We look at the division of 65840635 by 863 
The aim is to understand the frequency of 863 in 65840635.

Let's proceed to step 1:
863 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 863

Moving on to step 2:
863 can be fit into 65 0 times, resulting in a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 863

Moving on to step 3:
The number 863 fits into 658 0 times, leaving a remainder of 658.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 658 to get 658.
Fetch the next digit (4) from the dividend, attach it to 658 and continue: 6584 / 863

Let's proceed to step 4:
When dividing 6584 by 863, we get 7 with a remainder of 543.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 6041 from 6584 to get 543.
Include the next digit (0) from the dividend after 543, then repeat: 5430 / 863

Going ahead to step 5:
863 goes into 5430 6 times with a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 5178 from 5430 to get 252.
Fetch the next digit (6) from the dividend, attach it to 252 and continue: 2526 / 863

Moving on to step 6:
863 goes into 2526 2 times with a remainder of 800.
The next digit of our result is 2. 
Result so far: 762.0
Subtract 1726 from 2526 to get 800.
Append the next digit (3) from the dividend to 800 and continue with: 8003 / 863

Going ahead to step 7:
8003 divided by 863 is 9 with a remainder of 236.
Put 9 as the next digit of the answer. 
Result so far: 7629.0
If we take 7767 away from 8003, we end up with 236.
Append the next digit (5) from the dividend to 236 and continue with: 2365 / 863

Going ahead to step 8:
The number 863 fits into 2365 2 times, leaving a remainder of 639.
Put 2 as the next digit of the answer. 
Result so far: 76292.0
The remainder is 639 after subtracting 1726 from 2365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Moving on to step 9:
6390 divided by 863 is 7 with a remainder of 349.
Put 7 as the next digit of the answer. 
Result so far: 76292.7
If we take 6041 away from 6390, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 10:
If we divide 3490 by 863, we get 4 and a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 76292.74
If we take 3452 away from 3490, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
When dividing 380 by 863, we get 0 with a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 76292.74
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 12:
When dividing 3800 by 863, we get 4 with a remainder of 348.
Put 4 as the next digit of the answer. 
Result so far: 76292.7404
If we subtract 3452 from 3800, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 13:
If we divide 3480 by 863, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 76292.74044
Deduct 3452 from 3480 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 76292.74044, and the remainder is 2.8e-05.
