We look at the division of 92800907 by 861 
The aim is to understand the frequency of 861 in 92800907.

Going ahead to step 1:
The number 861 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 861

Step 2:
When dividing 92 by 861, we get 0 with a remainder of 92.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 92 after subtracting 0 from 92.
Take the next digit (8) from the dividend and append it to 92, then repeat: 928 / 861

Let's proceed to step 3:
The number 861 fits into 928 1 times, leaving a remainder of 67.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 67 after subtracting 861 from 928.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 861

Advancing to step 4:
861 can be fit into 670 0 times, resulting in a remainder of 670.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 670 leaves us with 670.
Bring next digit (0) of the dividend behind the 670 and repeat the process: 6700 / 861

Let's proceed to step 5:
861 goes into 6700 7 times with a remainder of 673.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtract 6027 from 6700 to get 673.
Grab the next digit (9) from the dividend, add it to 673, then carry on: 6739 / 861

Advancing to step 6:
861 can be fit into 6739 7 times, resulting in a remainder of 712.
The next digit of our result is 7. 
Result so far: 1077.0
If we take 6027 away from 6739, we end up with 712.
Grab the next digit (0) from the dividend, add it to 712, then carry on: 7120 / 861

Let's proceed to step 7:
7120 divided by 861 is 8 with a remainder of 232.
The next digit of our result is 8. 
Result so far: 10778.0
If we subtract 6888 from 7120, we get 232.
Grab the next digit (7) from the dividend, add it to 232, then carry on: 2327 / 861

Moving on to step 8:
861 goes into 2327 2 times with a remainder of 605.
The next digit of our result is 2. 
Result so far: 107782.0
Subtracting 1722 from 2327 leaves us with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 9:
6050 divided by 861 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 107782.7
If we take 6027 away from 6050, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 10:
861 goes into 230 0 times with a remainder of 230.
The next digit of our result is 0. 
Result so far: 107782.7
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
The number 861 fits into 2300 2 times, leaving a remainder of 578.
Write down 2 as next digit of the result. 
Result so far: 107782.702
The remainder is 578 after subtracting 1722 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 12:
If we divide 5780 by 861, we get 6 and a remainder of 614.
Put 6 as the next digit of the answer. 
Result so far: 107782.7026
Subtracting 5166 from 5780 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 13:
861 can be fit into 6140 7 times, resulting in a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 107782.70267
Subtract 6027 from 6140 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 14:
1130 divided by 861 is 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 107782.702671
If we take 861 away from 1130, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 15:
The number 861 fits into 2690 3 times, leaving a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 107782.7026713
If we take 2583 away from 2690, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 16:
861 can be fit into 1070 1 times, resulting in a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 107782.70267131
Subtracting 861 from 1070 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The final result is 107782.70267131 with a remainder of 2.09e-07.
