600458 ÷ 70 
The aim is to understand the frequency of 70 in 600458.

Step 1:
70 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 70

On to step 2:
If we divide 60 by 70, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 70

Going ahead to step 3:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 560 from 600 and we're left with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 70

Let's proceed to step 4:
70 goes into 404 5 times with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 350 from 404 leaves us with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 70

Moving on to step 5:
When dividing 545 by 70, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 857.0
Deduct 490 from 545 and we're left with 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 70

Let's proceed to step 6:
If we divide 558 by 70, we get 7 and a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 8577.0
Subtract 490 from 558 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
70 goes into 680 9 times with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 8577.9
The remainder is 50 after subtracting 630 from 680.
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 8:
If we divide 500 by 70, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 8577.97
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 8577.971
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 8577.9714
If we subtract 280 from 300, we get 20.
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 11:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 8577.97142
Subtracting 140 from 200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8577.971428
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
400 divided by 70 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8577.9714285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
500 divided by 70 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 8577.97142857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 8577.97142857 with a balance of 1e-08.
