We divide 575154 by 21
We want to divide 575154 by 21.

Going ahead to step 1:
21 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 21

Step 2:
57 divided by 21 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 42 from 57 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 21

On to step 3:
If we divide 155 by 21, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 147 from 155 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 21

On to step 4:
81 divided by 21 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 273.0
Subtract 63 from 81 to get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 21

Advancing to step 5:
21 can be fit into 185 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 2738.0
If we subtract 168 from 185, we get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 21

On to step 6:
174 divided by 21 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 27388.0
Deduct 168 from 174 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 21 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 27388.2
Subtracting 42 from 60 leaves us 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.

On to step 8:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 27388.28
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 21, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 27388.285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 27388.2857
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.

Advancing to step 11:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 27388.28571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 27388.285714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 27388.2857142
If we subtract 42 from 60, we 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.

Going ahead to step 14:
If we divide 180 by 21, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 27388.28571428
Subtracting 168 from 180 leaves us 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.

The final outcome is 27388.28571428, with a leftover of 1.2e-08.
