2687670 ÷ 863 
The aim is to understand the frequency of 863 in 2687670.

Advancing to step 1:
The number 863 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 863

Moving on to step 2:
26 divided by 863 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 863

Moving on to step 3:
268 divided by 863 is 0 with a remainder of 268.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 268, we end up with 268.
Fetch the next digit (7) from the dividend, attach it to 268 and continue: 2687 / 863

Let's proceed to step 4:
863 can be fit into 2687 3 times, resulting in a remainder of 98.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2589 from 2687 and we're left with 98.
Append the next digit (6) from the dividend to 98 and continue with: 986 / 863

Moving on to step 5:
863 can be fit into 986 1 times, resulting in a remainder of 123.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 863 from 986 and we're left with 123.
Append the next digit (7) from the dividend to 123 and continue with: 1237 / 863

Advancing to step 6:
863 can be fit into 1237 1 times, resulting in a remainder of 374.
The next digit of our result is 1. 
Result so far: 311.0
Subtract 863 from 1237 to get 374.
Take the next digit (0) from the dividend and append it to 374, then repeat: 3740 / 863

Advancing to step 7:
If we divide 3740 by 863, we get 4 and a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 3114.0
Subtract 3452 from 3740 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 8:
2880 divided by 863 is 3 with a remainder of 291.
Write down 3 as next digit of the result. 
Result so far: 3114.3
Deduct 2589 from 2880 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 9:
863 can be fit into 2910 3 times, resulting in a remainder of 321.
Write down 3 as next digit of the result. 
Result so far: 3114.33
Subtracting 2589 from 2910 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

The quotient of the division is 3114.33, and the remainder is 0.321.
