3545919 divided by 729 
We want to figure out the number of times 3545919 can be divided by 729.

Step 1:
3 divided by 729 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 729

Going ahead to step 2:
729 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 729

Advancing to step 3:
729 goes into 354 0 times with a remainder of 354.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 354, we get 354.
Take the next digit (5) from the dividend and append it to 354, then repeat: 3545 / 729

Advancing to step 4:
729 can be fit into 3545 4 times, resulting in a remainder of 629.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2916 away from 3545, we end up with 629.
Bring next digit (9) of the dividend behind the 629 and repeat the process: 6299 / 729

Let's proceed to step 5:
The number 729 fits into 6299 8 times, leaving a remainder of 467.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 5832 from 6299 and we're left with 467.
Include the next digit (1) from the dividend after 467, then repeat: 4671 / 729

Advancing to step 6:
The number 729 fits into 4671 6 times, leaving a remainder of 297.
Record the quotient 6 as the next digit in the result. 
Result so far: 486.0
The remainder is 297 after subtracting 4374 from 4671.
Append the next digit (9) from the dividend to 297 and continue with: 2979 / 729

Going ahead to step 7:
729 goes into 2979 4 times with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 4864.0
Subtract 2916 from 2979 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 8:
630 divided by 729 is 0 with a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 4864.0
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 9:
729 can be fit into 6300 8 times, resulting in a remainder of 468.
The number 8 becomes the next digit in our result. 
Result so far: 4864.08
Subtracting 5832 from 6300 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 10:
The number 729 fits into 4680 6 times, leaving a remainder of 306.
The number 6 becomes the next digit in our result. 
Result so far: 4864.086
If we subtract 4374 from 4680, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 11:
729 can be fit into 3060 4 times, resulting in a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 4864.0864
Subtract 2916 from 3060 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 12:
729 can be fit into 1440 1 times, resulting in a remainder of 711.
Use 1 as the next digit of our solution. 
Result so far: 4864.08641
Deduct 729 from 1440 and we're left with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

On to step 13:
If we divide 7110 by 729, we get 9 and a remainder of 549.
Put 9 as the next digit of the answer. 
Result so far: 4864.086419
Subtract 6561 from 7110 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 14:
The number 729 fits into 5490 7 times, leaving a remainder of 387.
Record the quotient 7 as the next digit in the result. 
Result so far: 4864.0864197
The remainder is 387 after subtracting 5103 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Let's proceed to step 15:
729 goes into 3870 5 times with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 4864.08641975
If we subtract 3645 from 3870, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 4864.08641975, and the remainder is 2.25e-07.
