We divide 16405866 by 64
Let's see how many times 64 fits into 16405866.

Step 1:
64 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 64

On to step 2:
64 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 64

Advancing to step 3:
64 can be fit into 164 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 128 from 164 leaves us with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 64

Step 4:
64 can be fit into 360 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 320 from 360 and we're left with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 64

Let's proceed to step 5:
64 can be fit into 405 6 times, resulting in a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
Subtracting 384 from 405 leaves us with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 64

Step 6:
The number 64 fits into 218 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 2563.0
If we subtract 192 from 218, we get 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 64

Step 7:
When dividing 266 by 64, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 25634.0
If we take 256 away from 266, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 64

On to step 8:
64 goes into 106 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 256341.0
Deduct 64 from 106 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
If we divide 420 by 64, we get 6 and a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 256341.6
If we take 384 away from 420, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
If we divide 360 by 64, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 256341.65
Subtract 320 from 360 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
The number 64 fits into 400 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 256341.656
If we take 384 away from 400, we end up 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.

Going ahead to step 12:
160 divided by 64 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 256341.6562
If we take 128 away from 160, we end up 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.

Moving on to step 13:
64 goes into 320 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 256341.65625
The remainder is 0 after subtracting 320 from 320.
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 14:
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: 256341.65625
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.

Let's proceed to step 15:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 256341.65625
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.

The quotient of the division is 256341.65625, and the remainder is 0.0.
