We divide 20716330 by 424
The aim is to understand the frequency of 424 in 20716330.

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
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 424

On to step 2:
424 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 424

On to step 3:
When dividing 207 by 424, we get 0 with a remainder of 207.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 207 to get 207.
Append the next digit (1) from the dividend to 207 and continue with: 2071 / 424

On to step 4:
424 goes into 2071 4 times with a remainder of 375.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1696 from 2071 to get 375.
Bring next digit (6) of the dividend behind the 375 and repeat the process: 3756 / 424

Let's proceed to step 5:
424 goes into 3756 8 times with a remainder of 364.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtracting 3392 from 3756 leaves us with 364.
Append the next digit (3) from the dividend to 364 and continue with: 3643 / 424

On to step 6:
424 goes into 3643 8 times with a remainder of 251.
Record the quotient 8 as the next digit in the result. 
Result so far: 488.0
Subtract 3392 from 3643 to get 251.
Bring next digit (3) of the dividend behind the 251 and repeat the process: 2513 / 424

Step 7:
When dividing 2513 by 424, we get 5 with a remainder of 393.
Use 5 as the next digit of our solution. 
Result so far: 4885.0
If we take 2120 away from 2513, we end up with 393.
Fetch the next digit (0) from the dividend, attach it to 393 and continue: 3930 / 424

Step 8:
424 goes into 3930 9 times with a remainder of 114.
The next digit of our result is 9. 
Result so far: 48859.0
Subtract 3816 from 3930 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 9:
The number 424 fits into 1140 2 times, leaving a remainder of 292.
The number 2 becomes the next digit in our result. 
Result so far: 48859.2
If we subtract 848 from 1140, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 10:
424 goes into 2920 6 times with a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 48859.26
The remainder is 376 after subtracting 2544 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 11:
424 can be fit into 3760 8 times, resulting in a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 48859.268
Subtract 3392 from 3760 to 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.

Moving on to step 12:
When dividing 3680 by 424, we get 8 with a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 48859.2688
Subtract 3392 from 3680 to 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.

The final result is 48859.2688 with a remainder of 0.00288.
