We divide 6410963 by 781
The aim is to understand the frequency of 781 in 6410963.

On to step 1:
The number 781 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 781

Moving on to step 2:
781 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 781

On to step 3:
If we divide 641 by 781, we get 0 and a remainder of 641.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 641 after subtracting 0 from 641.
Take the next digit (0) from the dividend and append it to 641, then repeat: 6410 / 781

Let's proceed to step 4:
781 can be fit into 6410 8 times, resulting in a remainder of 162.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6248 from 6410 and we're left with 162.
Grab the next digit (9) from the dividend, add it to 162, then carry on: 1629 / 781

Advancing to step 5:
781 can be fit into 1629 2 times, resulting in a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 82.0
Deduct 1562 from 1629 and we're left with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 781

Moving on to step 6:
676 divided by 781 is 0 with a remainder of 676.
Put 0 as the next digit of the answer. 
Result so far: 820.0
Subtract 0 from 676 to get 676.
Append the next digit (3) from the dividend to 676 and continue with: 6763 / 781

On to step 7:
If we divide 6763 by 781, we get 8 and a remainder of 515.
The number 8 becomes the next digit in our result. 
Result so far: 8208.0
The remainder is 515 after subtracting 6248 from 6763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 8:
781 goes into 5150 6 times with a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 8208.6
Subtracting 4686 from 5150 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 9:
781 can be fit into 4640 5 times, resulting in a remainder of 735.
Write down 5 as next digit of the result. 
Result so far: 8208.65
Deduct 3905 from 4640 and we're left with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

On to step 10:
The number 781 fits into 7350 9 times, leaving a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 8208.659
Subtract 7029 from 7350 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 11:
3210 divided by 781 is 4 with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 8208.6594
The remainder is 86 after subtracting 3124 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 12:
When dividing 860 by 781, we get 1 with a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 8208.65941
Deduct 781 from 860 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 13:
790 divided by 781 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 8208.659411
If we take 781 away from 790, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 8208.659411, with a leftover of 9e-07.
