We're dividing 67006906 by 857 
The aim is to understand the frequency of 857 in 67006906.

Step 1:
When dividing 6 by 857, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 857

On to step 2:
857 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 857

Advancing to step 3:
857 can be fit into 670 0 times, resulting in a remainder of 670.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 670 leaves us with 670.
Fetch the next digit (0) from the dividend, attach it to 670 and continue: 6700 / 857

Step 4:
857 goes into 6700 7 times with a remainder of 701.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 5999 away from 6700, we end up with 701.
Append the next digit (6) from the dividend to 701 and continue with: 7016 / 857

Going ahead to step 5:
7016 divided by 857 is 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 6856 from 7016 and we're left with 160.
Grab the next digit (9) from the dividend, add it to 160, then carry on: 1609 / 857

Moving on to step 6:
857 goes into 1609 1 times with a remainder of 752.
Record the quotient 1 as the next digit in the result. 
Result so far: 781.0
Subtracting 857 from 1609 leaves us with 752.
Append the next digit (0) from the dividend to 752 and continue with: 7520 / 857

On to step 7:
857 can be fit into 7520 8 times, resulting in a remainder of 664.
The next digit of our result is 8. 
Result so far: 7818.0
Deduct 6856 from 7520 and we're left with 664.
Grab the next digit (6) from the dividend, add it to 664, then carry on: 6646 / 857

Going ahead to step 8:
When dividing 6646 by 857, we get 7 with a remainder of 647.
Use 7 as the next digit of our solution. 
Result so far: 78187.0
Subtract 5999 from 6646 to get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Let's proceed to step 9:
The number 857 fits into 6470 7 times, leaving a remainder of 471.
Put 7 as the next digit of the answer. 
Result so far: 78187.7
Subtracting 5999 from 6470 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 10:
857 goes into 4710 5 times with a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 78187.75
If we take 4285 away from 4710, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 11:
857 can be fit into 4250 4 times, resulting in a remainder of 822.
Use 4 as the next digit of our solution. 
Result so far: 78187.754
Subtracting 3428 from 4250 leaves us with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

On to step 12:
8220 divided by 857 is 9 with a remainder of 507.
Record the quotient 9 as the next digit in the result. 
Result so far: 78187.7549
The remainder is 507 after subtracting 7713 from 8220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Advancing to step 13:
The number 857 fits into 5070 5 times, leaving a remainder of 785.
Use 5 as the next digit of our solution. 
Result so far: 78187.75495
Subtract 4285 from 5070 to get 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Advancing to step 14:
If we divide 7850 by 857, we get 9 and a remainder of 137.
Write down 9 as next digit of the result. 
Result so far: 78187.754959
If we subtract 7713 from 7850, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 15:
857 can be fit into 1370 1 times, resulting in a remainder of 513.
The next digit of our result is 1. 
Result so far: 78187.7549591
Subtracting 857 from 1370 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 16:
If we divide 5130 by 857, we get 5 and a remainder of 845.
The next digit of our result is 5. 
Result so far: 78187.75495915
If we take 4285 away from 5130, we end up with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Our division results in 78187.75495915 with a remaining 8.45e-07.
