We divide 43213880 by 548
The aim is to understand the frequency of 548 in 43213880.

Going ahead to step 1:
548 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 548

On to step 2:
43 divided by 548 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 548

Advancing to step 3:
When dividing 432 by 548, we get 0 with a remainder of 432.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 432, we end up with 432.
Take the next digit (1) from the dividend and append it to 432, then repeat: 4321 / 548

Let's proceed to step 4:
548 can be fit into 4321 7 times, resulting in a remainder of 485.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 3836 from 4321 to get 485.
Include the next digit (3) from the dividend after 485, then repeat: 4853 / 548

Advancing to step 5:
548 goes into 4853 8 times with a remainder of 469.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtract 4384 from 4853 to get 469.
Fetch the next digit (8) from the dividend, attach it to 469 and continue: 4698 / 548

Moving on to step 6:
If we divide 4698 by 548, we get 8 and a remainder of 314.
Record the quotient 8 as the next digit in the result. 
Result so far: 788.0
The remainder is 314 after subtracting 4384 from 4698.
Append the next digit (8) from the dividend to 314 and continue with: 3148 / 548

On to step 7:
If we divide 3148 by 548, we get 5 and a remainder of 408.
Write down 5 as next digit of the result. 
Result so far: 7885.0
Subtract 2740 from 3148 to get 408.
Bring next digit (0) of the dividend behind the 408 and repeat the process: 4080 / 548

On to step 8:
548 goes into 4080 7 times with a remainder of 244.
The number 7 becomes the next digit in our result. 
Result so far: 78857.0
If we take 3836 away from 4080, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 9:
548 goes into 2440 4 times with a remainder of 248.
Use 4 as the next digit of our solution. 
Result so far: 78857.4
Deduct 2192 from 2440 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
The number 548 fits into 2480 4 times, leaving a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 78857.44
If we take 2192 away from 2480, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

After the division, we end up with 78857.44 and a remainder of 0.288.
