980437 divided by 7 
The aim is to understand the frequency of 7 in 980437.

Let's proceed to step 1:
7 can be fit into 9 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 7 from 9, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 7

Moving on to step 2:
The number 7 fits into 28 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 0 after subtracting 28 from 28.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 7

On to step 3:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 7

Let's proceed to step 4:
4 divided by 7 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 1400.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Step 5:
7 goes into 43 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 14006.0
The remainder is 1 after subtracting 42 from 43.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

Step 6:
7 goes into 17 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 140062.0
If we subtract 14 from 17, 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.

On to step 7:
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: 140062.4
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.

Let's proceed to step 8:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 140062.42
Subtract 14 from 20 to 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.

Let's proceed to step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 140062.428
The remainder is 4 after subtracting 56 from 60.
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 10:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 140062.4285
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.

Advancing to step 11:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 140062.42857
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 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 140062.428571
The remainder is 3 after subtracting 7 from 10.
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 13:
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: 140062.4285714
The remainder is 2 after subtracting 28 from 30.
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 14:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 140062.42857142
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.

Our division results in 140062.42857142 with a remaining 6e-09.
