We're dividing 35929 by 7 
The aim is to understand the frequency of 7 in 35929.

On to step 1:
When dividing 3 by 7, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 7

On to step 2:
7 can be fit into 35 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 35 from 35 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Advancing to step 3:
The number 7 fits into 9 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 7 from 9, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 7

Going ahead to step 4:
22 divided by 7 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
Deduct 21 from 22 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 7

Step 5:
If we divide 19 by 7, we get 2 and a remainder of 5.
The next digit of our result is 2. 
Result so far: 5132.0
Subtract 14 from 19 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.

Advancing to step 6:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 5132.7
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 7:
7 goes into 10 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 5132.71
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.

Let's proceed to step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 5132.714
The remainder is 2 after subtracting 28 from 30.
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:
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: 5132.7142
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.

Going ahead to step 10:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 5132.71428
Subtracting 56 from 60 leaves us 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.

Going ahead to step 11:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5132.714285
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.

Going ahead to step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 5132.7142857
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.

Moving on to step 13:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 5132.71428571
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 5132.71428571 with a remaining 3e-09.
