We divide 67898 by 7
The aim is to understand the frequency of 7 in 67898.

Going ahead to step 1:
6 divided by 7 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 7

On to step 2:
When dividing 67 by 7, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 4 after subtracting 63 from 67.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 7

Going ahead to step 3:
7 can be fit into 48 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 96.0
If we take 42 away from 48, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 7

Going ahead to step 4:
When dividing 69 by 7, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 969.0
Subtracting 63 from 69 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

On to step 5:
7 goes into 68 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 9699.0
If we take 63 away from 68, 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.

Step 6:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 9699.7
If we subtract 49 from 50, we 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.

Advancing to step 7:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 9699.71
Subtracting 7 from 10 leaves us with 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 8:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 9699.714
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 9699.7142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 9699.71428
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.

Going ahead to step 11:
When dividing 40 by 7, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9699.714285
Subtracting 35 from 40 leaves us 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.

Step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 9699.7142857
If we subtract 49 from 50, we 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.

Step 13:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 9699.71428571
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.

The final outcome is 9699.71428571, with a leftover of 3e-09.
