We look at the division of 28816674 by 548 
The aim is to understand the frequency of 548 in 28816674.

Step 1:
The number 548 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 548

On to step 2:
When dividing 28 by 548, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 548

On to step 3:
If we divide 288 by 548, we get 0 and a remainder of 288.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 288, we end up with 288.
Bring next digit (1) of the dividend behind the 288 and repeat the process: 2881 / 548

Let's proceed to step 4:
2881 divided by 548 is 5 with a remainder of 141.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 2740 from 2881 leaves us with 141.
Include the next digit (6) from the dividend after 141, then repeat: 1416 / 548

Going ahead to step 5:
1416 divided by 548 is 2 with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 1096 away from 1416, we end up with 320.
Grab the next digit (6) from the dividend, add it to 320, then carry on: 3206 / 548

Step 6:
548 can be fit into 3206 5 times, resulting in a remainder of 466.
Put 5 as the next digit of the answer. 
Result so far: 525.0
Subtract 2740 from 3206 to get 466.
Grab the next digit (7) from the dividend, add it to 466, then carry on: 4667 / 548

Going ahead to step 7:
If we divide 4667 by 548, we get 8 and a remainder of 283.
Write down 8 as next digit of the result. 
Result so far: 5258.0
Subtract 4384 from 4667 to get 283.
Fetch the next digit (4) from the dividend, attach it to 283 and continue: 2834 / 548

Moving on to step 8:
2834 divided by 548 is 5 with a remainder of 94.
Use 5 as the next digit of our solution. 
Result so far: 52585.0
Deduct 2740 from 2834 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
When dividing 940 by 548, we get 1 with a remainder of 392.
The next digit of our result is 1. 
Result so far: 52585.1
Subtract 548 from 940 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
The number 548 fits into 3920 7 times, leaving a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 52585.17
Deduct 3836 from 3920 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
If we divide 840 by 548, we get 1 and a remainder of 292.
Record the quotient 1 as the next digit in the result. 
Result so far: 52585.171
The remainder is 292 after subtracting 548 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 12:
The number 548 fits into 2920 5 times, leaving a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 52585.1715
Subtracting 2740 from 2920 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
When dividing 1800 by 548, we get 3 with a remainder of 156.
Write down 3 as next digit of the result. 
Result so far: 52585.17153
If we take 1644 away from 1800, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 14:
The number 548 fits into 1560 2 times, leaving a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 52585.171532
If we take 1096 away from 1560, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 15:
The number 548 fits into 4640 8 times, leaving a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 52585.1715328
Subtracting 4384 from 4640 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
If we divide 2560 by 548, we get 4 and a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 52585.17153284
If we subtract 2192 from 2560, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 52585.17153284 and a remainder of 3.68e-07.
