707184 ÷ 21 
Let's see how many times 21 fits into 707184.

Let's proceed to step 1:
21 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 21

Moving on to step 2:
If we divide 70 by 21, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 63 from 70 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 21

On to step 3:
If we divide 77 by 21, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we subtract 63 from 77, we get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 21

Moving on to step 4:
When dividing 141 by 21, we get 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 336.0
The remainder is 15 after subtracting 126 from 141.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 21

Step 5:
If we divide 158 by 21, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 3367.0
Subtract 147 from 158 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 21

Advancing to step 6:
When dividing 114 by 21, we get 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 33675.0
Deduct 105 from 114 and we're left 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.

On to step 7:
90 divided by 21 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 33675.4
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 21, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 33675.42
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 33675.428
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 33675.4285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 33675.42857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 33675.428571
If we take 21 away from 30, we end up 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.

Let's proceed to step 13:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 33675.4285714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 33675.42857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 33675.42857142 and a remainder of 1.8e-08.
