430173 ÷ 64 
We want to divide 430173 by 64.

Let's proceed to step 1:
When dividing 4 by 64, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 64

Moving on to step 2:
When dividing 43 by 64, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 64

Advancing to step 3:
If we divide 430 by 64, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 384 from 430 to get 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 64

Moving on to step 4:
If we divide 461 by 64, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtract 448 from 461 to get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 64

Step 5:
64 goes into 137 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 672.0
If we take 128 away from 137, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 64

Going ahead to step 6:
64 can be fit into 93 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 6721.0
Deduct 64 from 93 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
If we divide 290 by 64, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 6721.4
The remainder is 34 after subtracting 256 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 64, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 6721.45
If we take 320 away from 340, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
200 divided by 64 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 6721.453
Subtracting 192 from 200 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 10:
If we divide 80 by 64, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 6721.4531
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 6721.45312
Deduct 128 from 160 and we're left 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 12:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6721.453125
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 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: 6721.453125
Subtracting 0 from 0 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.

Advancing to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6721.453125
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.

The quotient of the division is 6721.453125, and the remainder is 0.0.
