15291609 divided by 267 
The aim is to understand the frequency of 267 in 15291609.

On to step 1:
267 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 267

Going ahead to step 2:
The number 267 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 267

On to step 3:
267 can be fit into 152 0 times, resulting in a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 152, we get 152.
Bring next digit (9) of the dividend behind the 152 and repeat the process: 1529 / 267

Step 4:
When dividing 1529 by 267, we get 5 with a remainder of 194.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 1335 from 1529 to get 194.
Append the next digit (1) from the dividend to 194 and continue with: 1941 / 267

Going ahead to step 5:
The number 267 fits into 1941 7 times, leaving a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Deduct 1869 from 1941 and we're left with 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 267

Let's proceed to step 6:
When dividing 726 by 267, we get 2 with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 572.0
If we take 534 away from 726, we end up with 192.
Fetch the next digit (0) from the dividend, attach it to 192 and continue: 1920 / 267

Step 7:
267 goes into 1920 7 times with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 5727.0
Deduct 1869 from 1920 and we're left with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 267

Let's proceed to step 8:
If we divide 519 by 267, we get 1 and a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 57271.0
Subtract 267 from 519 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 9:
267 can be fit into 2520 9 times, resulting in a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 57271.9
The remainder is 117 after subtracting 2403 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 10:
If we divide 1170 by 267, we get 4 and a remainder of 102.
The next digit of our result is 4. 
Result so far: 57271.94
Subtract 1068 from 1170 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 11:
267 goes into 1020 3 times with a remainder of 219.
The number 3 becomes the next digit in our result. 
Result so far: 57271.943
If we subtract 801 from 1020, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 12:
The number 267 fits into 2190 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 57271.9438
Subtracting 2136 from 2190 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
If we divide 540 by 267, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 57271.94382
The remainder is 6 after subtracting 534 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 267, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 57271.94382
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
The number 267 fits into 600 2 times, leaving a remainder of 66.
The next digit of our result is 2. 
Result so far: 57271.9438202
The remainder is 66 after subtracting 534 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 16:
267 can be fit into 660 2 times, resulting in a remainder of 126.
The next digit of our result is 2. 
Result so far: 57271.94382022
Subtract 534 from 660 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

In conclusion, the division gives 57271.94382022 with a balance of 1.26e-07.
