We're dividing 100856 by 7 
The aim is to understand the frequency of 7 in 100856.

Advancing to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 7

Let's proceed to step 2:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 7 from 10 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

Step 3:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 28 from 30 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 7

Step 4:
7 can be fit into 28 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 28 from 28 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Going ahead to step 5:
7 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 1440.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Going ahead to step 6:
If we divide 56 by 7, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 14408.0
Deduct 56 from 56 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
7 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14408.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 7, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14408.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 14408.0 with a remainder of 0.0.
