We look at the division of 1394059 by 849 
The aim is to understand the frequency of 849 in 1394059.

Step 1:
When dividing 1 by 849, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 849

Going ahead to step 2:
When dividing 13 by 849, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 849

Going ahead to step 3:
When dividing 139 by 849, we get 0 with a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 139, we get 139.
Bring next digit (4) of the dividend behind the 139 and repeat the process: 1394 / 849

Going ahead to step 4:
849 can be fit into 1394 1 times, resulting in a remainder of 545.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 849 from 1394 leaves us with 545.
Append the next digit (0) from the dividend to 545 and continue with: 5450 / 849

Moving on to step 5:
The number 849 fits into 5450 6 times, leaving a remainder of 356.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 5094 from 5450 to get 356.
Append the next digit (5) from the dividend to 356 and continue with: 3565 / 849

On to step 6:
The number 849 fits into 3565 4 times, leaving a remainder of 169.
Use 4 as the next digit of our solution. 
Result so far: 164.0
If we subtract 3396 from 3565, we get 169.
Append the next digit (9) from the dividend to 169 and continue with: 1699 / 849

Step 7:
1699 divided by 849 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1642.0
Subtract 1698 from 1699 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
If we divide 10 by 849, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 1642.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
849 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 1642.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 1642.0 with a remainder of 0.1.
