We divide 8656401 by 806
The aim is to understand the frequency of 806 in 8656401.

Advancing to step 1:
When dividing 8 by 806, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 806

Moving on to step 2:
The number 806 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 806

Moving on to step 3:
865 divided by 806 is 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 806 from 865 to get 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 806

Going ahead to step 4:
The number 806 fits into 596 0 times, leaving a remainder of 596.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 596 leaves us with 596.
Bring next digit (4) of the dividend behind the 596 and repeat the process: 5964 / 806

On to step 5:
When dividing 5964 by 806, we get 7 with a remainder of 322.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtract 5642 from 5964 to get 322.
Grab the next digit (0) from the dividend, add it to 322, then carry on: 3220 / 806

Moving on to step 6:
If we divide 3220 by 806, we get 3 and a remainder of 802.
The number 3 becomes the next digit in our result. 
Result so far: 1073.0
If we take 2418 away from 3220, we end up with 802.
Include the next digit (1) from the dividend after 802, then repeat: 8021 / 806

Moving on to step 7:
8021 divided by 806 is 9 with a remainder of 767.
Record the quotient 9 as the next digit in the result. 
Result so far: 10739.0
Deduct 7254 from 8021 and we're left with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

On to step 8:
If we divide 7670 by 806, we get 9 and a remainder of 416.
The next digit of our result is 9. 
Result so far: 10739.9
The remainder is 416 after subtracting 7254 from 7670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 9:
When dividing 4160 by 806, we get 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 10739.95
Deduct 4030 from 4160 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
When dividing 1300 by 806, we get 1 with a remainder of 494.
Put 1 as the next digit of the answer. 
Result so far: 10739.951
If we take 806 away from 1300, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 11:
806 can be fit into 4940 6 times, resulting in a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 10739.9516
If we take 4836 away from 4940, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
1040 divided by 806 is 1 with a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 10739.95161
If we subtract 806 from 1040, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 13:
806 goes into 2340 2 times with a remainder of 728.
Write down 2 as next digit of the result. 
Result so far: 10739.951612
If we take 1612 away from 2340, we end up with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Let's proceed to step 14:
If we divide 7280 by 806, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 10739.9516129
Subtracting 7254 from 7280 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 15:
When dividing 260 by 806, we get 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 10739.9516129
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final result is 10739.9516129 with a remainder of 2.6e-07.
