Let's divide 349228 by 21
We want to divide 349228 by 21.

Advancing to step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 21

Step 2:
The number 21 fits into 34 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 21 from 34 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 21

Let's proceed to step 3:
The number 21 fits into 139 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 126 from 139 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 21

Advancing to step 4:
21 can be fit into 132 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 166.0
The remainder is 6 after subtracting 126 from 132.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 21

Advancing to step 5:
If we divide 62 by 21, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 1662.0
If we subtract 42 from 62, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 21

Going ahead to step 6:
208 divided by 21 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 16629.0
Deduct 189 from 208 and we're left 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.

Let's proceed to step 7:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 16629.9
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.

Moving on to step 8:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16629.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 16629.904
If we take 84 away from 100, we end up 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.

Step 10:
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: 16629.9047
Deduct 147 from 160 and we're left 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.

Let's proceed to step 11:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 16629.90476
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 12:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 16629.904761
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.

Let's proceed to step 13:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 16629.9047619
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.

Going ahead to step 14:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16629.9047619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 16629.9047619 with a remaining 1e-08.
