7138570 ÷ 10 
The aim is to understand the frequency of 10 in 7138570.

Moving on to step 1:
When dividing 7 by 10, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 10

Step 2:
10 goes into 71 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 70 from 71 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 10

Step 3:
If we divide 13 by 10, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 3 after subtracting 10 from 13.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 10

On to step 4:
10 can be fit into 38 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 713.0
Deduct 30 from 38 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 10

Step 5:
10 goes into 85 8 times with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 7138.0
If we subtract 80 from 85, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 10

Going ahead to step 6:
The number 10 fits into 57 5 times, leaving a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 71385.0
If we take 50 away from 57, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 10

Let's proceed to step 7:
10 goes into 70 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 713857.0
If we subtract 70 from 70, we 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.

Going ahead to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 713857.0
If we subtract 0 from 0, we 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.

Step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 713857.0
Subtracting 0 from 0 leaves us 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 713857.0 with a remainder of 0.0.
