50750098 ÷ 131 
The aim is to understand the frequency of 131 in 50750098.

Moving on to step 1:
131 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 131

On to step 2:
If we divide 50 by 131, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 131

Going ahead to step 3:
131 can be fit into 507 3 times, resulting in a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 114 after subtracting 393 from 507.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 131

On to step 4:
If we divide 1145 by 131, we get 8 and a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 1048 from 1145 to get 97.
Take the next digit (0) from the dividend and append it to 97, then repeat: 970 / 131

Moving on to step 5:
131 can be fit into 970 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 387.0
Subtract 917 from 970 to get 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 131

Moving on to step 6:
131 goes into 530 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 3874.0
Subtracting 524 from 530 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 131

Step 7:
131 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 38740.0
Subtracting 0 from 69 leaves us with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 131

Advancing to step 8:
If we divide 698 by 131, we get 5 and a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 387405.0
The remainder is 43 after subtracting 655 from 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
131 goes into 430 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 387405.3
Subtracting 393 from 430 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
370 divided by 131 is 2 with a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 387405.32
If we take 262 away from 370, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 11:
1080 divided by 131 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 387405.328
If we take 1048 away from 1080, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
131 can be fit into 320 2 times, resulting in a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 387405.3282
If we subtract 262 from 320, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 13:
580 divided by 131 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 387405.32824
Subtracting 524 from 580 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
131 goes into 560 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 387405.328244
Subtracting 524 from 560 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 387405.328244, with a leftover of 3.6e-06.
