46501859 ÷ 729 
We want to figure out the number of times 46501859 can be divided by 729.

On to step 1:
729 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 729

Going ahead to step 2:
46 divided by 729 is 0 with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 729

Moving on to step 3:
729 can be fit into 465 0 times, resulting in a remainder of 465.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 465 leaves us with 465.
Bring next digit (0) of the dividend behind the 465 and repeat the process: 4650 / 729

On to step 4:
4650 divided by 729 is 6 with a remainder of 276.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 4374 from 4650 and we're left with 276.
Include the next digit (1) from the dividend after 276, then repeat: 2761 / 729

Let's proceed to step 5:
If we divide 2761 by 729, we get 3 and a remainder of 574.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 2187 from 2761 leaves us with 574.
Grab the next digit (8) from the dividend, add it to 574, then carry on: 5748 / 729

Let's proceed to step 6:
If we divide 5748 by 729, we get 7 and a remainder of 645.
Put 7 as the next digit of the answer. 
Result so far: 637.0
Deduct 5103 from 5748 and we're left with 645.
Include the next digit (5) from the dividend after 645, then repeat: 6455 / 729

Advancing to step 7:
729 goes into 6455 8 times with a remainder of 623.
The number 8 becomes the next digit in our result. 
Result so far: 6378.0
Subtracting 5832 from 6455 leaves us with 623.
Take the next digit (9) from the dividend and append it to 623, then repeat: 6239 / 729

Let's proceed to step 8:
If we divide 6239 by 729, we get 8 and a remainder of 407.
The number 8 becomes the next digit in our result. 
Result so far: 63788.0
If we subtract 5832 from 6239, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 9:
When dividing 4070 by 729, we get 5 with a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 63788.5
If we take 3645 away from 4070, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 10:
729 can be fit into 4250 5 times, resulting in a remainder of 605.
Write down 5 as next digit of the result. 
Result so far: 63788.55
If we take 3645 away from 4250, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

The final result is 63788.55 with a remainder of 0.605.
