We look at the division of 44103640 by 278 
The aim is to understand the frequency of 278 in 44103640.

On to step 1:
4 divided by 278 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 278

On to step 2:
The number 278 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 278

Advancing to step 3:
If we divide 441 by 278, we get 1 and a remainder of 163.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 278 from 441 leaves us with 163.
Include the next digit (0) from the dividend after 163, then repeat: 1630 / 278

Let's proceed to step 4:
The number 278 fits into 1630 5 times, leaving a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 1390 from 1630 and we're left with 240.
Bring next digit (3) of the dividend behind the 240 and repeat the process: 2403 / 278

Going ahead to step 5:
If we divide 2403 by 278, we get 8 and a remainder of 179.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Deduct 2224 from 2403 and we're left with 179.
Fetch the next digit (6) from the dividend, attach it to 179 and continue: 1796 / 278

Going ahead to step 6:
When dividing 1796 by 278, we get 6 with a remainder of 128.
The next digit of our result is 6. 
Result so far: 1586.0
Subtract 1668 from 1796 to get 128.
Grab the next digit (4) from the dividend, add it to 128, then carry on: 1284 / 278

On to step 7:
If we divide 1284 by 278, we get 4 and a remainder of 172.
Record the quotient 4 as the next digit in the result. 
Result so far: 15864.0
If we take 1112 away from 1284, we end up with 172.
Bring next digit (0) of the dividend behind the 172 and repeat the process: 1720 / 278

On to step 8:
278 can be fit into 1720 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 158646.0
If we take 1668 away from 1720, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
If we divide 520 by 278, we get 1 and a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 158646.1
Subtracting 278 from 520 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 10:
When dividing 2420 by 278, we get 8 with a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 158646.18
If we subtract 2224 from 2420, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
1960 divided by 278 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 158646.187
Subtract 1946 from 1960 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
When dividing 140 by 278, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 158646.187
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
The number 278 fits into 1400 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 158646.18705
Subtracting 1390 from 1400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 278 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 158646.18705
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
The number 278 fits into 1000 3 times, leaving a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 158646.1870503
If we take 834 away from 1000, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 16:
If we divide 1660 by 278, we get 5 and a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 158646.18705035
The remainder is 270 after subtracting 1390 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final result is 158646.18705035 with a remainder of 2.7e-07.
