We divide 485651 by 7
The aim is to understand the frequency of 7 in 485651.

On to step 1:
When dividing 4 by 7, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 7

Step 2:
If we divide 48 by 7, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 42 from 48 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 7

Moving on to step 3:
The number 7 fits into 65 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 63 from 65 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 7

Going ahead to step 4:
The number 7 fits into 26 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 693.0
Subtracting 21 from 26 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 7

Advancing to step 5:
If we divide 55 by 7, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 6937.0
Deduct 49 from 55 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 7

Going ahead to step 6:
7 goes into 61 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 69378.0
Subtracting 56 from 61 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.

Advancing to step 7:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 69378.7
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.

Going ahead to step 8:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 69378.71
If we take 7 away from 10, we end up 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 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 69378.714
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.

Advancing to step 10:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 69378.7142
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.

Advancing to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 69378.71428
If we take 56 away from 60, we end up 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.

Step 12:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 69378.714285
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.

Step 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 69378.7142857
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 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 69378.71428571
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.

Our division results in 69378.71428571 with a remaining 3e-09.
