58308731 ÷ 217 
The aim is to understand the frequency of 217 in 58308731.

Moving on to step 1:
The number 217 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 217

Moving on to step 2:
When dividing 58 by 217, we get 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 217

Let's proceed to step 3:
217 can be fit into 583 2 times, resulting in a remainder of 149.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 434 from 583 leaves us with 149.
Append the next digit (0) from the dividend to 149 and continue with: 1490 / 217

On to step 4:
1490 divided by 217 is 6 with a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 1302 away from 1490, we end up with 188.
Fetch the next digit (8) from the dividend, attach it to 188 and continue: 1888 / 217

Let's proceed to step 5:
217 can be fit into 1888 8 times, resulting in a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
The remainder is 152 after subtracting 1736 from 1888.
Grab the next digit (7) from the dividend, add it to 152, then carry on: 1527 / 217

Going ahead to step 6:
217 can be fit into 1527 7 times, resulting in a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 2687.0
The remainder is 8 after subtracting 1519 from 1527.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 217

Going ahead to step 7:
If we divide 83 by 217, we get 0 and a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 26870.0
If we take 0 away from 83, we end up with 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 217

Let's proceed to step 8:
217 goes into 831 3 times with a remainder of 180.
Use 3 as the next digit of our solution. 
Result so far: 268703.0
The remainder is 180 after subtracting 651 from 831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 9:
1800 divided by 217 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 268703.8
If we subtract 1736 from 1800, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
217 goes into 640 2 times with a remainder of 206.
The number 2 becomes the next digit in our result. 
Result so far: 268703.82
Subtracting 434 from 640 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 11:
2060 divided by 217 is 9 with a remainder of 107.
The next digit of our result is 9. 
Result so far: 268703.829
The remainder is 107 after subtracting 1953 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 12:
217 goes into 1070 4 times with a remainder of 202.
The number 4 becomes the next digit in our result. 
Result so far: 268703.8294
Subtract 868 from 1070 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 13:
2020 divided by 217 is 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 268703.82949
The remainder is 67 after subtracting 1953 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 14:
217 goes into 670 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 268703.829493
Subtracting 651 from 670 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 15:
When dividing 190 by 217, we get 0 with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 268703.829493
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 16:
If we divide 1900 by 217, we get 8 and a remainder of 164.
The next digit of our result is 8. 
Result so far: 268703.82949308
The remainder is 164 after subtracting 1736 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final outcome is 268703.82949308, with a leftover of 1.64e-07.
