We divide 199885 by 21
Our goal is to divide 199885 by 21.

On to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 21

On to step 2:
21 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 21

Step 3:
199 divided by 21 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 189 away from 199, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 21

Step 4:
If we divide 108 by 21, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtracting 105 from 108 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 21

Advancing to step 5:
The number 21 fits into 38 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 951.0
Deduct 21 from 38 and we're left with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 21

Let's proceed to step 6:
If we divide 175 by 21, we get 8 and a remainder of 7.
The next digit of our result is 8. 
Result so far: 9518.0
If we take 168 away from 175, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 21, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 9518.3
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 21, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 9518.33
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 9518.33, with a leftover of 0.007.
