We're dividing 651636 by 64 
We want to divide 651636 by 64.

Step 1:
6 divided by 64 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 64

Going ahead to step 2:
The number 64 fits into 65 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 64 from 65 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 64

Advancing to step 3:
64 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 64

Step 4:
64 goes into 116 1 times with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtracting 64 from 116 leaves us with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 64

Going ahead to step 5:
64 can be fit into 523 8 times, resulting in a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 1018.0
Subtract 512 from 523 to get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 64

Advancing to step 6:
116 divided by 64 is 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 10181.0
If we subtract 64 from 116, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
If we divide 520 by 64, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 10181.8
Subtract 512 from 520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 10181.81
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10181.812
Subtracting 128 from 160 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10181.8125
Subtract 320 from 320 to 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.

Going ahead to step 11:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10181.8125
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.

Advancing to step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10181.8125
Subtract 0 from 0 to 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.

After the division, we end up with 10181.8125 and a remainder of 0.0.
