We look at the division of 49500748 by 811 
The aim is to understand the frequency of 811 in 49500748.

On to step 1:
When dividing 4 by 811, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 811

Going ahead to step 2:
49 divided by 811 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 811

Going ahead to step 3:
If we divide 495 by 811, we get 0 and a remainder of 495.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 495 after subtracting 0 from 495.
Append the next digit (0) from the dividend to 495 and continue with: 4950 / 811

Going ahead to step 4:
4950 divided by 811 is 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 4866 away from 4950, we end up with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 811

Moving on to step 5:
The number 811 fits into 840 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we take 811 away from 840, we end up with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 811

Advancing to step 6:
811 goes into 297 0 times with a remainder of 297.
Put 0 as the next digit of the answer. 
Result so far: 610.0
Deduct 0 from 297 and we're left with 297.
Take the next digit (4) from the dividend and append it to 297, then repeat: 2974 / 811

Let's proceed to step 7:
2974 divided by 811 is 3 with a remainder of 541.
Put 3 as the next digit of the answer. 
Result so far: 6103.0
If we subtract 2433 from 2974, we get 541.
Bring next digit (8) of the dividend behind the 541 and repeat the process: 5418 / 811

On to step 8:
811 goes into 5418 6 times with a remainder of 552.
The next digit of our result is 6. 
Result so far: 61036.0
Deduct 4866 from 5418 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 9:
When dividing 5520 by 811, we get 6 with a remainder of 654.
The next digit of our result is 6. 
Result so far: 61036.6
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.

Moving on to step 10:
811 can be fit into 6540 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 61036.68
The remainder is 52 after subtracting 6488 from 6540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
If we divide 520 by 811, we get 0 and a remainder of 520.
The next digit of our result is 0. 
Result so far: 61036.68
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 12:
811 goes into 5200 6 times with a remainder of 334.
The next digit of our result is 6. 
Result so far: 61036.6806
If we subtract 4866 from 5200, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 13:
If we divide 3340 by 811, we get 4 and a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 61036.68064
Subtract 3244 from 3340 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
The number 811 fits into 960 1 times, leaving a remainder of 149.
Record the quotient 1 as the next digit in the result. 
Result so far: 61036.680641
Deduct 811 from 960 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 15:
1490 divided by 811 is 1 with a remainder of 679.
Use 1 as the next digit of our solution. 
Result so far: 61036.6806411
If we subtract 811 from 1490, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

The quotient of the division is 61036.6806411, and the remainder is 6.79e-06.
