63450999 divided by 5 
Let's see how many times 5 fits into 63450999.

Let's proceed to step 1:
The number 5 fits into 6 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 5 from 6 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 5

Step 2:
5 can be fit into 13 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 10 away from 13, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 5

Let's proceed to step 3:
34 divided by 5 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 126.0
Deduct 30 from 34 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 5

Let's proceed to step 4:
5 can be fit into 45 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1269.0
Subtracting 45 from 45 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 5

Advancing to step 5:
When dividing 0 by 5, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12690.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 5

Step 6:
If we divide 9 by 5, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 126901.0
If we subtract 5 from 9, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 5

Step 7:
5 can be fit into 49 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1269019.0
Deduct 45 from 49 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 5

Step 8:
49 divided by 5 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 12690199.0
Deduct 45 from 49 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.

Let's proceed to step 9:
If we divide 40 by 5, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 12690199.8
If we take 40 away from 40, 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.

Going ahead to step 10:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12690199.8
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 11:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12690199.8
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.

After the division, we end up with 12690199.8 and a remainder of 0.0.
