We look at the division of 33917193 by 811 
The aim is to understand the frequency of 811 in 33917193.

Moving on to step 1:
811 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 811

Step 2:
When dividing 33 by 811, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 811

Advancing to step 3:
The number 811 fits into 339 0 times, leaving a remainder of 339.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 339 leaves us with 339.
Append the next digit (1) from the dividend to 339 and continue with: 3391 / 811

Let's proceed to step 4:
The number 811 fits into 3391 4 times, leaving a remainder of 147.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3244 from 3391 and we're left with 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 811

Let's proceed to step 5:
If we divide 1477 by 811, we get 1 and a remainder of 666.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 811 from 1477, we get 666.
Take the next digit (1) from the dividend and append it to 666, then repeat: 6661 / 811

On to step 6:
When dividing 6661 by 811, we get 8 with a remainder of 173.
The number 8 becomes the next digit in our result. 
Result so far: 418.0
Subtracting 6488 from 6661 leaves us with 173.
Append the next digit (9) from the dividend to 173 and continue with: 1739 / 811

Advancing to step 7:
1739 divided by 811 is 2 with a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 4182.0
Deduct 1622 from 1739 and we're left with 117.
Append the next digit (3) from the dividend to 117 and continue with: 1173 / 811

Let's proceed to step 8:
If we divide 1173 by 811, we get 1 and a remainder of 362.
Write down 1 as next digit of the result. 
Result so far: 41821.0
The remainder is 362 after subtracting 811 from 1173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 9:
811 can be fit into 3620 4 times, resulting in a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 41821.4
Subtract 3244 from 3620 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 10:
The number 811 fits into 3760 4 times, leaving a remainder of 516.
Use 4 as the next digit of our solution. 
Result so far: 41821.44
If we subtract 3244 from 3760, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

The final outcome is 41821.44, with a leftover of 0.516.
