We look at the division of 71194781 by 849 
The aim is to understand the frequency of 849 in 71194781.

On to step 1:
If we divide 7 by 849, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 849

Going ahead to step 2:
If we divide 71 by 849, we get 0 and a remainder of 71.
The next digit of our result is 0. 
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:
If we divide 711 by 849, we get 0 and a remainder of 711.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 711, we end up with 711.
Fetch the next digit (9) from the dividend, attach it to 711 and continue: 7119 / 849

Let's proceed to step 4:
849 goes into 7119 8 times with a remainder of 327.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6792 from 7119 and we're left with 327.
Grab the next digit (4) from the dividend, add it to 327, then carry on: 3274 / 849

On to step 5:
If we divide 3274 by 849, we get 3 and a remainder of 727.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 2547 from 3274, we get 727.
Append the next digit (7) from the dividend to 727 and continue with: 7277 / 849

Step 6:
849 can be fit into 7277 8 times, resulting in a remainder of 485.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
Subtract 6792 from 7277 to get 485.
Fetch the next digit (8) from the dividend, attach it to 485 and continue: 4858 / 849

Step 7:
849 can be fit into 4858 5 times, resulting in a remainder of 613.
Put 5 as the next digit of the answer. 
Result so far: 8385.0
Subtract 4245 from 4858 to get 613.
Bring next digit (1) of the dividend behind the 613 and repeat the process: 6131 / 849

Step 8:
849 can be fit into 6131 7 times, resulting in a remainder of 188.
The next digit of our result is 7. 
Result so far: 83857.0
Subtracting 5943 from 6131 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 9:
849 goes into 1880 2 times with a remainder of 182.
The number 2 becomes the next digit in our result. 
Result so far: 83857.2
If we take 1698 away from 1880, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 10:
The number 849 fits into 1820 2 times, leaving a remainder of 122.
Record the quotient 2 as the next digit in the result. 
Result so far: 83857.22
Subtracting 1698 from 1820 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Our division results in 83857.22 with a remaining 0.122.
