Let's divide 39243707 by 857
The aim is to understand the frequency of 857 in 39243707.

On to step 1:
857 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
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 857

On to step 2:
857 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 857

Advancing to step 3:
When dividing 392 by 857, we get 0 with a remainder of 392.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 392 leaves us with 392.
Include the next digit (4) from the dividend after 392, then repeat: 3924 / 857

Let's proceed to step 4:
857 can be fit into 3924 4 times, resulting in a remainder of 496.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3428 from 3924 to get 496.
Append the next digit (3) from the dividend to 496 and continue with: 4963 / 857

Step 5:
857 goes into 4963 5 times with a remainder of 678.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 4285 from 4963 to get 678.
Grab the next digit (7) from the dividend, add it to 678, then carry on: 6787 / 857

On to step 6:
857 goes into 6787 7 times with a remainder of 788.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
Subtracting 5999 from 6787 leaves us with 788.
Fetch the next digit (0) from the dividend, attach it to 788 and continue: 7880 / 857

Moving on to step 7:
7880 divided by 857 is 9 with a remainder of 167.
The next digit of our result is 9. 
Result so far: 4579.0
Subtract 7713 from 7880 to get 167.
Include the next digit (7) from the dividend after 167, then repeat: 1677 / 857

Step 8:
857 can be fit into 1677 1 times, resulting in a remainder of 820.
Record the quotient 1 as the next digit in the result. 
Result so far: 45791.0
If we subtract 857 from 1677, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

On to step 9:
8200 divided by 857 is 9 with a remainder of 487.
Record the quotient 9 as the next digit in the result. 
Result so far: 45791.9
Deduct 7713 from 8200 and we're left with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 10:
When dividing 4870 by 857, we get 5 with a remainder of 585.
Record the quotient 5 as the next digit in the result. 
Result so far: 45791.95
Subtracting 4285 from 4870 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 11:
If we divide 5850 by 857, we get 6 and a remainder of 708.
Record the quotient 6 as the next digit in the result. 
Result so far: 45791.956
Deduct 5142 from 5850 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

On to step 12:
When dividing 7080 by 857, we get 8 with a remainder of 224.
Write down 8 as next digit of the result. 
Result so far: 45791.9568
If we take 6856 away from 7080, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 13:
When dividing 2240 by 857, we get 2 with a remainder of 526.
Put 2 as the next digit of the answer. 
Result so far: 45791.95682
If we subtract 1714 from 2240, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

On to step 14:
The number 857 fits into 5260 6 times, leaving a remainder of 118.
Use 6 as the next digit of our solution. 
Result so far: 45791.956826
If we take 5142 away from 5260, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 15:
857 can be fit into 1180 1 times, resulting in a remainder of 323.
Write down 1 as next digit of the result. 
Result so far: 45791.9568261
If we take 857 away from 1180, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 16:
When dividing 3230 by 857, we get 3 with a remainder of 659.
The number 3 becomes the next digit in our result. 
Result so far: 45791.95682613
Subtract 2571 from 3230 to get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

In conclusion, the division gives 45791.95682613 with a balance of 6.59e-07.
