We look at the division of 7119429 by 849 
The aim is to understand the frequency of 849 in 7119429.

Let's proceed to step 1:
7 divided by 849 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 849

Moving on to step 2:
71 divided by 849 is 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 849

Let's proceed to step 3:
When dividing 711 by 849, we get 0 with a remainder of 711.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 711, we get 711.
Fetch the next digit (9) from the dividend, attach it to 711 and continue: 7119 / 849

Step 4:
849 can be fit into 7119 8 times, resulting in a remainder of 327.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 6792 from 7119, we get 327.
Append the next digit (4) from the dividend to 327 and continue with: 3274 / 849

Step 5:
When dividing 3274 by 849, we get 3 with a remainder of 727.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 2547 from 3274, we get 727.
Grab the next digit (2) from the dividend, add it to 727, then carry on: 7272 / 849

On to step 6:
The number 849 fits into 7272 8 times, leaving a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 838.0
Subtract 6792 from 7272 to get 480.
Fetch the next digit (9) from the dividend, attach it to 480 and continue: 4809 / 849

Moving on to step 7:
If we divide 4809 by 849, we get 5 and a remainder of 564.
The number 5 becomes the next digit in our result. 
Result so far: 8385.0
If we take 4245 away from 4809, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 8:
5640 divided by 849 is 6 with a remainder of 546.
The next digit of our result is 6. 
Result so far: 8385.6
Subtract 5094 from 5640 to get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 9:
If we divide 5460 by 849, we get 6 and a remainder of 366.
The number 6 becomes the next digit in our result. 
Result so far: 8385.66
Subtracting 5094 from 5460 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

The final outcome is 8385.66, with a leftover of 0.366.
