We divide 987293 by 7
The aim is to understand the frequency of 7 in 987293.

Moving on to step 1:
If we divide 9 by 7, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 7 from 9, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 7

On to step 2:
When dividing 28 by 7, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 28 from 28 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 7

Moving on to step 3:
7 can be fit into 7 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtract 7 from 7 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 7

Going ahead to step 4:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1410.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 7

Step 5:
If we divide 29 by 7, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 14104.0
If we take 28 away from 29, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 7

Let's proceed to step 6:
If we divide 13 by 7, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 141041.0
If we take 7 away from 13, 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.

Step 7:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 141041.8
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.

Moving on to step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 141041.85
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 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 141041.857
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.

On to step 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 141041.8571
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.

Moving on to step 11:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 141041.85714
If we take 28 away from 30, we end up 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.

Step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 141041.857142
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.

Moving on to step 13:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 141041.8571428
Deduct 56 from 60 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.

On to step 14:
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: 141041.85714285
Subtract 35 from 40 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.

The quotient of the division is 141041.85714285, and the remainder is 5e-09.
