736800 ÷ 7 
The aim is to understand the frequency of 7 in 736800.

Step 1:
7 goes into 7 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 7 away from 7, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 7

Moving on to step 2:
7 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 7

Let's proceed to step 3:
7 can be fit into 36 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 35 away from 36, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 7

Let's proceed to step 4:
7 can be fit into 18 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1052.0
If we subtract 14 from 18, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 7

On to step 5:
7 goes into 40 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 10525.0
Subtracting 35 from 40 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 7

Going ahead to step 6:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 105257.0
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 7:
When dividing 10 by 7, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 105257.1
Subtracting 7 from 10 leaves us 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:
When dividing 30 by 7, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 105257.14
If we subtract 28 from 30, we 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.

Step 9:
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: 105257.142
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.

On to step 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 105257.1428
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 11:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 105257.14285
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.

Let's proceed 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: 105257.142857
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.

Step 13:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 105257.1428571
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 14:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 105257.14285714
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.

In conclusion, the division gives 105257.14285714 with a balance of 2e-09.
