We look at the division of 64333670 by 857 
The aim is to understand the frequency of 857 in 64333670.

Step 1:
857 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 857

Step 2:
857 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 857

Step 3:
643 divided by 857 is 0 with a remainder of 643.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 643 and we're left with 643.
Take the next digit (3) from the dividend and append it to 643, then repeat: 6433 / 857

Moving on to step 4:
857 goes into 6433 7 times with a remainder of 434.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5999 away from 6433, we end up with 434.
Include the next digit (3) from the dividend after 434, then repeat: 4343 / 857

Moving on to step 5:
The number 857 fits into 4343 5 times, leaving a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Deduct 4285 from 4343 and we're left with 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 857

Moving on to step 6:
If we divide 586 by 857, we get 0 and a remainder of 586.
Put 0 as the next digit of the answer. 
Result so far: 750.0
Deduct 0 from 586 and we're left with 586.
Take the next digit (7) from the dividend and append it to 586, then repeat: 5867 / 857

Step 7:
The number 857 fits into 5867 6 times, leaving a remainder of 725.
Put 6 as the next digit of the answer. 
Result so far: 7506.0
Subtracting 5142 from 5867 leaves us with 725.
Append the next digit (0) from the dividend to 725 and continue with: 7250 / 857

Let's proceed to step 8:
857 goes into 7250 8 times with a remainder of 394.
Record the quotient 8 as the next digit in the result. 
Result so far: 75068.0
Deduct 6856 from 7250 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 9:
The number 857 fits into 3940 4 times, leaving a remainder of 512.
Record the quotient 4 as the next digit in the result. 
Result so far: 75068.4
Subtracting 3428 from 3940 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 10:
5120 divided by 857 is 5 with a remainder of 835.
Record the quotient 5 as the next digit in the result. 
Result so far: 75068.45
Deduct 4285 from 5120 and we're left with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

On to step 11:
If we divide 8350 by 857, we get 9 and a remainder of 637.
Record the quotient 9 as the next digit in the result. 
Result so far: 75068.459
Subtract 7713 from 8350 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

On to step 12:
The number 857 fits into 6370 7 times, leaving a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 75068.4597
Subtracting 5999 from 6370 leaves us with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Advancing to step 13:
If we divide 3710 by 857, we get 4 and a remainder of 282.
The next digit of our result is 4. 
Result so far: 75068.45974
If we take 3428 away from 3710, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 14:
The number 857 fits into 2820 3 times, leaving a remainder of 249.
Record the quotient 3 as the next digit in the result. 
Result so far: 75068.459743
Deduct 2571 from 2820 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 15:
857 can be fit into 2490 2 times, resulting in a remainder of 776.
The next digit of our result is 2. 
Result so far: 75068.4597432
If we subtract 1714 from 2490, we get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Let's proceed to step 16:
857 goes into 7760 9 times with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 75068.45974329
Subtracting 7713 from 7760 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 75068.45974329 with a remainder of 4.7e-08.
