We look at the division of 7906222 by 805 
The aim is to understand the frequency of 805 in 7906222.

On to step 1:
805 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 805

On to step 2:
When dividing 79 by 805, we get 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 805

Step 3:
790 divided by 805 is 0 with a remainder of 790.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 790 after subtracting 0 from 790.
Include the next digit (6) from the dividend after 790, then repeat: 7906 / 805

On to step 4:
If we divide 7906 by 805, we get 9 and a remainder of 661.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7245 from 7906 to get 661.
Take the next digit (2) from the dividend and append it to 661, then repeat: 6612 / 805

On to step 5:
6612 divided by 805 is 8 with a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 6440 away from 6612, we end up with 172.
Append the next digit (2) from the dividend to 172 and continue with: 1722 / 805

Going ahead to step 6:
805 goes into 1722 2 times with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 982.0
Deduct 1610 from 1722 and we're left with 112.
Bring next digit (2) of the dividend behind the 112 and repeat the process: 1122 / 805

Going ahead to step 7:
The number 805 fits into 1122 1 times, leaving a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 9821.0
Subtract 805 from 1122 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 8:
The number 805 fits into 3170 3 times, leaving a remainder of 755.
Record the quotient 3 as the next digit in the result. 
Result so far: 9821.3
Deduct 2415 from 3170 and we're left with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

On to step 9:
When dividing 7550 by 805, we get 9 with a remainder of 305.
Put 9 as the next digit of the answer. 
Result so far: 9821.39
If we take 7245 away from 7550, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 10:
When dividing 3050 by 805, we get 3 with a remainder of 635.
Record the quotient 3 as the next digit in the result. 
Result so far: 9821.393
Subtracting 2415 from 3050 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 11:
805 can be fit into 6350 7 times, resulting in a remainder of 715.
The number 7 becomes the next digit in our result. 
Result so far: 9821.3937
Deduct 5635 from 6350 and we're left with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

On to step 12:
If we divide 7150 by 805, we get 8 and a remainder of 710.
The number 8 becomes the next digit in our result. 
Result so far: 9821.39378
Subtracting 6440 from 7150 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 13:
7100 divided by 805 is 8 with a remainder of 660.
Put 8 as the next digit of the answer. 
Result so far: 9821.393788
Deduct 6440 from 7100 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Our division results in 9821.393788 with a remaining 6.6e-05.
