47397090 ÷ 131 
The aim is to understand the frequency of 131 in 47397090.

Step 1:
If we divide 4 by 131, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 131

On to step 2:
131 goes into 47 0 times with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 131

Advancing to step 3:
131 can be fit into 473 3 times, resulting in a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 80 after subtracting 393 from 473.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 131

Moving on to step 4:
131 goes into 809 6 times with a remainder of 23.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 786 from 809 leaves us with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 131

Step 5:
237 divided by 131 is 1 with a remainder of 106.
Use 1 as the next digit of our solution. 
Result so far: 361.0
Deduct 131 from 237 and we're left with 106.
Bring next digit (0) of the dividend behind the 106 and repeat the process: 1060 / 131

On to step 6:
131 can be fit into 1060 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 3618.0
If we take 1048 away from 1060, we end up with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 131

Moving on to step 7:
The number 131 fits into 129 0 times, leaving a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 36180.0
Subtract 0 from 129 to get 129.
Take the next digit (0) from the dividend and append it to 129, then repeat: 1290 / 131

On to step 8:
When dividing 1290 by 131, we get 9 with a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 361809.0
If we take 1179 away from 1290, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 9:
The number 131 fits into 1110 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 361809.8
If we take 1048 away from 1110, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
620 divided by 131 is 4 with a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 361809.84
Deduct 524 from 620 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
131 goes into 960 7 times with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 361809.847
If we take 917 away from 960, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 12:
When dividing 430 by 131, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 361809.8473
Subtract 393 from 430 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
370 divided by 131 is 2 with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 361809.84732
Subtracting 262 from 370 leaves us 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.

Let's proceed to step 14:
When dividing 1080 by 131, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 361809.847328
The remainder is 32 after subtracting 1048 from 1080.
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 15:
131 can be fit into 320 2 times, resulting in a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 361809.8473282
If we take 262 away from 320, we end up with 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 16:
131 goes into 580 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 361809.84732824
If we subtract 524 from 580, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 361809.84732824 with a remainder of 5.6e-08.
