We're dividing 7289361 by 217 
The aim is to understand the frequency of 217 in 7289361.

Let's proceed to step 1:
If we divide 7 by 217, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 217

Step 2:
217 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 217

Advancing to step 3:
The number 217 fits into 728 3 times, leaving a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 77 after subtracting 651 from 728.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 217

Step 4:
217 goes into 779 3 times with a remainder of 128.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 651 away from 779, we end up with 128.
Bring next digit (3) of the dividend behind the 128 and repeat the process: 1283 / 217

On to step 5:
1283 divided by 217 is 5 with a remainder of 198.
Write down 5 as next digit of the result. 
Result so far: 335.0
Deduct 1085 from 1283 and we're left with 198.
Take the next digit (6) from the dividend and append it to 198, then repeat: 1986 / 217

Going ahead to step 6:
1986 divided by 217 is 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 3359.0
Deduct 1953 from 1986 and we're left with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 217

Step 7:
331 divided by 217 is 1 with a remainder of 114.
The number 1 becomes the next digit in our result. 
Result so far: 33591.0
The remainder is 114 after subtracting 217 from 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 8:
217 goes into 1140 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 33591.5
Subtract 1085 from 1140 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
When dividing 550 by 217, we get 2 with a remainder of 116.
Record the quotient 2 as the next digit in the result. 
Result so far: 33591.52
Deduct 434 from 550 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
217 can be fit into 1160 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 33591.525
Subtract 1085 from 1160 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
750 divided by 217 is 3 with a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 33591.5253
Deduct 651 from 750 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 12:
217 goes into 990 4 times with a remainder of 122.
Put 4 as the next digit of the answer. 
Result so far: 33591.52534
Subtract 868 from 990 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 13:
If we divide 1220 by 217, we get 5 and a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 33591.525345
Subtract 1085 from 1220 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 14:
When dividing 1350 by 217, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 33591.5253456
The remainder is 48 after subtracting 1302 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 15:
The number 217 fits into 480 2 times, leaving a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 33591.52534562
The remainder is 46 after subtracting 434 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 33591.52534562 with a balance of 4.6e-08.
