12261392 divided by 279 
The aim is to understand the frequency of 279 in 12261392.

Going ahead to step 1:
279 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 279

On to step 2:
If we divide 12 by 279, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 279

On to step 3:
If we divide 122 by 279, we get 0 and a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Include the next digit (6) from the dividend after 122, then repeat: 1226 / 279

On to step 4:
The number 279 fits into 1226 4 times, leaving a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 1116 from 1226 leaves us with 110.
Fetch the next digit (1) from the dividend, attach it to 110 and continue: 1101 / 279

Moving on to step 5:
279 goes into 1101 3 times with a remainder of 264.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 837 from 1101 leaves us with 264.
Take the next digit (3) from the dividend and append it to 264, then repeat: 2643 / 279

Step 6:
If we divide 2643 by 279, we get 9 and a remainder of 132.
Record the quotient 9 as the next digit in the result. 
Result so far: 439.0
If we take 2511 away from 2643, we end up with 132.
Grab the next digit (9) from the dividend, add it to 132, then carry on: 1329 / 279

Advancing to step 7:
The number 279 fits into 1329 4 times, leaving a remainder of 213.
Use 4 as the next digit of our solution. 
Result so far: 4394.0
If we subtract 1116 from 1329, we get 213.
Bring next digit (2) of the dividend behind the 213 and repeat the process: 2132 / 279

Step 8:
The number 279 fits into 2132 7 times, leaving a remainder of 179.
The next digit of our result is 7. 
Result so far: 43947.0
If we take 1953 away from 2132, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 9:
279 can be fit into 1790 6 times, resulting in a remainder of 116.
Write down 6 as next digit of the result. 
Result so far: 43947.6
Subtract 1674 from 1790 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
1160 divided by 279 is 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 43947.64
Deduct 1116 from 1160 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
When dividing 440 by 279, we get 1 with a remainder of 161.
Use 1 as the next digit of our solution. 
Result so far: 43947.641
The remainder is 161 after subtracting 279 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 12:
1610 divided by 279 is 5 with a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 43947.6415
Subtract 1395 from 1610 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 13:
2150 divided by 279 is 7 with a remainder of 197.
Use 7 as the next digit of our solution. 
Result so far: 43947.64157
The remainder is 197 after subtracting 1953 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 14:
The number 279 fits into 1970 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 43947.641577
Subtracting 1953 from 1970 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 43947.641577, with a leftover of 1.7e-06.
