We look at the division of 15683979 by 276 
The aim is to understand the frequency of 276 in 15683979.

Going ahead to step 1:
276 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 276

Moving on to step 2:
The number 276 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 276

Step 3:
276 can be fit into 156 0 times, resulting in a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 156, we get 156.
Include the next digit (8) from the dividend after 156, then repeat: 1568 / 276

Let's proceed to step 4:
1568 divided by 276 is 5 with a remainder of 188.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 1380 from 1568 leaves us with 188.
Fetch the next digit (3) from the dividend, attach it to 188 and continue: 1883 / 276

Going ahead to step 5:
1883 divided by 276 is 6 with a remainder of 227.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we subtract 1656 from 1883, we get 227.
Grab the next digit (9) from the dividend, add it to 227, then carry on: 2279 / 276

Going ahead to step 6:
The number 276 fits into 2279 8 times, leaving a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 568.0
Subtracting 2208 from 2279 leaves us with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 276

Let's proceed to step 7:
276 goes into 717 2 times with a remainder of 165.
Use 2 as the next digit of our solution. 
Result so far: 5682.0
Subtracting 552 from 717 leaves us with 165.
Append the next digit (9) from the dividend to 165 and continue with: 1659 / 276

Advancing to step 8:
The number 276 fits into 1659 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 56826.0
Deduct 1656 from 1659 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
276 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 56826.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
300 divided by 276 is 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 56826.01
Subtracting 276 from 300 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
When dividing 240 by 276, we get 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 56826.01
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 12:
When dividing 2400 by 276, we get 8 with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 56826.0108
The remainder is 192 after subtracting 2208 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 13:
If we divide 1920 by 276, we get 6 and a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 56826.01086
If we subtract 1656 from 1920, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 14:
276 goes into 2640 9 times with a remainder of 156.
Put 9 as the next digit of the answer. 
Result so far: 56826.010869
If we subtract 2484 from 2640, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 15:
276 goes into 1560 5 times with a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 56826.0108695
Subtract 1380 from 1560 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
1800 divided by 276 is 6 with a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 56826.01086956
If we take 1656 away from 1800, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 56826.01086956 and a remainder of 1.44e-07.
