399954 ÷ 64 
We want to figure out the number of times 399954 can be divided by 64.

Let's proceed to step 1:
If we divide 3 by 64, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 64

Going ahead to step 2:
64 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 64

Going ahead to step 3:
64 goes into 399 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 384 from 399, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 64

Let's proceed to step 4:
The number 64 fits into 159 2 times, leaving a remainder of 31.
The next digit of our result is 2. 
Result so far: 62.0
Deduct 128 from 159 and we're left with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 64

Going ahead to step 5:
64 goes into 315 4 times with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 624.0
Deduct 256 from 315 and we're left with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 64

Advancing to step 6:
If we divide 594 by 64, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 6249.0
If we take 576 away from 594, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 64 is 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 6249.2
Subtracting 128 from 180 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
64 can be fit into 520 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 6249.28
Subtracting 512 from 520 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
64 can be fit into 80 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 6249.281
If we take 64 away from 80, 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 10:
160 divided by 64 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 6249.2812
The remainder is 32 after subtracting 128 from 160.
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 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6249.28125
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:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6249.28125
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.

Going ahead to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6249.28125
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.

In conclusion, the division gives 6249.28125 with a balance of 0.0.
