688740 ÷ 10 
The aim is to understand the frequency of 10 in 688740.

On to step 1:
When dividing 6 by 10, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 10

Advancing to step 2:
10 can be fit into 68 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 60 from 68 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 10

Step 3:
The number 10 fits into 88 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 80 from 88 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 10

Moving on to step 4:
87 divided by 10 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 688.0
If we take 80 away from 87, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 10

Step 5:
The number 10 fits into 74 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 6887.0
If we subtract 70 from 74, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 10

Let's proceed to step 6:
10 goes into 40 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 68874.0
The remainder is 0 after subtracting 40 from 40.
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:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 68874.0
Subtract 0 from 0 to get 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 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 68874.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 68874.0 with a remaining 0.0.
