We look at the division of 99580829 by 849 
The aim is to understand the frequency of 849 in 99580829.

Let's proceed to step 1:
When dividing 9 by 849, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 849

Step 2:
849 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 849

Going ahead to step 3:
The number 849 fits into 995 1 times, leaving a remainder of 146.
The next digit of our result is 1. 
Result so far: 1.0
If we take 849 away from 995, we end up with 146.
Grab the next digit (8) from the dividend, add it to 146, then carry on: 1468 / 849

Moving on to step 4:
849 goes into 1468 1 times with a remainder of 619.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 849 away from 1468, we end up with 619.
Include the next digit (0) from the dividend after 619, then repeat: 6190 / 849

Going ahead to step 5:
If we divide 6190 by 849, we get 7 and a remainder of 247.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we subtract 5943 from 6190, we get 247.
Append the next digit (8) from the dividend to 247 and continue with: 2478 / 849

Advancing to step 6:
2478 divided by 849 is 2 with a remainder of 780.
The number 2 becomes the next digit in our result. 
Result so far: 1172.0
Deduct 1698 from 2478 and we're left with 780.
Include the next digit (2) from the dividend after 780, then repeat: 7802 / 849

Going ahead to step 7:
When dividing 7802 by 849, we get 9 with a remainder of 161.
Write down 9 as next digit of the result. 
Result so far: 11729.0
Subtract 7641 from 7802 to get 161.
Take the next digit (9) from the dividend and append it to 161, then repeat: 1619 / 849

On to step 8:
849 goes into 1619 1 times with a remainder of 770.
Record the quotient 1 as the next digit in the result. 
Result so far: 117291.0
Deduct 849 from 1619 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 9:
The number 849 fits into 7700 9 times, leaving a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 117291.9
Subtract 7641 from 7700 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
The number 849 fits into 590 0 times, leaving a remainder of 590.
The number 0 becomes the next digit in our result. 
Result so far: 117291.9
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 11:
When dividing 5900 by 849, we get 6 with a remainder of 806.
The number 6 becomes the next digit in our result. 
Result so far: 117291.906
If we take 5094 away from 5900, we end up with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Moving on to step 12:
When dividing 8060 by 849, we get 9 with a remainder of 419.
Record the quotient 9 as the next digit in the result. 
Result so far: 117291.9069
Subtract 7641 from 8060 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 13:
4190 divided by 849 is 4 with a remainder of 794.
Use 4 as the next digit of our solution. 
Result so far: 117291.90694
Deduct 3396 from 4190 and we're left with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

On to step 14:
When dividing 7940 by 849, we get 9 with a remainder of 299.
Record the quotient 9 as the next digit in the result. 
Result so far: 117291.906949
The remainder is 299 after subtracting 7641 from 7940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 15:
If we divide 2990 by 849, we get 3 and a remainder of 443.
Write down 3 as next digit of the result. 
Result so far: 117291.9069493
Subtracting 2547 from 2990 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 16:
849 goes into 4430 5 times with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 117291.90694935
If we subtract 4245 from 4430, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

After the division, we end up with 117291.90694935 and a remainder of 1.85e-07.
