Let's divide 21166356 by 131
The aim is to understand the frequency of 131 in 21166356.

Let's proceed to step 1:
When dividing 2 by 131, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 131

Let's proceed to step 2:
If we divide 21 by 131, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 131

Let's proceed to step 3:
The number 131 fits into 211 1 times, leaving a remainder of 80.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 80 after subtracting 131 from 211.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 131

Moving on to step 4:
131 goes into 806 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 786 from 806 leaves us with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 131

Moving on to step 5:
When dividing 206 by 131, we get 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we take 131 away from 206, we end up with 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 131

Step 6:
When dividing 753 by 131, we get 5 with a remainder of 98.
Record the quotient 5 as the next digit in the result. 
Result so far: 1615.0
Subtracting 655 from 753 leaves us with 98.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 131

Step 7:
985 divided by 131 is 7 with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 16157.0
Subtract 917 from 985 to get 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 131

Step 8:
131 can be fit into 686 5 times, resulting in a remainder of 31.
The next digit of our result is 5. 
Result so far: 161575.0
Deduct 655 from 686 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
310 divided by 131 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 161575.2
Deduct 262 from 310 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
If we divide 480 by 131, we get 3 and a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 161575.23
If we take 393 away from 480, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 11:
131 goes into 870 6 times with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 161575.236
The remainder is 84 after subtracting 786 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
131 can be fit into 840 6 times, resulting in a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 161575.2366
Deduct 786 from 840 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 161575.2366 with a balance of 0.00054.
