We look at the division of 75053708 by 857 
The aim is to understand the frequency of 857 in 75053708.

Moving on to step 1:
7 divided by 857 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 857

Moving on to step 2:
75 divided by 857 is 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 857

Advancing to step 3:
The number 857 fits into 750 0 times, leaving a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 750 after subtracting 0 from 750.
Fetch the next digit (5) from the dividend, attach it to 750 and continue: 7505 / 857

Let's proceed to step 4:
When dividing 7505 by 857, we get 8 with a remainder of 649.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 6856 from 7505 and we're left with 649.
Fetch the next digit (3) from the dividend, attach it to 649 and continue: 6493 / 857

Step 5:
857 can be fit into 6493 7 times, resulting in a remainder of 494.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 5999 from 6493, we get 494.
Append the next digit (7) from the dividend to 494 and continue with: 4947 / 857

Advancing to step 6:
If we divide 4947 by 857, we get 5 and a remainder of 662.
Write down 5 as next digit of the result. 
Result so far: 875.0
Subtract 4285 from 4947 to get 662.
Include the next digit (0) from the dividend after 662, then repeat: 6620 / 857

Step 7:
857 goes into 6620 7 times with a remainder of 621.
Put 7 as the next digit of the answer. 
Result so far: 8757.0
If we take 5999 away from 6620, we end up with 621.
Take the next digit (8) from the dividend and append it to 621, then repeat: 6218 / 857

On to step 8:
If we divide 6218 by 857, we get 7 and a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 87577.0
Subtracting 5999 from 6218 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 9:
If we divide 2190 by 857, we get 2 and a remainder of 476.
Record the quotient 2 as the next digit in the result. 
Result so far: 87577.2
Subtract 1714 from 2190 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 10:
857 goes into 4760 5 times with a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 87577.25
If we subtract 4285 from 4760, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 11:
If we divide 4750 by 857, we get 5 and a remainder of 465.
Write down 5 as next digit of the result. 
Result so far: 87577.255
Subtract 4285 from 4750 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

After the division, we end up with 87577.255 and a remainder of 0.0465.
