739653 ÷ 21 
We want to divide 739653 by 21.

Step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 21

Step 2:
The number 21 fits into 73 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 63 away from 73, we end up with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 21

Advancing to step 3:
When dividing 109 by 21, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 105 away from 109, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 21

Advancing to step 4:
21 can be fit into 46 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 352.0
The remainder is 4 after subtracting 42 from 46.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 21

Moving on to step 5:
If we divide 45 by 21, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 3522.0
If we take 42 away from 45, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 21

Advancing to step 6:
If we divide 33 by 21, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 35221.0
If we subtract 21 from 33, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 35221.5
Deduct 105 from 120 and we're left 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.

Advancing to step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 35221.57
Subtracting 147 from 150 leaves us with 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 9:
30 divided by 21 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 35221.571
Subtract 21 from 30 to get 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 10:
If we divide 90 by 21, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 35221.5714
The remainder is 6 after subtracting 84 from 90.
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 11:
When dividing 60 by 21, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 35221.57142
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.

Step 12:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 35221.571428
Subtracting 168 from 180 leaves us 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.

Let's proceed to step 13:
When dividing 120 by 21, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 35221.5714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
When dividing 150 by 21, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 35221.57142857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 35221.57142857 with a balance of 3e-09.
