We look at the division of 7420 by 10 
The aim is to understand the frequency of 10 in 7420.

Step 1:
10 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 10

On to step 2:
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: 7.0
Subtract 70 from 74 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 10

Step 3:
If we divide 42 by 10, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 40 from 42 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 10

Going ahead to step 4:
20 divided by 10 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 742.0
Subtracting 20 from 20 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 5:
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: 742.0
Deduct 0 from 0 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.

Let's proceed to step 6:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 742.0
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 742.0 with a remaining 0.0.
