68460065 ÷ 558 
The aim is to understand the frequency of 558 in 68460065.

Step 1:
558 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 558

Advancing to step 2:
68 divided by 558 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 558

Let's proceed to step 3:
684 divided by 558 is 1 with a remainder of 126.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 558 from 684, we get 126.
Append the next digit (6) from the dividend to 126 and continue with: 1266 / 558

Moving on to step 4:
558 can be fit into 1266 2 times, resulting in a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1116 from 1266 leaves us with 150.
Take the next digit (0) from the dividend and append it to 150, then repeat: 1500 / 558

Advancing to step 5:
If we divide 1500 by 558, we get 2 and a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 1116 from 1500, we get 384.
Fetch the next digit (0) from the dividend, attach it to 384 and continue: 3840 / 558

Let's proceed to step 6:
558 can be fit into 3840 6 times, resulting in a remainder of 492.
Use 6 as the next digit of our solution. 
Result so far: 1226.0
Deduct 3348 from 3840 and we're left with 492.
Append the next digit (6) from the dividend to 492 and continue with: 4926 / 558

Let's proceed to step 7:
4926 divided by 558 is 8 with a remainder of 462.
The number 8 becomes the next digit in our result. 
Result so far: 12268.0
Deduct 4464 from 4926 and we're left with 462.
Include the next digit (5) from the dividend after 462, then repeat: 4625 / 558

On to step 8:
558 goes into 4625 8 times with a remainder of 161.
Put 8 as the next digit of the answer. 
Result so far: 122688.0
Subtract 4464 from 4625 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 9:
1610 divided by 558 is 2 with a remainder of 494.
Use 2 as the next digit of our solution. 
Result so far: 122688.2
If we take 1116 away from 1610, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 10:
If we divide 4940 by 558, we get 8 and a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 122688.28
If we take 4464 away from 4940, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 11:
558 can be fit into 4760 8 times, resulting in a remainder of 296.
Use 8 as the next digit of our solution. 
Result so far: 122688.288
Subtracting 4464 from 4760 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 122688.288, with a leftover of 0.0296.
