Let's divide 705149 by 21
Our goal is to divide 705149 by 21.

Step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 21

Moving on to step 2:
When dividing 70 by 21, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 7 after subtracting 63 from 70.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 21

Step 3:
When dividing 75 by 21, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Deduct 63 from 75 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 21

Step 4:
The number 21 fits into 121 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
Subtracting 105 from 121 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 21

On to step 5:
The number 21 fits into 164 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 3357.0
The remainder is 17 after subtracting 147 from 164.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 21

Moving on to step 6:
21 can be fit into 179 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 33578.0
Subtract 168 from 179 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 33578.5
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 33578.52
Subtracting 42 from 50 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.

On to step 9:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 33578.523
If we take 63 away from 80, we end up with 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 10:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 33578.5238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 33578.5238
Subtract 0 from 20 to get 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 12:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 33578.523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 33578.5238095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 33578.52380952
If we take 42 away from 50, we end up 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.

In conclusion, the division gives 33578.52380952 with a balance of 8e-09.
