Let's divide 888931 by 7
The aim is to understand the frequency of 7 in 888931.

On to step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Going ahead to step 2:
The number 7 fits into 18 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 14 from 18, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 7

Moving on to step 3:
7 goes into 48 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtracting 42 from 48 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 7

Moving on to step 4:
If we divide 69 by 7, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 1269.0
Subtract 63 from 69 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 7

On to step 5:
If we divide 63 by 7, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 12699.0
Subtract 63 from 63 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 7

Going ahead to step 6:
When dividing 1 by 7, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 126990.0
Deduct 0 from 1 and we're left 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.

Advancing to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 126990.1
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.

Advancing to step 8:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 126990.14
Subtracting 28 from 30 leaves us 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.

Let's proceed to step 9:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 126990.142
If we subtract 14 from 20, we 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.

Advancing to step 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 126990.1428
Subtract 56 from 60 to get 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 11:
If we divide 40 by 7, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 126990.14285
If we take 35 away from 40, we end up 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.

Let's proceed to step 12:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 126990.142857
If we take 49 away from 50, we end up 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.

On to step 13:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 126990.1428571
If we take 7 away from 10, we end up 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.

Advancing to step 14:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 126990.14285714
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.

Our division results in 126990.14285714 with a remaining 2e-09.
