We're dividing 731803 by 21 
Let's see how many times 21 fits into 731803.

Going ahead 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
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

Let's proceed to step 2:
The number 21 fits into 73 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 10 after subtracting 63 from 73.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 21

Advancing to step 3:
21 can be fit into 101 4 times, resulting in a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtracting 84 from 101 leaves us with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 21

Going ahead to step 4:
The number 21 fits into 178 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 348.0
Subtract 168 from 178 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 21

Advancing to step 5:
When dividing 100 by 21, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 3484.0
The remainder is 16 after subtracting 84 from 100.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 21

Going ahead to step 6:
The number 21 fits into 163 7 times, leaving a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 34847.0
If we subtract 147 from 163, 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.

On to step 7:
21 goes into 160 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 34847.7
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.

Step 8:
If we divide 130 by 21, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 34847.76
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.

Moving on to step 9:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 34847.761
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.

Step 10:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 34847.7619
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 11:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 34847.7619
If we take 0 away from 10, 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 12:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 34847.761904
Subtracting 84 from 100 leaves us with 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 13:
When dividing 160 by 21, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 34847.7619047
If we subtract 147 from 160, we 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.

Moving on to step 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 34847.76190476
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.

After the division, we end up with 34847.76190476 and a remainder of 4e-09.
