We're dividing 429899 by 64 
Let's see how many times 64 fits into 429899.

Advancing to step 1:
The number 64 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 64

Step 2:
When dividing 42 by 64, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 64

Advancing to step 3:
429 divided by 64 is 6 with a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 384 from 429 and we're left with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 64

On to step 4:
When dividing 458 by 64, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we take 448 away from 458, we end up with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 64

Moving on to step 5:
The number 64 fits into 109 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 671.0
Subtract 64 from 109 to get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 64

Moving on to step 6:
If we divide 459 by 64, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 6717.0
Deduct 448 from 459 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
64 can be fit into 110 1 times, resulting in a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 6717.1
The remainder is 46 after subtracting 64 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
64 goes into 460 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 6717.17
Subtract 448 from 460 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 64, we get 1 with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 6717.171
Subtract 64 from 120 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
The number 64 fits into 560 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 6717.1718
The remainder is 48 after subtracting 512 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
480 divided by 64 is 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 6717.17187
If we take 448 away from 480, 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 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6717.171875
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.

Going ahead to step 13:
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: 6717.171875
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 14:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6717.171875
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.

The final result is 6717.171875 with a remainder of 0.0.
