17556944 ÷ 858 
The aim is to understand the frequency of 858 in 17556944.

Moving on to step 1:
858 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 858

Let's proceed to step 2:
858 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 858

Going ahead to step 3:
175 divided by 858 is 0 with a remainder of 175.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 175 and we're left with 175.
Take the next digit (5) from the dividend and append it to 175, then repeat: 1755 / 858

Step 4:
858 goes into 1755 2 times with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1716 from 1755, we get 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 858

On to step 5:
When dividing 396 by 858, we get 0 with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 396 leaves us with 396.
Grab the next digit (9) from the dividend, add it to 396, then carry on: 3969 / 858

Advancing to step 6:
The number 858 fits into 3969 4 times, leaving a remainder of 537.
The next digit of our result is 4. 
Result so far: 204.0
Subtracting 3432 from 3969 leaves us with 537.
Append the next digit (4) from the dividend to 537 and continue with: 5374 / 858

Step 7:
If we divide 5374 by 858, we get 6 and a remainder of 226.
Write down 6 as next digit of the result. 
Result so far: 2046.0
Subtracting 5148 from 5374 leaves us with 226.
Append the next digit (4) from the dividend to 226 and continue with: 2264 / 858

On to step 8:
858 can be fit into 2264 2 times, resulting in a remainder of 548.
Use 2 as the next digit of our solution. 
Result so far: 20462.0
Subtracting 1716 from 2264 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 9:
5480 divided by 858 is 6 with a remainder of 332.
Record the quotient 6 as the next digit in the result. 
Result so far: 20462.6
If we subtract 5148 from 5480, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 10:
858 goes into 3320 3 times with a remainder of 746.
Write down 3 as next digit of the result. 
Result so far: 20462.63
Subtract 2574 from 3320 to get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Advancing to step 11:
If we divide 7460 by 858, we get 8 and a remainder of 596.
The number 8 becomes the next digit in our result. 
Result so far: 20462.638
If we subtract 6864 from 7460, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 12:
If we divide 5960 by 858, we get 6 and a remainder of 812.
Put 6 as the next digit of the answer. 
Result so far: 20462.6386
The remainder is 812 after subtracting 5148 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Going ahead to step 13:
The number 858 fits into 8120 9 times, leaving a remainder of 398.
The next digit of our result is 9. 
Result so far: 20462.63869
Deduct 7722 from 8120 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 14:
858 can be fit into 3980 4 times, resulting in a remainder of 548.
The next digit of our result is 4. 
Result so far: 20462.638694
If we subtract 3432 from 3980, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 15:
5480 divided by 858 is 6 with a remainder of 332.
The number 6 becomes the next digit in our result. 
Result so far: 20462.6386946
Subtracting 5148 from 5480 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 16:
When dividing 3320 by 858, we get 3 with a remainder of 746.
The next digit of our result is 3. 
Result so far: 20462.63869463
Deduct 2574 from 3320 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

The final outcome is 20462.63869463, with a leftover of 7.46e-07.
