We look at the division of 9879713 by 811 
The aim is to understand the frequency of 811 in 9879713.

Let's proceed to step 1:
9 divided by 811 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 811

Advancing to step 2:
811 goes into 98 0 times with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 811

Step 3:
The number 811 fits into 987 1 times, leaving a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 811 from 987, we get 176.
Grab the next digit (9) from the dividend, add it to 176, then carry on: 1769 / 811

Going ahead to step 4:
The number 811 fits into 1769 2 times, leaving a remainder of 147.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1622 away from 1769, we end up with 147.
Fetch the next digit (7) from the dividend, attach it to 147 and continue: 1477 / 811

Advancing to step 5:
The number 811 fits into 1477 1 times, leaving a remainder of 666.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtracting 811 from 1477 leaves us with 666.
Fetch the next digit (1) from the dividend, attach it to 666 and continue: 6661 / 811

Let's proceed to step 6:
The number 811 fits into 6661 8 times, leaving a remainder of 173.
Record the quotient 8 as the next digit in the result. 
Result so far: 1218.0
The remainder is 173 after subtracting 6488 from 6661.
Append the next digit (3) from the dividend to 173 and continue with: 1733 / 811

Going ahead to step 7:
811 can be fit into 1733 2 times, resulting in a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 12182.0
Deduct 1622 from 1733 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 8:
If we divide 1110 by 811, we get 1 and a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 12182.1
Deduct 811 from 1110 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 9:
811 goes into 2990 3 times with a remainder of 557.
Record the quotient 3 as the next digit in the result. 
Result so far: 12182.13
Subtracting 2433 from 2990 leaves us with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Going ahead to step 10:
811 can be fit into 5570 6 times, resulting in a remainder of 704.
Put 6 as the next digit of the answer. 
Result so far: 12182.136
The remainder is 704 after subtracting 4866 from 5570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Going ahead to step 11:
811 goes into 7040 8 times with a remainder of 552.
The next digit of our result is 8. 
Result so far: 12182.1368
Deduct 6488 from 7040 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 12:
811 goes into 5520 6 times with a remainder of 654.
Write down 6 as next digit of the result. 
Result so far: 12182.13686
If we subtract 4866 from 5520, we get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 13:
When dividing 6540 by 811, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 12182.136868
Subtracting 6488 from 6540 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
When dividing 520 by 811, we get 0 with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 12182.136868
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 15:
The number 811 fits into 5200 6 times, leaving a remainder of 334.
Put 6 as the next digit of the answer. 
Result so far: 12182.13686806
If we take 4866 away from 5200, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

After the division, we end up with 12182.13686806 and a remainder of 3.34e-07.
