We're dividing 898813 by 7 
The aim is to understand the frequency of 7 in 898813.

On to step 1:
7 goes into 8 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Step 2:
19 divided by 7 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 14 from 19 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 7

Step 3:
When dividing 58 by 7, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we take 56 away from 58, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 7

Step 4:
7 goes into 28 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 1284.0
Subtracting 28 from 28 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 7

Step 5:
The number 7 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 12840.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 7

Step 6:
7 goes into 13 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 128401.0
If we subtract 7 from 13, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 128401.8
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.

Going ahead to step 8:
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: 128401.85
Subtract 35 from 40 to 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.

Moving on to step 9:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 128401.857
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:
When dividing 10 by 7, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 128401.8571
If we subtract 7 from 10, we 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:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 128401.85714
Subtract 28 from 30 to 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.

Going ahead to step 12:
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: 128401.857142
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 13:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 128401.8571428
The remainder is 4 after subtracting 56 from 60.
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 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 128401.85714285
Deduct 35 from 40 and we're left 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.

In conclusion, the division gives 128401.85714285 with a balance of 5e-09.
