We look at the division of 91681716 by 856 
The aim is to understand the frequency of 856 in 91681716.

Let's proceed to step 1:
856 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 856

Step 2:
856 goes into 91 0 times with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 856

Moving on to step 3:
916 divided by 856 is 1 with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 856 away from 916, we end up with 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 856

Moving on to step 4:
If we divide 608 by 856, we get 0 and a remainder of 608.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 608 and we're left with 608.
Include the next digit (1) from the dividend after 608, then repeat: 6081 / 856

Moving on to step 5:
856 goes into 6081 7 times with a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 89 after subtracting 5992 from 6081.
Bring next digit (7) of the dividend behind the 89 and repeat the process: 897 / 856

Step 6:
When dividing 897 by 856, we get 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1071.0
The remainder is 41 after subtracting 856 from 897.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 856

Going ahead to step 7:
856 can be fit into 411 0 times, resulting in a remainder of 411.
The next digit of our result is 0. 
Result so far: 10710.0
Subtract 0 from 411 to get 411.
Include the next digit (6) from the dividend after 411, then repeat: 4116 / 856

Let's proceed to step 8:
4116 divided by 856 is 4 with a remainder of 692.
The number 4 becomes the next digit in our result. 
Result so far: 107104.0
Subtracting 3424 from 4116 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

On to step 9:
The number 856 fits into 6920 8 times, leaving a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 107104.8
Deduct 6848 from 6920 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
When dividing 720 by 856, we get 0 with a remainder of 720.
The next digit of our result is 0. 
Result so far: 107104.8
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 11:
If we divide 7200 by 856, we get 8 and a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 107104.808
Subtracting 6848 from 7200 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 12:
If we divide 3520 by 856, we get 4 and a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 107104.8084
Subtract 3424 from 3520 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 13:
The number 856 fits into 960 1 times, leaving a remainder of 104.
Use 1 as the next digit of our solution. 
Result so far: 107104.80841
Subtract 856 from 960 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 14:
When dividing 1040 by 856, we get 1 with a remainder of 184.
The next digit of our result is 1. 
Result so far: 107104.808411
If we take 856 away from 1040, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The quotient of the division is 107104.808411, and the remainder is 1.84e-05.
