Let's divide 27998874 by 424
The aim is to understand the frequency of 424 in 27998874.

On to step 1:
2 divided by 424 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 424

Let's proceed to step 2:
27 divided by 424 is 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 424

Moving on to step 3:
424 goes into 279 0 times with a remainder of 279.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 279 after subtracting 0 from 279.
Grab the next digit (9) from the dividend, add it to 279, then carry on: 2799 / 424

Moving on to step 4:
The number 424 fits into 2799 6 times, leaving a remainder of 255.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 2544 away from 2799, we end up with 255.
Grab the next digit (8) from the dividend, add it to 255, then carry on: 2558 / 424

Advancing to step 5:
If we divide 2558 by 424, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 66.0
Deduct 2544 from 2558 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 424

Moving on to step 6:
The number 424 fits into 148 0 times, leaving a remainder of 148.
Use 0 as the next digit of our solution. 
Result so far: 660.0
Deduct 0 from 148 and we're left with 148.
Fetch the next digit (7) from the dividend, attach it to 148 and continue: 1487 / 424

Going ahead to step 7:
424 can be fit into 1487 3 times, resulting in a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 6603.0
Subtracting 1272 from 1487 leaves us with 215.
Include the next digit (4) from the dividend after 215, then repeat: 2154 / 424

Going ahead to step 8:
When dividing 2154 by 424, we get 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 66035.0
If we take 2120 away from 2154, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
The number 424 fits into 340 0 times, leaving a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 66035.0
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
If we divide 3400 by 424, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 66035.08
If we take 3392 away from 3400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
424 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 66035.08
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
424 goes into 800 1 times with a remainder of 376.
The number 1 becomes the next digit in our result. 
Result so far: 66035.0801
If we take 424 away from 800, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 13:
If we divide 3760 by 424, we get 8 and a remainder of 368.
The next digit of our result is 8. 
Result so far: 66035.08018
Deduct 3392 from 3760 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 14:
If we divide 3680 by 424, we get 8 and a remainder of 288.
The next digit of our result is 8. 
Result so far: 66035.080188
If we subtract 3392 from 3680, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

In conclusion, the division gives 66035.080188 with a balance of 2.88e-05.
