354729 divided by 20 
We're looking to find how many times 20 goes into 354729.

Step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Advancing to step 2:
35 divided by 20 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 35, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 20

Moving on to step 3:
The number 20 fits into 154 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 140 from 154 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 20

Moving on to step 4:
20 goes into 147 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 177.0
The remainder is 7 after subtracting 140 from 147.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

On to step 5:
When dividing 72 by 20, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1773.0
If we subtract 60 from 72, we get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 20

Advancing to step 6:
129 divided by 20 is 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 17736.0
Subtracting 120 from 129 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 20, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 17736.4
Subtract 80 from 90 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17736.45
If we subtract 100 from 100, 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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17736.45
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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 17736.45
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.

In conclusion, the division gives 17736.45 with a balance of 0.0.
