We're dividing 80981825 by 424 
The aim is to understand the frequency of 424 in 80981825.

Moving on to step 1:
8 divided by 424 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 424

Moving on to step 2:
424 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 424

Let's proceed to step 3:
If we divide 809 by 424, we get 1 and a remainder of 385.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 385 after subtracting 424 from 809.
Fetch the next digit (8) from the dividend, attach it to 385 and continue: 3858 / 424

Moving on to step 4:
If we divide 3858 by 424, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 3816 from 3858 to get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 424

Moving on to step 5:
424 goes into 421 0 times with a remainder of 421.
Write down 0 as next digit of the result. 
Result so far: 190.0
The remainder is 421 after subtracting 0 from 421.
Grab the next digit (8) from the dividend, add it to 421, then carry on: 4218 / 424

Moving on to step 6:
424 can be fit into 4218 9 times, resulting in a remainder of 402.
Put 9 as the next digit of the answer. 
Result so far: 1909.0
Deduct 3816 from 4218 and we're left with 402.
Grab the next digit (2) from the dividend, add it to 402, then carry on: 4022 / 424

Going ahead to step 7:
The number 424 fits into 4022 9 times, leaving a remainder of 206.
Use 9 as the next digit of our solution. 
Result so far: 19099.0
Subtract 3816 from 4022 to get 206.
Grab the next digit (5) from the dividend, add it to 206, then carry on: 2065 / 424

Going ahead to step 8:
424 goes into 2065 4 times with a remainder of 369.
Put 4 as the next digit of the answer. 
Result so far: 190994.0
If we subtract 1696 from 2065, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
424 goes into 3690 8 times with a remainder of 298.
The next digit of our result is 8. 
Result so far: 190994.8
If we subtract 3392 from 3690, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 10:
The number 424 fits into 2980 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 190994.87
If we take 2968 away from 2980, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
The number 424 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 190994.87
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
If we divide 1200 by 424, we get 2 and a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 190994.8702
Deduct 848 from 1200 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 13:
If we divide 3520 by 424, we get 8 and a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 190994.87028
The remainder is 128 after subtracting 3392 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 14:
424 can be fit into 1280 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 190994.870283
Subtracting 1272 from 1280 leaves us 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.

Going ahead to step 15:
80 divided by 424 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 190994.870283
Deduct 0 from 80 and we're left 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.

Going ahead to step 16:
424 goes into 800 1 times with a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 190994.87028301
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.

The quotient of the division is 190994.87028301, and the remainder is 3.76e-07.
