Let's divide 82458923 by 7
We want to figure out the number of times 82458923 can be divided by 7.

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.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 7

Let's proceed to step 2:
The number 7 fits into 12 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 7 from 12 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 7

Step 3:
7 can be fit into 54 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 49 from 54 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 7

Advancing to step 4:
If we divide 55 by 7, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1177.0
Deduct 49 from 55 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

Let's proceed to step 5:
7 goes into 68 9 times with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 11779.0
If we subtract 63 from 68, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 7

Let's proceed to step 6:
The number 7 fits into 59 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 117798.0
If we take 56 away from 59, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 7

Moving on to step 7:
The number 7 fits into 32 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1177984.0
If we subtract 28 from 32, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 7

Moving on to step 8:
If we divide 43 by 7, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 11779846.0
Subtract 42 from 43 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.

Advancing to step 9:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 11779846.1
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.

Let's proceed to step 10:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 11779846.14
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.

Let's proceed to step 11:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 11779846.142
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.

Advancing to step 12:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11779846.1428
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:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 11779846.14285
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.

Step 14:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 11779846.142857
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.

Let's proceed to step 15:
When dividing 10 by 7, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11779846.1428571
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.

Advancing to step 16:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 11779846.14285714
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.

After the division, we end up with 11779846.14285714 and a remainder of 2e-09.
