We divide 207859 by 21
Our goal is to divide 207859 by 21.

Moving on to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 21

Moving on to step 2:
20 divided by 21 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 21

Going ahead to step 3:
21 can be fit into 207 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 189 from 207 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 21

Step 4:
21 can be fit into 188 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 98.0
The remainder is 20 after subtracting 168 from 188.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 21

Step 5:
When dividing 205 by 21, we get 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 989.0
The remainder is 16 after subtracting 189 from 205.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 21

Going ahead to step 6:
If we divide 169 by 21, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 9898.0
The remainder is 1 after subtracting 168 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9898.0
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.

Advancing to step 8:
If we divide 100 by 21, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 9898.04
The remainder is 16 after subtracting 84 from 100.
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 9:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 9898.047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 9898.0476
Subtract 126 from 130 to get 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 11:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 9898.04761
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.

Going ahead to step 12:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9898.047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 9898.047619
If we subtract 0 from 10, we 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.

On to step 14:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 9898.04761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 9898.04761904 with a balance of 1.6e-08.
