We're dividing 617691 by 7 
The aim is to understand the frequency of 7 in 617691.

Going ahead to step 1:
7 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 7

Step 2:
61 divided by 7 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 56 from 61 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 7

Step 3:
7 can be fit into 57 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtracting 56 from 57 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 7

Step 4:
If we divide 16 by 7, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 882.0
Deduct 14 from 16 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Step 5:
The number 7 fits into 29 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 8824.0
The remainder is 1 after subtracting 28 from 29.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 7

Going ahead to step 6:
The number 7 fits into 11 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 88241.0
The remainder is 4 after subtracting 7 from 11.
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 7:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 88241.5
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.

Step 8:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 88241.57
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 88241.571
Deduct 7 from 10 and we're left 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.

Advancing to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 88241.5714
Subtracting 28 from 30 leaves us 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.

Step 11:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 88241.57142
If we take 14 away from 20, we end up 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.

Going ahead to step 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 88241.571428
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.

Advancing to step 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 88241.5714285
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 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 88241.57142857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 88241.57142857 with a remaining 1e-09.
