58039155 ÷ 668 
The aim is to understand the frequency of 668 in 58039155.

Let's proceed to step 1:
When dividing 5 by 668, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 668

On to step 2:
If we divide 58 by 668, we get 0 and a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 668

Step 3:
If we divide 580 by 668, we get 0 and a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 580 leaves us with 580.
Append the next digit (3) from the dividend to 580 and continue with: 5803 / 668

Moving on to step 4:
The number 668 fits into 5803 8 times, leaving a remainder of 459.
The next digit of our result is 8. 
Result so far: 8.0
If we take 5344 away from 5803, we end up with 459.
Bring next digit (9) of the dividend behind the 459 and repeat the process: 4599 / 668

Advancing to step 5:
When dividing 4599 by 668, we get 6 with a remainder of 591.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 591 after subtracting 4008 from 4599.
Take the next digit (1) from the dividend and append it to 591, then repeat: 5911 / 668

Going ahead to step 6:
The number 668 fits into 5911 8 times, leaving a remainder of 567.
Record the quotient 8 as the next digit in the result. 
Result so far: 868.0
The remainder is 567 after subtracting 5344 from 5911.
Fetch the next digit (5) from the dividend, attach it to 567 and continue: 5675 / 668

Advancing to step 7:
The number 668 fits into 5675 8 times, leaving a remainder of 331.
The number 8 becomes the next digit in our result. 
Result so far: 8688.0
Deduct 5344 from 5675 and we're left with 331.
Fetch the next digit (5) from the dividend, attach it to 331 and continue: 3315 / 668

Advancing to step 8:
When dividing 3315 by 668, we get 4 with a remainder of 643.
Write down 4 as next digit of the result. 
Result so far: 86884.0
Subtracting 2672 from 3315 leaves us with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

On to step 9:
When dividing 6430 by 668, we get 9 with a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 86884.9
If we subtract 6012 from 6430, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 10:
668 can be fit into 4180 6 times, resulting in a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 86884.96
If we subtract 4008 from 4180, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
The number 668 fits into 1720 2 times, leaving a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 86884.962
Subtracting 1336 from 1720 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
When dividing 3840 by 668, we get 5 with a remainder of 500.
The next digit of our result is 5. 
Result so far: 86884.9625
The remainder is 500 after subtracting 3340 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
If we divide 5000 by 668, we get 7 and a remainder of 324.
The next digit of our result is 7. 
Result so far: 86884.96257
If we take 4676 away from 5000, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 14:
When dividing 3240 by 668, we get 4 with a remainder of 568.
Use 4 as the next digit of our solution. 
Result so far: 86884.962574
If we take 2672 away from 3240, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 15:
If we divide 5680 by 668, we get 8 and a remainder of 336.
Use 8 as the next digit of our solution. 
Result so far: 86884.9625748
Subtract 5344 from 5680 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 16:
668 can be fit into 3360 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 86884.96257485
If we take 3340 away from 3360, 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.

After the division, we end up with 86884.96257485 and a remainder of 2e-08.
