Let's divide 34722 by 21
Our goal is to divide 34722 by 21.

Let's proceed to step 1:
The number 21 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 21

Going ahead to step 2:
21 can be fit into 34 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 21 from 34 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 21

Advancing to step 3:
21 can be fit into 137 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 126 away from 137, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 21

Step 4:
21 goes into 112 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 165.0
Subtract 105 from 112 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 21

Let's proceed to step 5:
If we divide 72 by 21, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 1653.0
Deduct 63 from 72 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 6:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 1653.4
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1653.42
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 1653.428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 1653.4285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 1653.42857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
If we divide 30 by 21, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1653.428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1653.4285714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
If we divide 60 by 21, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 1653.42857142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 1653.42857142 and a remainder of 1.8e-08.
