6623715 divided by 805 
The aim is to understand the frequency of 805 in 6623715.

Step 1:
When dividing 6 by 805, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 805

Advancing to step 2:
If we divide 66 by 805, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 805

Advancing to step 3:
If we divide 662 by 805, we get 0 and a remainder of 662.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 662 and we're left with 662.
Fetch the next digit (3) from the dividend, attach it to 662 and continue: 6623 / 805

Step 4:
6623 divided by 805 is 8 with a remainder of 183.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 6440 from 6623 to get 183.
Grab the next digit (7) from the dividend, add it to 183, then carry on: 1837 / 805

On to step 5:
805 goes into 1837 2 times with a remainder of 227.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Deduct 1610 from 1837 and we're left with 227.
Bring next digit (1) of the dividend behind the 227 and repeat the process: 2271 / 805

Moving on to step 6:
805 can be fit into 2271 2 times, resulting in a remainder of 661.
Use 2 as the next digit of our solution. 
Result so far: 822.0
If we take 1610 away from 2271, we end up with 661.
Bring next digit (5) of the dividend behind the 661 and repeat the process: 6615 / 805

On to step 7:
805 goes into 6615 8 times with a remainder of 175.
The next digit of our result is 8. 
Result so far: 8228.0
If we take 6440 away from 6615, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 8:
805 goes into 1750 2 times with a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 8228.2
Subtracting 1610 from 1750 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
805 can be fit into 1400 1 times, resulting in a remainder of 595.
Record the quotient 1 as the next digit in the result. 
Result so far: 8228.21
Subtract 805 from 1400 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 10:
805 goes into 5950 7 times with a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 8228.217
If we subtract 5635 from 5950, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 11:
The number 805 fits into 3150 3 times, leaving a remainder of 735.
The next digit of our result is 3. 
Result so far: 8228.2173
If we subtract 2415 from 3150, we get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 12:
805 goes into 7350 9 times with a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 8228.21739
Deduct 7245 from 7350 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 13:
1050 divided by 805 is 1 with a remainder of 245.
Use 1 as the next digit of our solution. 
Result so far: 8228.217391
Subtracting 805 from 1050 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 14:
When dividing 2450 by 805, we get 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 8228.2173913
Subtract 2415 from 2450 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 15:
805 goes into 350 0 times with a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 8228.2173913
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Our division results in 8228.2173913 with a remaining 3.5e-07.
