We're dividing 57525363 by 857 
The aim is to understand the frequency of 857 in 57525363.

On to step 1:
When dividing 5 by 857, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 857

Advancing to step 2:
857 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 857

Let's proceed to step 3:
857 goes into 575 0 times with a remainder of 575.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 575 to get 575.
Take the next digit (2) from the dividend and append it to 575, then repeat: 5752 / 857

On to step 4:
5752 divided by 857 is 6 with a remainder of 610.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 5142 from 5752 leaves us with 610.
Grab the next digit (5) from the dividend, add it to 610, then carry on: 6105 / 857

Advancing to step 5:
6105 divided by 857 is 7 with a remainder of 106.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 5999 from 6105 leaves us with 106.
Append the next digit (3) from the dividend to 106 and continue with: 1063 / 857

Step 6:
1063 divided by 857 is 1 with a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 671.0
If we subtract 857 from 1063, we get 206.
Bring next digit (6) of the dividend behind the 206 and repeat the process: 2066 / 857

Let's proceed to step 7:
The number 857 fits into 2066 2 times, leaving a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 6712.0
If we subtract 1714 from 2066, we get 352.
Bring next digit (3) of the dividend behind the 352 and repeat the process: 3523 / 857

Going ahead to step 8:
If we divide 3523 by 857, we get 4 and a remainder of 95.
The next digit of our result is 4. 
Result so far: 67124.0
If we subtract 3428 from 3523, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 9:
If we divide 950 by 857, we get 1 and a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 67124.1
Deduct 857 from 950 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 10:
930 divided by 857 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 67124.11
Subtract 857 from 930 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

After the division, we end up with 67124.11 and a remainder of 0.073.
