dividend, add it to 656, then carry on: 6562 / 781

Let's proceed to step 7:
781 can be fit into 6562 8 times, resulting in a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 8508.0
If we subtract 6248 from 6562, we get 314.
Bring next digit (4) of the dividend behind the 314 and repeat the process: 3144 / 781

On to step 8:
781 can be fit into 3144 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 85084.0
If we subtract 3124 from 3144, 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.

Advancing to step 9:
781 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 85084.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
If we divide 2000 by 781, we get 2 and a remainder of 438.
The number 2 becomes the next digit in our result. 
Result so far: 85084.02
If we take 1562 away from 2000, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 11:
If we divide 4380 by 781, we get 5 and a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 85084.025
The remainder is 475 after subtracting 3905 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 12:
When dividing 4750 by 781, we get 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 85084.0256
If we take 4686 away from 4750, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
If we divide 640 by 781, we get 0 and a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 85084.0256
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 14:
When dividing 6400 by 781, we get 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 85084.025608
Subtract 6248 from 6400 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 15:
781 goes into 1520 1 times with a remainder of 739.
Record the quotient 1 as the next digit in the result. 
Result so far: 85084.0256081
If we subtract 781 from 1520, we get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Step 16:
781 can be fit into 7390 9 times, resulting in a remainder of 361.
Write down 9 as next digit of the result. 
Result so far: 85084.02560819
Deduct 7029 from 7390 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

The quotient of the division is 85084.02560819, and the remainder is 3.61e-07.
