We're dividing 13886540 by 807 
The aim is to understand the frequency of 807 in 13886540.

Let's proceed to step 1:
1 divided by 807 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 807

Moving on to step 2:
The number 807 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 807

Going ahead to step 3:
If we divide 138 by 807, we get 0 and a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Take the next digit (8) from the dividend and append it to 138, then repeat: 1388 / 807

Let's proceed to step 4:
1388 divided by 807 is 1 with a remainder of 581.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 807 away from 1388, we end up with 581.
Fetch the next digit (6) from the dividend, attach it to 581 and continue: 5816 / 807

Let's proceed to step 5:
The number 807 fits into 5816 7 times, leaving a remainder of 167.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 5649 from 5816 and we're left with 167.
Fetch the next digit (5) from the dividend, attach it to 167 and continue: 1675 / 807

Moving on to step 6:
807 can be fit into 1675 2 times, resulting in a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 172.0
Subtracting 1614 from 1675 leaves us with 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 807

Let's proceed to step 7:
When dividing 614 by 807, we get 0 with a remainder of 614.
Use 0 as the next digit of our solution. 
Result so far: 1720.0
Subtracting 0 from 614 leaves us with 614.
Take the next digit (0) from the dividend and append it to 614, then repeat: 6140 / 807

Advancing to step 8:
If we divide 6140 by 807, we get 7 and a remainder of 491.
Put 7 as the next digit of the answer. 
Result so far: 17207.0
Deduct 5649 from 6140 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 9:
If we divide 4910 by 807, we get 6 and a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 17207.6
The remainder is 68 after subtracting 4842 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
If we divide 680 by 807, we get 0 and a remainder of 680.
The next digit of our result is 0. 
Result so far: 17207.6
If we subtract 0 from 680, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 11:
6800 divided by 807 is 8 with a remainder of 344.
Put 8 as the next digit of the answer. 
Result so far: 17207.608
Subtract 6456 from 6800 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 12:
807 goes into 3440 4 times with a remainder of 212.
The next digit of our result is 4. 
Result so far: 17207.6084
Subtracting 3228 from 3440 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
2120 divided by 807 is 2 with a remainder of 506.
Put 2 as the next digit of the answer. 
Result so far: 17207.60842
Subtract 1614 from 2120 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 14:
5060 divided by 807 is 6 with a remainder of 218.
Put 6 as the next digit of the answer. 
Result so far: 17207.608426
The remainder is 218 after subtracting 4842 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 15:
If we divide 2180 by 807, we get 2 and a remainder of 566.
Write down 2 as next digit of the result. 
Result so far: 17207.6084262
If we take 1614 away from 2180, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 16:
The number 807 fits into 5660 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 17207.60842627
If we take 5649 away from 5660, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 17207.60842627 with a remainder of 1.1e-08.
