Let's divide 866107 by 77
The aim is to understand the frequency of 77 in 866107.

Step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 77

Step 2:
77 goes into 86 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 77 from 86, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 77

On to step 3:
When dividing 96 by 77, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 77 from 96 to get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 77

Let's proceed to step 4:
If we divide 191 by 77, we get 2 and a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we subtract 154 from 191, we get 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 77

Moving on to step 5:
When dividing 370 by 77, we get 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 1124.0
Subtracting 308 from 370 leaves us with 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 77

Advancing to step 6:
77 goes into 627 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 11248.0
Deduct 616 from 627 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 11248.1
If we subtract 77 from 110, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
77 goes into 330 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 11248.14
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
220 divided by 77 is 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 11248.142
The remainder is 66 after subtracting 154 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
77 goes into 660 8 times with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 11248.1428
Subtract 616 from 660 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
440 divided by 77 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 11248.14285
If we take 385 away from 440, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 12:
550 divided by 77 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 11248.142857
Subtracting 539 from 550 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
110 divided by 77 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 11248.1428571
If we subtract 77 from 110, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 14:
330 divided by 77 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 11248.14285714
Deduct 308 from 330 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 11248.14285714 with a balance of 2.2e-08.
