900908 ÷ 7 
We want to figure out the number of times 900908 can be divided by 7.

On 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
Subtract 7 from 9 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Step 2:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 14 from 20 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 7

On to step 3:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 128.0
If we subtract 56 from 60, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 7

On to step 4:
When dividing 49 by 7, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1287.0
Subtract 49 from 49 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 7

Going ahead to step 5:
If we divide 0 by 7, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12870.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 7

On to step 6:
If we divide 8 by 7, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 128701.0
If we subtract 7 from 8, we 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.

Let's proceed to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 128701.1
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.

On to step 8:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 128701.14
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 9:
20 divided by 7 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 128701.142
Subtracting 14 from 20 leaves us 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.

On to step 10:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 128701.1428
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.

Let's proceed to step 11:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 128701.14285
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.

Moving on to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 128701.142857
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.

Moving on to step 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 128701.1428571
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.

Moving on to step 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 128701.14285714
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.

The final result is 128701.14285714 with a remainder of 2e-09.
