We're dividing 737489 by 7 
The aim is to understand the frequency of 7 in 737489.

Moving on to step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 7 away from 7, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 7

On to step 2:
If we divide 3 by 7, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 7

Moving on to step 3:
37 divided by 7 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 35 from 37 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 7

On to step 4:
The number 7 fits into 24 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1053.0
If we take 21 away from 24, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 7

Going ahead to step 5:
7 goes into 38 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 10535.0
If we subtract 35 from 38, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 7

Let's proceed to step 6:
39 divided by 7 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 105355.0
The remainder is 4 after subtracting 35 from 39.
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 7:
If we divide 40 by 7, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 105355.5
Deduct 35 from 40 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.

Moving on to step 8:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 105355.57
Subtract 49 from 50 to 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.

Let's proceed to step 9:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 105355.571
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.

Advancing to step 10:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 105355.5714
Subtract 28 from 30 to 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.

Going ahead to step 11:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 105355.57142
If we take 14 away from 20, we end up 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.

Moving on 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: 105355.571428
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.

Advancing to step 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 105355.5714285
Deduct 35 from 40 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.

Step 14:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 105355.57142857
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.

The final result is 105355.57142857 with a remainder of 1e-09.
