Let's divide 190714 by 21
We want to figure out the number of times 190714 can be divided by 21.

Moving on to step 1:
1 divided by 21 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 21

Going ahead to step 2:
When dividing 19 by 21, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 21

Moving on to step 3:
If we divide 190 by 21, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 189 from 190 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 21

Step 4:
If we divide 17 by 21, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtract 0 from 17 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 21

Let's proceed to step 5:
The number 21 fits into 171 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 908.0
Deduct 168 from 171 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 21

Step 6:
34 divided by 21 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 9081.0
Deduct 21 from 34 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.

Step 7:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 9081.6
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.

Advancing to step 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 9081.61
Subtracting 21 from 40 leaves us 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.

On to step 9:
21 goes into 190 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9081.619
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 10:
21 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9081.619
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.

On to step 11:
When dividing 100 by 21, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9081.61904
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.

Advancing to step 12:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9081.619047
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.

Going ahead to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 9081.6190476
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 14:
If we divide 40 by 21, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 9081.61904761
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.

Our division results in 9081.61904761 with a remaining 1.9e-08.
