We look at the division of 42389068 by 658 
The aim is to understand the frequency of 658 in 42389068.

Let's proceed to step 1:
658 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 658

Advancing to step 2:
658 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 658

Step 3:
If we divide 423 by 658, we get 0 and a remainder of 423.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Fetch the next digit (8) from the dividend, attach it to 423 and continue: 4238 / 658

Going ahead to step 4:
4238 divided by 658 is 6 with a remainder of 290.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 3948 from 4238 and we're left with 290.
Grab the next digit (9) from the dividend, add it to 290, then carry on: 2909 / 658

On to step 5:
658 can be fit into 2909 4 times, resulting in a remainder of 277.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 2632 from 2909 leaves us with 277.
Append the next digit (0) from the dividend to 277 and continue with: 2770 / 658

On to step 6:
If we divide 2770 by 658, we get 4 and a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 644.0
The remainder is 138 after subtracting 2632 from 2770.
Bring next digit (6) of the dividend behind the 138 and repeat the process: 1386 / 658

Advancing to step 7:
658 can be fit into 1386 2 times, resulting in a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 6442.0
The remainder is 70 after subtracting 1316 from 1386.
Append the next digit (8) from the dividend to 70 and continue with: 708 / 658

Let's proceed to step 8:
708 divided by 658 is 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 64421.0
Deduct 658 from 708 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
658 goes into 500 0 times with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 64421.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
When dividing 5000 by 658, we get 7 with a remainder of 394.
The number 7 becomes the next digit in our result. 
Result so far: 64421.07
Deduct 4606 from 5000 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 11:
If we divide 3940 by 658, we get 5 and a remainder of 650.
Use 5 as the next digit of our solution. 
Result so far: 64421.075
The remainder is 650 after subtracting 3290 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 12:
6500 divided by 658 is 9 with a remainder of 578.
Record the quotient 9 as the next digit in the result. 
Result so far: 64421.0759
If we take 5922 away from 6500, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 13:
The number 658 fits into 5780 8 times, leaving a remainder of 516.
The number 8 becomes the next digit in our result. 
Result so far: 64421.07598
If we take 5264 away from 5780, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 14:
The number 658 fits into 5160 7 times, leaving a remainder of 554.
The next digit of our result is 7. 
Result so far: 64421.075987
Deduct 4606 from 5160 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 15:
658 can be fit into 5540 8 times, resulting in a remainder of 276.
The next digit of our result is 8. 
Result so far: 64421.0759878
If we take 5264 away from 5540, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 16:
If we divide 2760 by 658, we get 4 and a remainder of 128.
The next digit of our result is 4. 
Result so far: 64421.07598784
If we take 2632 away from 2760, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 64421.07598784 with a balance of 1.28e-07.
