Let's divide 43379878 by 281
The aim is to understand the frequency of 281 in 43379878.

Step 1:
281 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 281

Going ahead to step 2:
The number 281 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 281

Going ahead to step 3:
281 can be fit into 433 1 times, resulting in a remainder of 152.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 281 from 433 leaves us with 152.
Include the next digit (7) from the dividend after 152, then repeat: 1527 / 281

Step 4:
The number 281 fits into 1527 5 times, leaving a remainder of 122.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 122 after subtracting 1405 from 1527.
Bring next digit (9) of the dividend behind the 122 and repeat the process: 1229 / 281

Advancing to step 5:
281 goes into 1229 4 times with a remainder of 105.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we take 1124 away from 1229, we end up with 105.
Take the next digit (8) from the dividend and append it to 105, then repeat: 1058 / 281

On to step 6:
If we divide 1058 by 281, we get 3 and a remainder of 215.
Record the quotient 3 as the next digit in the result. 
Result so far: 1543.0
If we subtract 843 from 1058, we get 215.
Take the next digit (7) from the dividend and append it to 215, then repeat: 2157 / 281

Let's proceed to step 7:
2157 divided by 281 is 7 with a remainder of 190.
Record the quotient 7 as the next digit in the result. 
Result so far: 15437.0
Deduct 1967 from 2157 and we're left with 190.
Append the next digit (8) from the dividend to 190 and continue with: 1908 / 281

Going ahead to step 8:
281 goes into 1908 6 times with a remainder of 222.
Use 6 as the next digit of our solution. 
Result so far: 154376.0
Deduct 1686 from 1908 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 9:
When dividing 2220 by 281, we get 7 with a remainder of 253.
The number 7 becomes the next digit in our result. 
Result so far: 154376.7
Subtracting 1967 from 2220 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 10:
When dividing 2530 by 281, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 154376.79
If we subtract 2529 from 2530, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
10 divided by 281 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 154376.79
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
If we divide 100 by 281, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 154376.79
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.

The final result is 154376.79 with a remainder of 0.001.
