We're dividing 705270 by 7 
The aim is to understand the frequency of 7 in 705270.

Step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 7 from 7.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 7

Going ahead to step 2:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 7

On to step 3:
If we divide 5 by 7, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 7

Step 4:
7 can be fit into 52 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 1007.0
Subtract 49 from 52 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 7

On to step 5:
7 goes into 37 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 10075.0
The remainder is 2 after subtracting 35 from 37.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 7

Going ahead to step 6:
If we divide 20 by 7, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 100752.0
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 7 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 100752.8
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 100752.85
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 100752.857
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 100752.8571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 100752.85714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 100752.857142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 100752.8571428
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 100752.85714285
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 100752.85714285 with a remainder of 5e-09.
