538790 divided by 7 
The aim is to understand the frequency of 7 in 538790.

Moving on to step 1:
The number 7 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 7

Let's proceed to step 2:
The number 7 fits into 53 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 49 from 53 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 7

Moving on to step 3:
48 divided by 7 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 42 from 48 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 7

Going ahead to step 4:
7 goes into 67 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 769.0
If we subtract 63 from 67, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 7

Moving on to step 5:
When dividing 49 by 7, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7697.0
Subtracting 49 from 49 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 7

Step 6:
When dividing 0 by 7, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 76970.0
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.

Let's proceed to step 7:
When dividing 0 by 7, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 76970.0
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 8:
7 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 76970.0
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 quotient of the division is 76970.0, and the remainder is 0.0.
