We're dividing 75384126 by 131 
The aim is to understand the frequency of 131 in 75384126.

On to step 1:
7 divided by 131 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 131

Let's proceed to step 2:
131 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 131

Moving on to step 3:
If we divide 753 by 131, we get 5 and a remainder of 98.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 655 from 753, we get 98.
Fetch the next digit (8) from the dividend, attach it to 98 and continue: 988 / 131

Going ahead to step 4:
The number 131 fits into 988 7 times, leaving a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Subtract 917 from 988 to get 71.
Include the next digit (4) from the dividend after 71, then repeat: 714 / 131

Moving on to step 5:
If we divide 714 by 131, we get 5 and a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 575.0
Deduct 655 from 714 and we're left with 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 131

Advancing to step 6:
131 can be fit into 591 4 times, resulting in a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 5754.0
The remainder is 67 after subtracting 524 from 591.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 131

On to step 7:
If we divide 672 by 131, we get 5 and a remainder of 17.
The next digit of our result is 5. 
Result so far: 57545.0
If we subtract 655 from 672, we get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 131

Moving on to step 8:
The number 131 fits into 176 1 times, leaving a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 575451.0
If we take 131 away from 176, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
131 can be fit into 450 3 times, resulting in a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 575451.3
Subtract 393 from 450 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
131 can be fit into 570 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 575451.34
If we take 524 away from 570, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
131 goes into 460 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 575451.343
If we take 393 away from 460, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 12:
131 goes into 670 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 575451.3435
Subtract 655 from 670 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
When dividing 150 by 131, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 575451.34351
Subtract 131 from 150 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
If we divide 190 by 131, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 575451.343511
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.

The final result is 575451.343511 with a remainder of 5.9e-06.
