Let's divide 98305210 by 131
The aim is to understand the frequency of 131 in 98305210.

Step 1:
When dividing 9 by 131, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 131

Moving on to step 2:
131 can be fit into 98 0 times, resulting in a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Take the next digit (3) from the dividend and append it to 98, then repeat: 983 / 131

Going ahead to step 3:
The number 131 fits into 983 7 times, leaving a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 917 from 983 to get 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 131

Let's proceed to step 4:
The number 131 fits into 660 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 655 from 660 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 131

Advancing to step 5:
131 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 750.0
If we subtract 0 from 55, we get 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 131

On to step 6:
131 can be fit into 552 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 7504.0
The remainder is 28 after subtracting 524 from 552.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 131

Moving on to step 7:
If we divide 281 by 131, we get 2 and a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 75042.0
Subtract 262 from 281 to get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 131

Step 8:
190 divided by 131 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 750421.0
The remainder is 59 after subtracting 131 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
131 can be fit into 590 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 750421.4
The remainder is 66 after subtracting 524 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
When dividing 660 by 131, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 750421.45
If we subtract 655 from 660, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
50 divided by 131 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 750421.45
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
The number 131 fits into 500 3 times, leaving a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 750421.4503
If we take 393 away from 500, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 13:
If we divide 1070 by 131, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 750421.45038
Subtracting 1048 from 1070 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
131 can be fit into 220 1 times, resulting in a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 750421.450381
The remainder is 89 after subtracting 131 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 15:
The number 131 fits into 890 6 times, leaving a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 750421.4503816
Subtracting 786 from 890 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 16:
The number 131 fits into 1040 7 times, leaving a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 750421.45038167
Subtracting 917 from 1040 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final result is 750421.45038167 with a remainder of 1.23e-07.
