86049172 ÷ 849 
The aim is to understand the frequency of 849 in 86049172.

Let's proceed to step 1:
If we divide 8 by 849, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 849

Let's proceed to step 2:
849 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 849

Moving on to step 3:
849 goes into 860 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 849 from 860 and we're left with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 849

Let's proceed to step 4:
849 goes into 114 0 times with a remainder of 114.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 114 and we're left with 114.
Fetch the next digit (9) from the dividend, attach it to 114 and continue: 1149 / 849

Let's proceed to step 5:
When dividing 1149 by 849, we get 1 with a remainder of 300.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we subtract 849 from 1149, we get 300.
Fetch the next digit (1) from the dividend, attach it to 300 and continue: 3001 / 849

Moving on to step 6:
The number 849 fits into 3001 3 times, leaving a remainder of 454.
The number 3 becomes the next digit in our result. 
Result so far: 1013.0
The remainder is 454 after subtracting 2547 from 3001.
Take the next digit (7) from the dividend and append it to 454, then repeat: 4547 / 849

Moving on to step 7:
4547 divided by 849 is 5 with a remainder of 302.
Record the quotient 5 as the next digit in the result. 
Result so far: 10135.0
The remainder is 302 after subtracting 4245 from 4547.
Grab the next digit (2) from the dividend, add it to 302, then carry on: 3022 / 849

Let's proceed to step 8:
849 goes into 3022 3 times with a remainder of 475.
The next digit of our result is 3. 
Result so far: 101353.0
Subtracting 2547 from 3022 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 9:
849 goes into 4750 5 times with a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 101353.5
Subtract 4245 from 4750 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 10:
849 can be fit into 5050 5 times, resulting in a remainder of 805.
Write down 5 as next digit of the result. 
Result so far: 101353.55
Subtracting 4245 from 5050 leaves us with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

The final result is 101353.55 with a remainder of 0.805.
