Let's divide 575194 by 21
Our goal is to divide 575194 by 21.

Advancing to step 1:
The number 21 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 21

Going ahead to step 2:
When dividing 57 by 21, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 42 from 57 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 21

Moving on to step 3:
21 goes into 155 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 8 after subtracting 147 from 155.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 21

Step 4:
If we divide 81 by 21, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 273.0
If we take 63 away from 81, we end up with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 21

On to step 5:
If we divide 189 by 21, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 2739.0
Deduct 189 from 189 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 21

Going ahead to step 6:
21 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 27390.0
Subtracting 0 from 4 leaves us 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.

Step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 27390.1
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.

On to step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 27390.19
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.

On to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 27390.19
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.

Going ahead to step 10:
100 divided by 21 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 27390.1904
Deduct 84 from 100 and we're left 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.

On to step 11:
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: 27390.19047
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.

Going ahead to step 12:
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: 27390.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
40 divided by 21 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 27390.1904761
Subtract 21 from 40 to 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.

Moving on to step 14:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 27390.19047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 27390.19047619 with a balance of 1e-09.
