17277111 divided by 861 
The aim is to understand the frequency of 861 in 17277111.

Let's proceed to step 1:
861 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 861

Going ahead to step 2:
When dividing 17 by 861, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 861

Let's proceed to step 3:
172 divided by 861 is 0 with a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 172 and we're left with 172.
Take the next digit (7) from the dividend and append it to 172, then repeat: 1727 / 861

Moving on to step 4:
861 can be fit into 1727 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1722 from 1727 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 861

Moving on to step 5:
The number 861 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 861

Going ahead to step 6:
571 divided by 861 is 0 with a remainder of 571.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
If we take 0 away from 571, we end up with 571.
Bring next digit (1) of the dividend behind the 571 and repeat the process: 5711 / 861

Moving on to step 7:
861 can be fit into 5711 6 times, resulting in a remainder of 545.
The next digit of our result is 6. 
Result so far: 2006.0
If we take 5166 away from 5711, we end up with 545.
Include the next digit (1) from the dividend after 545, then repeat: 5451 / 861

Going ahead to step 8:
When dividing 5451 by 861, we get 6 with a remainder of 285.
Use 6 as the next digit of our solution. 
Result so far: 20066.0
Subtract 5166 from 5451 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 9:
861 goes into 2850 3 times with a remainder of 267.
Use 3 as the next digit of our solution. 
Result so far: 20066.3
If we subtract 2583 from 2850, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 10:
861 can be fit into 2670 3 times, resulting in a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 20066.33
Subtracting 2583 from 2670 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 20066.33 and a remainder of 0.087.
