58430561 divided by 849 
The aim is to understand the frequency of 849 in 58430561.

Going ahead to step 1:
849 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 849

On to step 2:
If we divide 58 by 849, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 849

Let's proceed to step 3:
849 can be fit into 584 0 times, resulting in a remainder of 584.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 584 and we're left with 584.
Fetch the next digit (3) from the dividend, attach it to 584 and continue: 5843 / 849

Going ahead to step 4:
If we divide 5843 by 849, we get 6 and a remainder of 749.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 749 after subtracting 5094 from 5843.
Grab the next digit (0) from the dividend, add it to 749, then carry on: 7490 / 849

Moving on to step 5:
7490 divided by 849 is 8 with a remainder of 698.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtract 6792 from 7490 to get 698.
Grab the next digit (5) from the dividend, add it to 698, then carry on: 6985 / 849

Moving on to step 6:
849 can be fit into 6985 8 times, resulting in a remainder of 193.
The number 8 becomes the next digit in our result. 
Result so far: 688.0
The remainder is 193 after subtracting 6792 from 6985.
Grab the next digit (6) from the dividend, add it to 193, then carry on: 1936 / 849

Moving on to step 7:
849 goes into 1936 2 times with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 6882.0
Subtracting 1698 from 1936 leaves us with 238.
Fetch the next digit (1) from the dividend, attach it to 238 and continue: 2381 / 849

Let's proceed to step 8:
849 can be fit into 2381 2 times, resulting in a remainder of 683.
Put 2 as the next digit of the answer. 
Result so far: 68822.0
Deduct 1698 from 2381 and we're left with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Step 9:
The number 849 fits into 6830 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 68822.8
Subtracting 6792 from 6830 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
849 goes into 380 0 times with a remainder of 380.
The next digit of our result is 0. 
Result so far: 68822.8
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
When dividing 3800 by 849, we get 4 with a remainder of 404.
Put 4 as the next digit of the answer. 
Result so far: 68822.804
Subtract 3396 from 3800 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 12:
4040 divided by 849 is 4 with a remainder of 644.
Record the quotient 4 as the next digit in the result. 
Result so far: 68822.8044
If we subtract 3396 from 4040, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

The final result is 68822.8044 with a remainder of 0.00644.
