16345712 ÷ 558 
The aim is to understand the frequency of 558 in 16345712.

Advancing to step 1:
When dividing 1 by 558, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in 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 / 558

On to step 2:
16 divided by 558 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 558

Step 3:
163 divided by 558 is 0 with a remainder of 163.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 163, we end up with 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 558

Moving on to step 4:
If we divide 1634 by 558, we get 2 and a remainder of 518.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 518 after subtracting 1116 from 1634.
Take the next digit (5) from the dividend and append it to 518, then repeat: 5185 / 558

Advancing to step 5:
558 goes into 5185 9 times with a remainder of 163.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 5022 from 5185, we get 163.
Bring next digit (7) of the dividend behind the 163 and repeat the process: 1637 / 558

On to step 6:
558 goes into 1637 2 times with a remainder of 521.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtracting 1116 from 1637 leaves us with 521.
Include the next digit (1) from the dividend after 521, then repeat: 5211 / 558

Let's proceed to step 7:
When dividing 5211 by 558, we get 9 with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 2929.0
Subtracting 5022 from 5211 leaves us with 189.
Include the next digit (2) from the dividend after 189, then repeat: 1892 / 558

Advancing to step 8:
When dividing 1892 by 558, we get 3 with a remainder of 218.
Write down 3 as next digit of the result. 
Result so far: 29293.0
If we take 1674 away from 1892, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 9:
If we divide 2180 by 558, we get 3 and a remainder of 506.
The next digit of our result is 3. 
Result so far: 29293.3
If we subtract 1674 from 2180, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 10:
If we divide 5060 by 558, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 29293.39
Subtract 5022 from 5060 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
The number 558 fits into 380 0 times, leaving a remainder of 380.
The next digit of our result is 0. 
Result so far: 29293.39
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 12:
558 can be fit into 3800 6 times, resulting in a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 29293.3906
If we take 3348 away from 3800, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 13:
The number 558 fits into 4520 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 29293.39068
Subtract 4464 from 4520 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
560 divided by 558 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 29293.390681
If we subtract 558 from 560, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 15:
If we divide 20 by 558, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 29293.390681
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
If we divide 200 by 558, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 29293.390681
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 29293.390681 with a balance of 2e-07.
