We look at the division of 4140769 by 807 
The aim is to understand the frequency of 807 in 4140769.

Advancing to step 1:
4 divided by 807 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 807

Let's proceed to step 2:
41 divided by 807 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 807

Let's proceed to step 3:
414 divided by 807 is 0 with a remainder of 414.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 414 leaves us with 414.
Append the next digit (0) from the dividend to 414 and continue with: 4140 / 807

Going ahead to step 4:
If we divide 4140 by 807, we get 5 and a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 4035 from 4140 leaves us with 105.
Take the next digit (7) from the dividend and append it to 105, then repeat: 1057 / 807

Moving on to step 5:
1057 divided by 807 is 1 with a remainder of 250.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 807 from 1057, we get 250.
Include the next digit (6) from the dividend after 250, then repeat: 2506 / 807

Let's proceed to step 6:
807 can be fit into 2506 3 times, resulting in a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 513.0
If we subtract 2421 from 2506, we get 85.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 807

Advancing to step 7:
If we divide 859 by 807, we get 1 and a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 5131.0
Deduct 807 from 859 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
520 divided by 807 is 0 with a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 5131.0
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 9:
When dividing 5200 by 807, we get 6 with a remainder of 358.
The next digit of our result is 6. 
Result so far: 5131.06
If we take 4842 away from 5200, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 10:
The number 807 fits into 3580 4 times, leaving a remainder of 352.
The next digit of our result is 4. 
Result so far: 5131.064
Subtract 3228 from 3580 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 11:
807 can be fit into 3520 4 times, resulting in a remainder of 292.
Record the quotient 4 as the next digit in the result. 
Result so far: 5131.0644
Subtract 3228 from 3520 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Our division results in 5131.0644 with a remaining 0.00292.
