We look at the division of 91604962 by 811 
The aim is to understand the frequency of 811 in 91604962.

Advancing to step 1:
811 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 811

Going ahead to step 2:
91 divided by 811 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 811

Advancing to step 3:
811 goes into 916 1 times with a remainder of 105.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 811 from 916 to get 105.
Include the next digit (0) from the dividend after 105, then repeat: 1050 / 811

Step 4:
If we divide 1050 by 811, we get 1 and a remainder of 239.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 811 away from 1050, we end up with 239.
Fetch the next digit (4) from the dividend, attach it to 239 and continue: 2394 / 811

On to step 5:
2394 divided by 811 is 2 with a remainder of 772.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Subtracting 1622 from 2394 leaves us with 772.
Fetch the next digit (9) from the dividend, attach it to 772 and continue: 7729 / 811

Going ahead to step 6:
811 goes into 7729 9 times with a remainder of 430.
The next digit of our result is 9. 
Result so far: 1129.0
Subtract 7299 from 7729 to get 430.
Append the next digit (6) from the dividend to 430 and continue with: 4306 / 811

Step 7:
The number 811 fits into 4306 5 times, leaving a remainder of 251.
The number 5 becomes the next digit in our result. 
Result so far: 11295.0
Deduct 4055 from 4306 and we're left with 251.
Append the next digit (2) from the dividend to 251 and continue with: 2512 / 811

Advancing to step 8:
When dividing 2512 by 811, we get 3 with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 112953.0
The remainder is 79 after subtracting 2433 from 2512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
When dividing 790 by 811, we get 0 with a remainder of 790.
Put 0 as the next digit of the answer. 
Result so far: 112953.0
If we take 0 away from 790, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 10:
When dividing 7900 by 811, we get 9 with a remainder of 601.
Use 9 as the next digit of our solution. 
Result so far: 112953.09
Subtract 7299 from 7900 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Let's proceed to step 11:
The number 811 fits into 6010 7 times, leaving a remainder of 333.
The next digit of our result is 7. 
Result so far: 112953.097
Deduct 5677 from 6010 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 12:
811 goes into 3330 4 times with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 112953.0974
If we subtract 3244 from 3330, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 13:
811 goes into 860 1 times with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 112953.09741
Deduct 811 from 860 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
If we divide 490 by 811, we get 0 and a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 112953.09741
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 15:
When dividing 4900 by 811, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 112953.0974106
If we take 4866 away from 4900, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 16:
811 goes into 340 0 times with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 112953.0974106
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

After the division, we end up with 112953.0974106 and a remainder of 3.4e-07.
