400489 ÷ 7 
We want to divide 400489 by 7.

Step 1:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 7

Moving on to step 2:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 5 after subtracting 35 from 40.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 7

Moving on to step 3:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 49 from 50 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 7

Moving on to step 4:
7 goes into 14 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 572.0
Subtracting 14 from 14 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 7

Advancing to step 5:
When dividing 8 by 7, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 5721.0
Deduct 7 from 8 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 7

Let's proceed to step 6:
7 can be fit into 19 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 57212.0
Subtract 14 from 19 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.

Going ahead to step 7:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 57212.7
Subtract 49 from 50 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.

Let's proceed to step 8:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 57212.71
Subtracting 7 from 10 leaves us 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.

Step 9:
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: 57212.714
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 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 57212.7142
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.

Moving on to step 11:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 57212.71428
If we subtract 56 from 60, we 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 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 57212.714285
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.

On to step 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 57212.7142857
Subtract 49 from 50 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.

On to step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 57212.71428571
Subtracting 7 from 10 leaves us 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.

The quotient of the division is 57212.71428571, and the remainder is 3e-09.
