21438707 divided by 546 
We want to divide 21438707 by 546.

Let's proceed to step 1:
When dividing 2 by 546, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 546

On to step 2:
546 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 546

Step 3:
546 goes into 214 0 times with a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Bring next digit (3) of the dividend behind the 214 and repeat the process: 2143 / 546

Going ahead to step 4:
2143 divided by 546 is 3 with a remainder of 505.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1638 from 2143 leaves us with 505.
Take the next digit (8) from the dividend and append it to 505, then repeat: 5058 / 546

On to step 5:
546 can be fit into 5058 9 times, resulting in a remainder of 144.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 4914 away from 5058, we end up with 144.
Include the next digit (7) from the dividend after 144, then repeat: 1447 / 546

Advancing to step 6:
546 can be fit into 1447 2 times, resulting in a remainder of 355.
The next digit of our result is 2. 
Result so far: 392.0
Subtracting 1092 from 1447 leaves us with 355.
Bring next digit (0) of the dividend behind the 355 and repeat the process: 3550 / 546

Moving on to step 7:
546 can be fit into 3550 6 times, resulting in a remainder of 274.
Record the quotient 6 as the next digit in the result. 
Result so far: 3926.0
If we subtract 3276 from 3550, we get 274.
Take the next digit (7) from the dividend and append it to 274, then repeat: 2747 / 546

Advancing to step 8:
2747 divided by 546 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 39265.0
Subtract 2730 from 2747 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 546 fits into 170 0 times, leaving a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 39265.0
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
1700 divided by 546 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 39265.03
If we take 1638 away from 1700, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
546 can be fit into 620 1 times, resulting in a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 39265.031
The remainder is 74 after subtracting 546 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
546 can be fit into 740 1 times, resulting in a remainder of 194.
Write down 1 as next digit of the result. 
Result so far: 39265.0311
If we take 546 away from 740, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

In conclusion, the division gives 39265.0311 with a balance of 0.00194.
