19962420 ÷ 219 
The aim is to understand the frequency of 219 in 19962420.

Advancing to step 1:
If we divide 1 by 219, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 219

Step 2:
219 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 219

Moving on to step 3:
219 goes into 199 0 times with a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 199 to get 199.
Bring next digit (6) of the dividend behind the 199 and repeat the process: 1996 / 219

Step 4:
219 can be fit into 1996 9 times, resulting in a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 1971 from 1996, we get 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 219

Advancing to step 5:
219 goes into 252 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 219 from 252 leaves us with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 219

Going ahead to step 6:
When dividing 334 by 219, we get 1 with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 911.0
Subtract 219 from 334 to get 115.
Bring next digit (2) of the dividend behind the 115 and repeat the process: 1152 / 219

Going ahead to step 7:
219 can be fit into 1152 5 times, resulting in a remainder of 57.
The number 5 becomes the next digit in our result. 
Result so far: 9115.0
The remainder is 57 after subtracting 1095 from 1152.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 219

Step 8:
219 goes into 570 2 times with a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 91152.0
The remainder is 132 after subtracting 438 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 9:
The number 219 fits into 1320 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 91152.6
Deduct 1314 from 1320 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 219 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 91152.6
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 219, we get 2 with a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 91152.602
Subtract 438 from 600 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 12:
219 can be fit into 1620 7 times, resulting in a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 91152.6027
Subtracting 1533 from 1620 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
If we divide 870 by 219, we get 3 and a remainder of 213.
The next digit of our result is 3. 
Result so far: 91152.60273
If we take 657 away from 870, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 14:
219 goes into 2130 9 times with a remainder of 159.
The next digit of our result is 9. 
Result so far: 91152.602739
If we take 1971 away from 2130, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 15:
When dividing 1590 by 219, we get 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 91152.6027397
If we subtract 1533 from 1590, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 16:
When dividing 570 by 219, we get 2 with a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 91152.60273972
Deduct 438 from 570 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

After the division, we end up with 91152.60273972 and a remainder of 1.32e-07.
