We look at the division of 70085958 by 958 
The aim is to understand the frequency of 958 in 70085958.

Step 1:
If we divide 7 by 958, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 958

Going ahead to step 2:
The number 958 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 958

Let's proceed to step 3:
When dividing 700 by 958, we get 0 with a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 700 leaves us with 700.
Include the next digit (8) from the dividend after 700, then repeat: 7008 / 958

Going ahead to step 4:
If we divide 7008 by 958, we get 7 and a remainder of 302.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 302 after subtracting 6706 from 7008.
Fetch the next digit (5) from the dividend, attach it to 302 and continue: 3025 / 958

On to step 5:
958 goes into 3025 3 times with a remainder of 151.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Deduct 2874 from 3025 and we're left with 151.
Take the next digit (9) from the dividend and append it to 151, then repeat: 1519 / 958

Advancing to step 6:
1519 divided by 958 is 1 with a remainder of 561.
The number 1 becomes the next digit in our result. 
Result so far: 731.0
If we take 958 away from 1519, we end up with 561.
Include the next digit (5) from the dividend after 561, then repeat: 5615 / 958

Step 7:
The number 958 fits into 5615 5 times, leaving a remainder of 825.
Put 5 as the next digit of the answer. 
Result so far: 7315.0
Subtracting 4790 from 5615 leaves us with 825.
Bring next digit (8) of the dividend behind the 825 and repeat the process: 8258 / 958

Step 8:
8258 divided by 958 is 8 with a remainder of 594.
The next digit of our result is 8. 
Result so far: 73158.0
Subtracting 7664 from 8258 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 9:
958 goes into 5940 6 times with a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 73158.6
If we subtract 5748 from 5940, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 10:
1920 divided by 958 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 73158.62
If we take 1916 away from 1920, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
958 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 73158.62
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
958 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 73158.62
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 73158.62 and a remainder of 0.004.
