We look at the division of 739770 by 21 
Our goal is to divide 739770 by 21.

Let's proceed to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 21

Let's proceed to step 2:
21 can be fit into 73 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 63 from 73 to get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 21

Let's proceed to step 3:
21 can be fit into 109 5 times, resulting in 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 (7) from the dividend after 4, then repeat: 47 / 21

Step 4:
The number 21 fits into 47 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
If we subtract 42 from 47, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 21

Let's proceed to step 5:
21 can be fit into 57 2 times, resulting in a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 3522.0
Subtracting 42 from 57 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 21

Advancing to step 6:
150 divided by 21 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 35227.0
If we take 147 away from 150, we end up 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 7:
When dividing 30 by 21, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 35227.1
Subtracting 21 from 30 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.

Step 8:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 35227.14
If we take 84 away from 90, we end up 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.

Going ahead to step 9:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 35227.142
If we take 42 away from 60, we end up 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 10:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 35227.1428
If we subtract 168 from 180, 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.

Going ahead to step 11:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 35227.14285
If we subtract 105 from 120, we 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.

On to step 12:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 35227.142857
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.

Advancing to step 13:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 35227.1428571
If we subtract 21 from 30, we 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.

Moving on to step 14:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 35227.14285714
If we take 84 away from 90, we end up 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.

The final outcome is 35227.14285714, with a leftover of 6e-09.
