We're dividing 747685 by 7 
The aim is to understand the frequency of 7 in 747685.

Going ahead to step 1:
7 can be fit into 7 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 7

Moving on to step 2:
7 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 7

Let's proceed to step 3:
The number 7 fits into 47 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 106.0
The remainder is 5 after subtracting 42 from 47.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 7

Let's proceed to step 4:
If we divide 56 by 7, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1068.0
If we subtract 56 from 56, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 7

Going ahead to step 5:
If we divide 8 by 7, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 10681.0
Deduct 7 from 8 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 7

Let's proceed to step 6:
When dividing 15 by 7, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 106812.0
The remainder is 1 after subtracting 14 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 106812.1
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:
If we divide 30 by 7, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 106812.14
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.

Going ahead to step 9:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 106812.142
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.

Step 10:
7 goes into 60 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 106812.1428
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.

Going ahead to step 11:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 106812.14285
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.

Moving on to step 12:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 106812.142857
Deduct 49 from 50 and we're left 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.

Let's proceed to step 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 106812.1428571
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.

Moving on to step 14:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 106812.14285714
If we take 28 away from 30, we end up 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.

The final outcome is 106812.14285714, with a leftover of 2e-09.
