9657577 divided by 858 
The aim is to understand the frequency of 858 in 9657577.

Step 1:
If we divide 9 by 858, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 858

Let's proceed to step 2:
858 can be fit into 96 0 times, resulting in a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Bring next digit (5) of the dividend behind the 96 and repeat the process: 965 / 858

Moving on to step 3:
858 goes into 965 1 times with a remainder of 107.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 107 after subtracting 858 from 965.
Grab the next digit (7) from the dividend, add it to 107, then carry on: 1077 / 858

Step 4:
When dividing 1077 by 858, we get 1 with a remainder of 219.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 219 after subtracting 858 from 1077.
Include the next digit (5) from the dividend after 219, then repeat: 2195 / 858

Going ahead to step 5:
2195 divided by 858 is 2 with a remainder of 479.
Write down 2 as next digit of the result. 
Result so far: 112.0
The remainder is 479 after subtracting 1716 from 2195.
Take the next digit (7) from the dividend and append it to 479, then repeat: 4797 / 858

Advancing to step 6:
The number 858 fits into 4797 5 times, leaving a remainder of 507.
The number 5 becomes the next digit in our result. 
Result so far: 1125.0
If we take 4290 away from 4797, we end up with 507.
Append the next digit (7) from the dividend to 507 and continue with: 5077 / 858

Going ahead to step 7:
When dividing 5077 by 858, we get 5 with a remainder of 787.
The next digit of our result is 5. 
Result so far: 11255.0
If we take 4290 away from 5077, we end up with 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

On to step 8:
If we divide 7870 by 858, we get 9 and a remainder of 148.
Record the quotient 9 as the next digit in the result. 
Result so far: 11255.9
If we subtract 7722 from 7870, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 9:
858 can be fit into 1480 1 times, resulting in a remainder of 622.
Put 1 as the next digit of the answer. 
Result so far: 11255.91
Subtracting 858 from 1480 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 10:
When dividing 6220 by 858, we get 7 with a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 11255.917
Subtract 6006 from 6220 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
If we divide 2140 by 858, we get 2 and a remainder of 424.
Record the quotient 2 as the next digit in the result. 
Result so far: 11255.9172
Subtracting 1716 from 2140 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 12:
858 can be fit into 4240 4 times, resulting in a remainder of 808.
Use 4 as the next digit of our solution. 
Result so far: 11255.91724
Deduct 3432 from 4240 and we're left with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Advancing to step 13:
If we divide 8080 by 858, we get 9 and a remainder of 358.
Use 9 as the next digit of our solution. 
Result so far: 11255.917249
Subtract 7722 from 8080 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 14:
The number 858 fits into 3580 4 times, leaving a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 11255.9172494
The remainder is 148 after subtracting 3432 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 15:
858 can be fit into 1480 1 times, resulting in a remainder of 622.
Record the quotient 1 as the next digit in the result. 
Result so far: 11255.91724941
Subtract 858 from 1480 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

In conclusion, the division gives 11255.91724941 with a balance of 6.22e-07.
