603483 ÷ 7 
The aim is to understand the frequency of 7 in 603483.

Going ahead to step 1:
The number 7 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 7

Step 2:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 56 from 60 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Step 3:
43 divided by 7 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 86.0
The remainder is 1 after subtracting 42 from 43.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 7

Step 4:
The number 7 fits into 14 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 862.0
If we subtract 14 from 14, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

Let's proceed to step 5:
When dividing 8 by 7, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 8621.0
Deduct 7 from 8 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 7

Let's proceed to step 6:
If we divide 13 by 7, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 86211.0
Deduct 7 from 13 and we're left 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.

Advancing to step 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 86211.8
If we subtract 56 from 60, we 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 8:
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: 86211.85
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.

Step 9:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 86211.857
If we take 49 away from 50, we end up 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 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 86211.8571
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.

Going ahead to step 11:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 86211.85714
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.

Moving on to step 12:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 86211.857142
If we subtract 14 from 20, 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.

Step 13:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 86211.8571428
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.

Moving on to step 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 86211.85714285
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.

Our division results in 86211.85714285 with a remaining 5e-09.
