38810851 divided by 131 
The aim is to understand the frequency of 131 in 38810851.

Moving on to step 1:
When dividing 3 by 131, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 131

Let's proceed to step 2:
38 divided by 131 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 131

Step 3:
131 goes into 388 2 times with a remainder of 126.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 262 from 388, we get 126.
Append the next digit (1) from the dividend to 126 and continue with: 1261 / 131

Moving on to step 4:
131 can be fit into 1261 9 times, resulting in a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 1179 from 1261, we get 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 131

Step 5:
When dividing 820 by 131, we get 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 296.0
Deduct 786 from 820 and we're left with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 131

Advancing to step 6:
If we divide 348 by 131, we get 2 and a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 2962.0
Subtracting 262 from 348 leaves us with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 131

Step 7:
131 goes into 865 6 times with a remainder of 79.
Put 6 as the next digit of the answer. 
Result so far: 29626.0
If we subtract 786 from 865, we get 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 131

Let's proceed to step 8:
The number 131 fits into 791 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 296266.0
The remainder is 5 after subtracting 786 from 791.
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 9:
If we divide 50 by 131, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 296266.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
The number 131 fits into 500 3 times, leaving a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 296266.03
Subtract 393 from 500 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 11:
If we divide 1070 by 131, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 296266.038
Subtract 1048 from 1070 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
When dividing 220 by 131, we get 1 with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 296266.0381
Deduct 131 from 220 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 13:
890 divided by 131 is 6 with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 296266.03816
If we subtract 786 from 890, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 14:
The number 131 fits into 1040 7 times, leaving a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 296266.038167
The remainder is 123 after subtracting 917 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 15:
131 goes into 1230 9 times with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 296266.0381679
Subtracting 1179 from 1230 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 16:
131 goes into 510 3 times with a remainder of 117.
Write down 3 as next digit of the result. 
Result so far: 296266.03816793
Subtract 393 from 510 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

In conclusion, the division gives 296266.03816793 with a balance of 1.17e-07.
