64150971 ÷ 100 
We want to divide 64150971 by 100.

Let's proceed to step 1:
If we divide 6 by 100, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 100

On to step 2:
When dividing 64 by 100, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 100

On to step 3:
100 can be fit into 641 6 times, resulting in a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 600 from 641 and we're left with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 100

Let's proceed to step 4:
100 can be fit into 415 4 times, resulting in a remainder of 15.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 400 from 415 to get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 100

Let's proceed to step 5:
100 goes into 150 1 times with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 641.0
If we subtract 100 from 150, we get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 100

Going ahead to step 6:
100 goes into 509 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 6415.0
Subtract 500 from 509 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 100

Going ahead to step 7:
100 can be fit into 97 0 times, resulting in a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 64150.0
The remainder is 97 after subtracting 0 from 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 100

Going ahead to step 8:
100 can be fit into 971 9 times, resulting in a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 641509.0
If we subtract 900 from 971, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
710 divided by 100 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 641509.7
If we take 700 away from 710, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 100 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 641509.71
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
100 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 641509.71
If we subtract 0 from 0, we get 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 12:
100 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 641509.71
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.

The final outcome is 641509.71, with a leftover of 0.0.
