Let's divide 337484 by 21
We want to figure out the number of times 337484 can be divided by 21.

Step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 21

Going ahead to step 2:
If we divide 33 by 21, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 21 from 33 to get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 21

Advancing to step 3:
When dividing 127 by 21, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 126 from 127, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 21

Let's proceed to step 4:
When dividing 14 by 21, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 21

Let's proceed to step 5:
The number 21 fits into 148 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 1607.0
Deduct 147 from 148 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

On to step 6:
14 divided by 21 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 16070.0
If we take 0 away from 14, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 21, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 16070.6
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 21, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 16070.66
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 16070.66, with a leftover of 0.014.
