16004778 divided by 215 
The aim is to understand the frequency of 215 in 16004778.

Step 1:
The number 215 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 215

On to step 2:
16 divided by 215 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 215

Advancing to step 3:
If we divide 160 by 215, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 160 after subtracting 0 from 160.
Fetch the next digit (0) from the dividend, attach it to 160 and continue: 1600 / 215

Going ahead to step 4:
215 can be fit into 1600 7 times, resulting in a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 1505 from 1600 and we're left with 95.
Take the next digit (4) from the dividend and append it to 95, then repeat: 954 / 215

Let's proceed to step 5:
215 can be fit into 954 4 times, resulting in a remainder of 94.
The next digit of our result is 4. 
Result so far: 74.0
Subtracting 860 from 954 leaves us with 94.
Include the next digit (7) from the dividend after 94, then repeat: 947 / 215

Moving on to step 6:
The number 215 fits into 947 4 times, leaving a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 744.0
If we subtract 860 from 947, we get 87.
Take the next digit (7) from the dividend and append it to 87, then repeat: 877 / 215

Going ahead to step 7:
When dividing 877 by 215, we get 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 7444.0
If we take 860 away from 877, we end up with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 215

On to step 8:
The number 215 fits into 178 0 times, leaving a remainder of 178.
Put 0 as the next digit of the answer. 
Result so far: 74440.0
If we take 0 away from 178, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 9:
215 can be fit into 1780 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 74440.8
The remainder is 60 after subtracting 1720 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 215, we get 2 with a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 74440.82
Subtracting 430 from 600 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
215 can be fit into 1700 7 times, resulting in a remainder of 195.
Record the quotient 7 as the next digit in the result. 
Result so far: 74440.827
Subtracting 1505 from 1700 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 12:
When dividing 1950 by 215, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 74440.8279
If we take 1935 away from 1950, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
215 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 74440.8279
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 14:
If we divide 1500 by 215, we get 6 and a remainder of 210.
Put 6 as the next digit of the answer. 
Result so far: 74440.827906
Subtract 1290 from 1500 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 15:
2100 divided by 215 is 9 with a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 74440.8279069
The remainder is 165 after subtracting 1935 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 16:
If we divide 1650 by 215, we get 7 and a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 74440.82790697
Subtract 1505 from 1650 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

After the division, we end up with 74440.82790697 and a remainder of 1.45e-07.
