19718913 ÷ 428 
The aim is to understand the frequency of 428 in 19718913.

Step 1:
428 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 428

Advancing to step 2:
19 divided by 428 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 428

Moving on to step 3:
When dividing 197 by 428, we get 0 with a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 197 and we're left with 197.
Include the next digit (1) from the dividend after 197, then repeat: 1971 / 428

On to step 4:
If we divide 1971 by 428, we get 4 and a remainder of 259.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1712 from 1971 to get 259.
Include the next digit (8) from the dividend after 259, then repeat: 2598 / 428

Advancing to step 5:
2598 divided by 428 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 2568 away from 2598, we end up with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 428

Moving on to step 6:
428 can be fit into 309 0 times, resulting in a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
Subtract 0 from 309 to get 309.
Fetch the next digit (1) from the dividend, attach it to 309 and continue: 3091 / 428

On to step 7:
The number 428 fits into 3091 7 times, leaving a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 4607.0
If we subtract 2996 from 3091, we get 95.
Take the next digit (3) from the dividend and append it to 95, then repeat: 953 / 428

On to step 8:
If we divide 953 by 428, we get 2 and a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 46072.0
Subtract 856 from 953 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
970 divided by 428 is 2 with a remainder of 114.
The next digit of our result is 2. 
Result so far: 46072.2
If we take 856 away from 970, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 10:
428 goes into 1140 2 times with a remainder of 284.
Record the quotient 2 as the next digit in the result. 
Result so far: 46072.22
Deduct 856 from 1140 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 46072.22 with a balance of 0.284.
