Let's divide 7987558 by 217
The aim is to understand the frequency of 217 in 7987558.

Going ahead to step 1:
217 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 217

Let's proceed to step 2:
217 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 217

Let's proceed to step 3:
798 divided by 217 is 3 with a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 651 away from 798, we end up with 147.
Include the next digit (7) from the dividend after 147, then repeat: 1477 / 217

Advancing to step 4:
1477 divided by 217 is 6 with a remainder of 175.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 1302 from 1477 to get 175.
Include the next digit (5) from the dividend after 175, then repeat: 1755 / 217

Let's proceed to step 5:
217 goes into 1755 8 times with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 368.0
Subtract 1736 from 1755 to get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 217

Moving on to step 6:
195 divided by 217 is 0 with a remainder of 195.
Use 0 as the next digit of our solution. 
Result so far: 3680.0
Deduct 0 from 195 and we're left with 195.
Include the next digit (8) from the dividend after 195, then repeat: 1958 / 217

Step 7:
When dividing 1958 by 217, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 36809.0
Deduct 1953 from 1958 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
217 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 36809.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
217 goes into 500 2 times with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 36809.02
The remainder is 66 after subtracting 434 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
The number 217 fits into 660 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 36809.023
If we take 651 away from 660, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
90 divided by 217 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 36809.023
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
The number 217 fits into 900 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 36809.02304
If we subtract 868 from 900, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
If we divide 320 by 217, we get 1 and a remainder of 103.
Put 1 as the next digit of the answer. 
Result so far: 36809.023041
If we subtract 217 from 320, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 14:
If we divide 1030 by 217, we get 4 and a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 36809.0230414
Subtract 868 from 1030 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.

Moving on to step 15:
217 can be fit into 1620 7 times, resulting in a remainder of 101.
The next digit of our result is 7. 
Result so far: 36809.02304147
If we take 1519 away from 1620, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The quotient of the division is 36809.02304147, and the remainder is 1.01e-07.
