993437 divided by 7 
The aim is to understand the frequency of 7 in 993437.

Let's proceed to step 1:
7 goes into 9 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 7 away from 9, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Advancing to step 2:
When dividing 29 by 7, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 28 from 29 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 7

Advancing to step 3:
7 can be fit into 13 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 141.0
The remainder is 6 after subtracting 7 from 13.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 7

Let's proceed to step 4:
If we divide 64 by 7, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 1419.0
Subtracting 63 from 64 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 7

Moving on to step 5:
7 can be fit into 13 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 14191.0
Deduct 7 from 13 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 7

Advancing to step 6:
7 goes into 67 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 141919.0
Deduct 63 from 67 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.

Going ahead to step 7:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 141919.5
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 141919.57
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 9:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 141919.571
Subtract 7 from 10 to 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.

Let's proceed to step 10:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 141919.5714
Deduct 28 from 30 and we're left 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.

Moving on to step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 141919.57142
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.

Advancing to step 12:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 141919.571428
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.

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: 141919.5714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 141919.57142857
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 quotient of the division is 141919.57142857, and the remainder is 1e-09.
