We're dividing 12317453 by 807 
The aim is to understand the frequency of 807 in 12317453.

Advancing to step 1:
If we divide 1 by 807, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 807

On to step 2:
The number 807 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 807

Moving on to step 3:
807 goes into 123 0 times with a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 807

On to step 4:
The number 807 fits into 1231 1 times, leaving a remainder of 424.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 424 after subtracting 807 from 1231.
Bring next digit (7) of the dividend behind the 424 and repeat the process: 4247 / 807

Let's proceed to step 5:
If we divide 4247 by 807, we get 5 and a remainder of 212.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 4035 away from 4247, we end up with 212.
Grab the next digit (4) from the dividend, add it to 212, then carry on: 2124 / 807

On to step 6:
If we divide 2124 by 807, we get 2 and a remainder of 510.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we subtract 1614 from 2124, we get 510.
Grab the next digit (5) from the dividend, add it to 510, then carry on: 5105 / 807

Advancing to step 7:
5105 divided by 807 is 6 with a remainder of 263.
Write down 6 as next digit of the result. 
Result so far: 1526.0
The remainder is 263 after subtracting 4842 from 5105.
Take the next digit (3) from the dividend and append it to 263, then repeat: 2633 / 807

Let's proceed to step 8:
2633 divided by 807 is 3 with a remainder of 212.
Write down 3 as next digit of the result. 
Result so far: 15263.0
The remainder is 212 after subtracting 2421 from 2633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 9:
807 can be fit into 2120 2 times, resulting in a remainder of 506.
The next digit of our result is 2. 
Result so far: 15263.2
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.

Advancing to step 10:
5060 divided by 807 is 6 with a remainder of 218.
Use 6 as the next digit of our solution. 
Result so far: 15263.26
If we subtract 4842 from 5060, we get 218.
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 11:
2180 divided by 807 is 2 with a remainder of 566.
The next digit of our result is 2. 
Result so far: 15263.262
Subtracting 1614 from 2180 leaves us 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.

Let's proceed to step 12:
If we divide 5660 by 807, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 15263.2627
Subtracting 5649 from 5660 leaves us 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.

Step 13:
The number 807 fits into 110 0 times, leaving a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 15263.2627
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 14:
If we divide 1100 by 807, we get 1 and a remainder of 293.
Use 1 as the next digit of our solution. 
Result so far: 15263.262701
Deduct 807 from 1100 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 15:
If we divide 2930 by 807, we get 3 and a remainder of 509.
Put 3 as the next digit of the answer. 
Result so far: 15263.2627013
The remainder is 509 after subtracting 2421 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 16:
The number 807 fits into 5090 6 times, leaving a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 15263.26270136
Subtracting 4842 from 5090 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 15263.26270136 with a remaining 2.48e-07.
