We divide 5623028 by 7
The aim is to understand the frequency of 7 in 5623028.

Advancing to step 1:
The number 7 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Going ahead to step 2:
56 divided by 7 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
If we take 56 away from 56, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 7

On to step 3:
7 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 7

Let's proceed to step 4:
The number 7 fits into 23 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 803.0
If we take 21 away from 23, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Going ahead to step 5:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 8032.0
Subtract 14 from 20 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 7

Let's proceed to step 6:
62 divided by 7 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 80328.0
Subtract 56 from 62 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 7

On to step 7:
If we divide 68 by 7, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 803289.0
Subtract 63 from 68 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.

On to step 8:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 803289.7
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.

Going ahead to step 9:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 803289.71
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.

Going ahead to step 10:
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: 803289.714
Deduct 28 from 30 and we're left 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.

Advancing to step 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 803289.7142
Subtract 14 from 20 to 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.

Let's proceed to step 12:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 803289.71428
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.

On to step 13:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 803289.714285
Subtracting 35 from 40 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.

Moving on to step 14:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 803289.7142857
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.

Going ahead to step 15:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 803289.71428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 803289.71428571 and a remainder of 3e-09.
