Let's divide 85020590 by 358
The aim is to understand the frequency of 358 in 85020590.

Step 1:
When dividing 8 by 358, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 358

Step 2:
The number 358 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 358

On to step 3:
When dividing 850 by 358, we get 2 with a remainder of 134.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 716 from 850, we get 134.
Take the next digit (2) from the dividend and append it to 134, then repeat: 1342 / 358

Advancing to step 4:
When dividing 1342 by 358, we get 3 with a remainder of 268.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 1074 from 1342, we get 268.
Bring next digit (0) of the dividend behind the 268 and repeat the process: 2680 / 358

Moving on to step 5:
358 goes into 2680 7 times with a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
Deduct 2506 from 2680 and we're left with 174.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 358

Let's proceed to step 6:
358 can be fit into 1745 4 times, resulting in a remainder of 313.
The number 4 becomes the next digit in our result. 
Result so far: 2374.0
If we take 1432 away from 1745, we end up with 313.
Grab the next digit (9) from the dividend, add it to 313, then carry on: 3139 / 358

Advancing to step 7:
When dividing 3139 by 358, we get 8 with a remainder of 275.
Write down 8 as next digit of the result. 
Result so far: 23748.0
If we subtract 2864 from 3139, we get 275.
Include the next digit (0) from the dividend after 275, then repeat: 2750 / 358

On to step 8:
The number 358 fits into 2750 7 times, leaving a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 237487.0
Deduct 2506 from 2750 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
The number 358 fits into 2440 6 times, leaving a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 237487.6
If we subtract 2148 from 2440, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 10:
The number 358 fits into 2920 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 237487.68
The remainder is 56 after subtracting 2864 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
358 can be fit into 560 1 times, resulting in a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 237487.681
The remainder is 202 after subtracting 358 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 12:
The number 358 fits into 2020 5 times, leaving a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 237487.6815
The remainder is 230 after subtracting 1790 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 13:
If we divide 2300 by 358, we get 6 and a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 237487.68156
The remainder is 152 after subtracting 2148 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 14:
358 goes into 1520 4 times with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 237487.681564
Subtract 1432 from 1520 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 15:
The number 358 fits into 880 2 times, leaving a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 237487.6815642
Deduct 716 from 880 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 16:
358 can be fit into 1640 4 times, resulting in a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 237487.68156424
If we subtract 1432 from 1640, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 237487.68156424 and a remainder of 2.08e-07.
