We look at the division of 143866 by 64 
Let's see how many times 64 fits into 143866.

On to step 1:
1 divided by 64 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 64

Step 2:
The number 64 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 64

Advancing to step 3:
143 divided by 64 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 128 away from 143, we end up with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 64

Step 4:
When dividing 158 by 64, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 128 from 158 to get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 64

Moving on to step 5:
If we divide 306 by 64, we get 4 and a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 224.0
If we take 256 away from 306, we end up with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 64

On to step 6:
When dividing 506 by 64, we get 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 2247.0
If we take 448 away from 506, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
64 goes into 580 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 2247.9
The remainder is 4 after subtracting 576 from 580.
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 8:
40 divided by 64 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2247.9
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
64 can be fit into 400 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 2247.906
Subtracting 384 from 400 leaves us 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 10:
If we divide 160 by 64, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2247.9062
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
If we divide 320 by 64, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2247.90625
Subtracting 320 from 320 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 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2247.90625
The remainder is 0 after subtracting 0 from 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 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2247.90625
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.

Our division results in 2247.90625 with a remaining 0.0.
