Let's divide 861077 by 217
The aim is to understand the frequency of 217 in 861077.

On to step 1:
217 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 217

On to step 2:
86 divided by 217 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 217

Moving on to step 3:
217 goes into 861 3 times with a remainder of 210.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 651 from 861, we get 210.
Include the next digit (0) from the dividend after 210, then repeat: 2100 / 217

On to step 4:
The number 217 fits into 2100 9 times, leaving a remainder of 147.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 1953 from 2100 and we're left with 147.
Fetch the next digit (7) from the dividend, attach it to 147 and continue: 1477 / 217

Step 5:
217 goes into 1477 6 times with a remainder of 175.
The next digit of our result is 6. 
Result so far: 396.0
If we subtract 1302 from 1477, we get 175.
Fetch the next digit (7) from the dividend, attach it to 175 and continue: 1757 / 217

Let's proceed to step 6:
If we divide 1757 by 217, we get 8 and a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 3968.0
Deduct 1736 from 1757 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
217 goes into 210 0 times with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 3968.0
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 8:
217 goes into 2100 9 times with a remainder of 147.
The number 9 becomes the next digit in our result. 
Result so far: 3968.09
Deduct 1953 from 2100 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
217 goes into 1470 6 times with a remainder of 168.
Write down 6 as next digit of the result. 
Result so far: 3968.096
Subtracting 1302 from 1470 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 10:
217 can be fit into 1680 7 times, resulting in a remainder of 161.
Record the quotient 7 as the next digit in the result. 
Result so far: 3968.0967
Subtracting 1519 from 1680 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 11:
217 can be fit into 1610 7 times, resulting in a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 3968.09677
Deduct 1519 from 1610 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

After the division, we end up with 3968.09677 and a remainder of 9.1e-05.
