101391 ÷ 10 
The aim is to understand the frequency of 10 in 101391.

On to step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 10

Moving on to step 2:
When dividing 10 by 10, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 10 from 10 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 10

Advancing to step 3:
When dividing 1 by 10, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 10

Going ahead to step 4:
The number 10 fits into 13 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 10 from 13 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 10

Step 5:
If we divide 39 by 10, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
If we take 30 away from 39, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 10

On to step 6:
The number 10 fits into 91 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 10139.0
Subtracting 90 from 91 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 can be fit into 10 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 10139.1
Subtracting 10 from 10 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.

On to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10139.1
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.

Going ahead to step 9:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10139.1
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.

The final result is 10139.1 with a remainder of 0.0.
