72463339 ÷ 278 
The aim is to understand the frequency of 278 in 72463339.

Step 1:
If we divide 7 by 278, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 278

On to step 2:
278 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (4) from the dividend after 72, then repeat: 724 / 278

Advancing to step 3:
When dividing 724 by 278, we get 2 with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 168 after subtracting 556 from 724.
Grab the next digit (6) from the dividend, add it to 168, then carry on: 1686 / 278

Going ahead to step 4:
278 can be fit into 1686 6 times, resulting in a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 1668 from 1686 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 278

On to step 5:
The number 278 fits into 183 0 times, leaving a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
If we take 0 away from 183, we end up with 183.
Bring next digit (3) of the dividend behind the 183 and repeat the process: 1833 / 278

Step 6:
1833 divided by 278 is 6 with a remainder of 165.
The next digit of our result is 6. 
Result so far: 2606.0
Subtract 1668 from 1833 to get 165.
Take the next digit (3) from the dividend and append it to 165, then repeat: 1653 / 278

Moving on to step 7:
The number 278 fits into 1653 5 times, leaving a remainder of 263.
Use 5 as the next digit of our solution. 
Result so far: 26065.0
The remainder is 263 after subtracting 1390 from 1653.
Append the next digit (9) from the dividend to 263 and continue with: 2639 / 278

Going ahead to step 8:
278 can be fit into 2639 9 times, resulting in a remainder of 137.
Use 9 as the next digit of our solution. 
Result so far: 260659.0
If we subtract 2502 from 2639, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
1370 divided by 278 is 4 with a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 260659.4
The remainder is 258 after subtracting 1112 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 10:
When dividing 2580 by 278, we get 9 with a remainder of 78.
The next digit of our result is 9. 
Result so far: 260659.49
Deduct 2502 from 2580 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
780 divided by 278 is 2 with a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 260659.492
If we subtract 556 from 780, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
2240 divided by 278 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 260659.4928
If we take 2224 away from 2240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
278 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 260659.4928
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
When dividing 1600 by 278, we get 5 with a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 260659.492805
The remainder is 210 after subtracting 1390 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 15:
278 can be fit into 2100 7 times, resulting in a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 260659.4928057
Subtract 1946 from 2100 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 16:
1540 divided by 278 is 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 260659.49280575
If we take 1390 away from 1540, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 260659.49280575, with a leftover of 1.5e-07.
