Let's divide 449958 by 7
We're looking to find how many times 7 goes into 449958.

Step 1:
When dividing 4 by 7, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 7

Going ahead to step 2:
If we divide 44 by 7, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 42 away from 44, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Step 3:
29 divided by 7 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 28 away from 29, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 7

Moving on to step 4:
7 can be fit into 19 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 642.0
Subtracting 14 from 19 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 7

On to step 5:
The number 7 fits into 55 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 6427.0
If we take 49 away from 55, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 7

Let's proceed to step 6:
7 can be fit into 68 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 64279.0
If we subtract 63 from 68, we 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 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 64279.7
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.

Advancing to step 8:
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: 64279.71
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.

Advancing to step 9:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 64279.714
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 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 64279.7142
Deduct 14 from 20 and we're left 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.

Step 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 64279.71428
If we take 56 away from 60, we end up 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.

On to step 12:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 64279.714285
Subtracting 35 from 40 leaves us 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.

Advancing to step 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 64279.7142857
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 14:
7 goes into 10 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 64279.71428571
Deduct 7 from 10 and we're left 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 final outcome is 64279.71428571, with a leftover of 3e-09.
