We're dividing 39932679 by 858 
The aim is to understand the frequency of 858 in 39932679.

Moving on to step 1:
858 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 858

Going ahead to step 2:
39 divided by 858 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 858

Moving on to step 3:
858 goes into 399 0 times with a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 399 leaves us with 399.
Take the next digit (3) from the dividend and append it to 399, then repeat: 3993 / 858

Let's proceed to step 4:
When dividing 3993 by 858, we get 4 with a remainder of 561.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3432 from 3993, we get 561.
Include the next digit (2) from the dividend after 561, then repeat: 5612 / 858

Going ahead to step 5:
858 goes into 5612 6 times with a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 5148 from 5612 leaves us with 464.
Grab the next digit (6) from the dividend, add it to 464, then carry on: 4646 / 858

On to step 6:
4646 divided by 858 is 5 with a remainder of 356.
Use 5 as the next digit of our solution. 
Result so far: 465.0
Subtracting 4290 from 4646 leaves us with 356.
Take the next digit (7) from the dividend and append it to 356, then repeat: 3567 / 858

Advancing to step 7:
3567 divided by 858 is 4 with a remainder of 135.
Use 4 as the next digit of our solution. 
Result so far: 4654.0
The remainder is 135 after subtracting 3432 from 3567.
Fetch the next digit (9) from the dividend, attach it to 135 and continue: 1359 / 858

Going ahead to step 8:
1359 divided by 858 is 1 with a remainder of 501.
The number 1 becomes the next digit in our result. 
Result so far: 46541.0
If we take 858 away from 1359, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Step 9:
5010 divided by 858 is 5 with a remainder of 720.
The next digit of our result is 5. 
Result so far: 46541.5
Subtract 4290 from 5010 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 10:
858 can be fit into 7200 8 times, resulting in a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 46541.58
If we subtract 6864 from 7200, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 11:
If we divide 3360 by 858, we get 3 and a remainder of 786.
Write down 3 as next digit of the result. 
Result so far: 46541.583
If we take 2574 away from 3360, we end up with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

On to step 12:
858 can be fit into 7860 9 times, resulting in a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 46541.5839
Subtract 7722 from 7860 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 13:
1380 divided by 858 is 1 with a remainder of 522.
Put 1 as the next digit of the answer. 
Result so far: 46541.58391
Subtracting 858 from 1380 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Let's proceed to step 14:
The number 858 fits into 5220 6 times, leaving a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 46541.583916
The remainder is 72 after subtracting 5148 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 15:
The number 858 fits into 720 0 times, leaving a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 46541.583916
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 16:
If we divide 7200 by 858, we get 8 and a remainder of 336.
The next digit of our result is 8. 
Result so far: 46541.58391608
If we take 6864 away from 7200, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The quotient of the division is 46541.58391608, and the remainder is 3.36e-07.
