400268 ÷ 7 
We want to figure out the number of times 400268 can be divided by 7.

Advancing to step 1:
7 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 7

Let's proceed to step 2:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 35 from 40 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 7

Moving on to step 3:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 49 from 50 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 7

On to step 4:
The number 7 fits into 12 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 571.0
The remainder is 5 after subtracting 7 from 12.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 7

Going ahead to step 5:
When dividing 56 by 7, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 5718.0
The remainder is 0 after subtracting 56 from 56.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 7

Advancing to step 6:
If we divide 8 by 7, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 57181.0
The remainder is 1 after subtracting 7 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 57181.1
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.

On to step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 57181.14
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.

Advancing to step 9:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 57181.142
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.

Going ahead to step 10:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 57181.1428
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.

Step 11:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 57181.14285
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.

Advancing to step 12:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 57181.142857
Subtracting 49 from 50 leaves us 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.

Going ahead to step 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 57181.1428571
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.

On to step 14:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 57181.14285714
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.

The quotient of the division is 57181.14285714, and the remainder is 2e-09.
