Let's divide 37647323 by 7
The aim is to understand the frequency of 7 in 37647323.

Step 1:
3 divided by 7 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 7

Let's proceed to step 2:
7 can be fit into 37 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 35 from 37 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 7

Advancing to step 3:
7 goes into 26 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 21 from 26 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 7

Let's proceed to step 4:
If we divide 54 by 7, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 537.0
Subtracting 49 from 54 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 7

Let's proceed to step 5:
When dividing 57 by 7, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 5378.0
If we subtract 56 from 57, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 7

Moving on to step 6:
7 can be fit into 13 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 53781.0
The remainder is 6 after subtracting 7 from 13.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 7

On to step 7:
7 can be fit into 62 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 537818.0
Deduct 56 from 62 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 7

Step 8:
7 can be fit into 63 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 5378189.0
Deduct 63 from 63 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 7, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5378189.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
7 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5378189.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5378189.0 and a remainder of 0.0.
