30136213 ÷ 849 
The aim is to understand the frequency of 849 in 30136213.

Step 1:
When dividing 3 by 849, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 849

On to step 2:
849 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 849

Moving on to step 3:
When dividing 301 by 849, we get 0 with a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 301 to get 301.
Bring next digit (3) of the dividend behind the 301 and repeat the process: 3013 / 849

On to step 4:
849 can be fit into 3013 3 times, resulting in a remainder of 466.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2547 from 3013, we get 466.
Bring next digit (6) of the dividend behind the 466 and repeat the process: 4666 / 849

Going ahead to step 5:
When dividing 4666 by 849, we get 5 with a remainder of 421.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 4245 away from 4666, we end up with 421.
Append the next digit (2) from the dividend to 421 and continue with: 4212 / 849

Moving on to step 6:
849 can be fit into 4212 4 times, resulting in a remainder of 816.
The next digit of our result is 4. 
Result so far: 354.0
The remainder is 816 after subtracting 3396 from 4212.
Take the next digit (1) from the dividend and append it to 816, then repeat: 8161 / 849

Advancing to step 7:
If we divide 8161 by 849, we get 9 and a remainder of 520.
Write down 9 as next digit of the result. 
Result so far: 3549.0
Subtract 7641 from 8161 to get 520.
Fetch the next digit (3) from the dividend, attach it to 520 and continue: 5203 / 849

On to step 8:
If we divide 5203 by 849, we get 6 and a remainder of 109.
Use 6 as the next digit of our solution. 
Result so far: 35496.0
If we take 5094 away from 5203, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
The number 849 fits into 1090 1 times, leaving a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 35496.1
If we subtract 849 from 1090, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 10:
849 goes into 2410 2 times with a remainder of 712.
Put 2 as the next digit of the answer. 
Result so far: 35496.12
Subtracting 1698 from 2410 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Step 11:
849 goes into 7120 8 times with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 35496.128
If we subtract 6792 from 7120, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 12:
3280 divided by 849 is 3 with a remainder of 733.
Record the quotient 3 as the next digit in the result. 
Result so far: 35496.1283
If we take 2547 away from 3280, we end up with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Moving on to step 13:
7330 divided by 849 is 8 with a remainder of 538.
Write down 8 as next digit of the result. 
Result so far: 35496.12838
If we subtract 6792 from 7330, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 14:
5380 divided by 849 is 6 with a remainder of 286.
Write down 6 as next digit of the result. 
Result so far: 35496.128386
If we take 5094 away from 5380, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 15:
When dividing 2860 by 849, we get 3 with a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 35496.1283863
If we subtract 2547 from 2860, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 16:
The number 849 fits into 3130 3 times, leaving a remainder of 583.
Write down 3 as next digit of the result. 
Result so far: 35496.12838633
Subtract 2547 from 3130 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

After the division, we end up with 35496.12838633 and a remainder of 5.83e-07.
