44553749 ÷ 131 
The aim is to understand the frequency of 131 in 44553749.

Let's proceed to step 1:
The number 131 fits into 4 0 times, leaving 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.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 131

Going ahead to step 2:
131 can be fit into 44 0 times, resulting in a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 131

On to step 3:
If we divide 445 by 131, we get 3 and a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 393 from 445 and we're left with 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 131

Going ahead to step 4:
When dividing 525 by 131, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 524 from 525, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 131

On to step 5:
If we divide 13 by 131, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 340.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 131

On to step 6:
If we divide 137 by 131, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 3401.0
If we take 131 away from 137, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 131

Advancing to step 7:
When dividing 64 by 131, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 34010.0
Subtract 0 from 64 to get 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 131

Moving on to step 8:
If we divide 649 by 131, we get 4 and a remainder of 125.
Record the quotient 4 as the next digit in the result. 
Result so far: 340104.0
Subtracting 524 from 649 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
131 goes into 1250 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 340104.9
Subtract 1179 from 1250 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
The number 131 fits into 710 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 340104.95
If we subtract 655 from 710, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
131 goes into 550 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 340104.954
Subtracting 524 from 550 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 131 is 1 with a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 340104.9541
If we subtract 131 from 260, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 13:
The number 131 fits into 1290 9 times, leaving a remainder of 111.
The next digit of our result is 9. 
Result so far: 340104.95419
Subtract 1179 from 1290 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 14:
If we divide 1110 by 131, we get 8 and a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 340104.954198
Deduct 1048 from 1110 and we're left 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.

On to step 15:
620 divided by 131 is 4 with a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 340104.9541984
Subtract 524 from 620 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
The number 131 fits into 960 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 340104.95419847
Deduct 917 from 960 and we're left 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.

After the division, we end up with 340104.95419847 and a remainder of 4.3e-08.
