216429 ÷ 58 
The aim is to understand the frequency of 58 in 216429.

Going ahead to step 1:
If we divide 2 by 58, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 58

Moving on to step 2:
21 divided by 58 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 58

Advancing to step 3:
When dividing 216 by 58, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 174 from 216 and we're left with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 58

Let's proceed to step 4:
58 goes into 424 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 406 from 424 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 58

Going ahead to step 5:
58 goes into 182 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 373.0
Deduct 174 from 182 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 58

Let's proceed to step 6:
When dividing 89 by 58, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 3731.0
Subtracting 58 from 89 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
310 divided by 58 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 3731.5
The remainder is 20 after subtracting 290 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 58, we get 3 and a remainder of 26.
The next digit of our result is 3. 
Result so far: 3731.53
Deduct 174 from 200 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
The number 58 fits into 260 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 3731.534
If we take 232 away from 260, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
If we divide 280 by 58, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 3731.5344
The remainder is 48 after subtracting 232 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 3731.5344 with a remainder of 0.00048.
