We divide 357523 by 7
The aim is to understand the frequency of 7 in 357523.

Moving on to step 1:
The number 7 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 7

Moving on to step 2:
7 can be fit into 35 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 35 from 35 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 7

Step 3:
7 can be fit into 7 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Let's proceed to step 4:
The number 7 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 510.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 7

On to step 5:
If we divide 52 by 7, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 5107.0
The remainder is 3 after subtracting 49 from 52.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 7

Going ahead to step 6:
If we divide 33 by 7, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 51074.0
Deduct 28 from 33 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.

Going ahead to step 7:
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: 51074.7
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.

Going ahead to step 8:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 51074.71
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 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 51074.714
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.

Let's proceed to step 10:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 51074.7142
Deduct 14 from 20 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.

Let's proceed to step 11:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 51074.71428
Deduct 56 from 60 and we're left 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.

Let's proceed to step 12:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 51074.714285
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.

Let's proceed to step 13:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 51074.7142857
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 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 51074.71428571
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.

The quotient of the division is 51074.71428571, and the remainder is 3e-09.
