490051 ÷ 5 
We want to figure out the number of times 490051 can be divided by 5.

On to step 1:
5 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 5

On to step 2:
The number 5 fits into 49 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 45 from 49 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 5

Moving on to step 3:
5 can be fit into 40 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 40 away from 40, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 5

Advancing to step 4:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 980.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 5

Advancing to step 5:
5 divided by 5 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 9801.0
Subtract 5 from 5 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 5

Advancing to step 6:
5 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 98010.0
Subtract 0 from 1 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 7:
The number 5 fits into 10 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 98010.2
If we take 10 away from 10, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 98010.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 98010.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 98010.2, with a leftover of 0.0.
