We're dividing 742333 by 21 
Our goal is to divide 742333 by 21.

Moving on to 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
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 21

Step 2:
74 divided by 21 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 63 from 74 to get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 21

Going ahead to step 3:
21 goes into 112 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 105 from 112 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 21

Let's proceed to step 4:
When dividing 73 by 21, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 353.0
If we subtract 63 from 73, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 21

Step 5:
21 can be fit into 103 4 times, resulting in a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 3534.0
Deduct 84 from 103 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 21

On to step 6:
The number 21 fits into 193 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 35349.0
Deduct 189 from 193 and we're left 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 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 35349.1
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 35349.19
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 35349.19
Subtracting 0 from 10 leaves us 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.

On to step 10:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 35349.1904
Subtract 84 from 100 to 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.

On to step 11:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 35349.19047
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.

On to step 12:
When dividing 130 by 21, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 35349.190476
Deduct 126 from 130 and we're left 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.

Let's proceed to step 13:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 35349.1904761
If we take 21 away from 40, we end up with 19.
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 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 35349.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 35349.19047619, with a leftover of 1e-09.
