We look at the division of 734233 by 21 
We're looking to find how many times 21 goes into 734233.

Let's proceed to step 1:
7 divided by 21 is 0 with 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.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 21

Let's proceed to step 2:
If we divide 73 by 21, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 10 after subtracting 63 from 73.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 21

Let's proceed to step 3:
The number 21 fits into 104 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 84 from 104, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 21

Let's proceed to step 4:
The number 21 fits into 202 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 349.0
If we subtract 189 from 202, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 21

Step 5:
If we divide 133 by 21, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 3496.0
If we subtract 126 from 133, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 21

On to step 6:
21 can be fit into 73 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 34963.0
If we take 63 away from 73, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 34963.4
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 34963.47
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 34963.476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 34963.4761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 34963.47619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 34963.47619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 21, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 34963.4761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 21, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 34963.47619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 34963.47619047, with a leftover of 1.3e-08.
