60228725 ÷ 21 
Our goal is to divide 60228725 by 21.

Going ahead to step 1:
6 divided by 21 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 21

Moving on to step 2:
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: 2.0
Deduct 42 from 60 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 21

On to step 3:
When dividing 182 by 21, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 168 from 182, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 21

Let's proceed to step 4:
142 divided by 21 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 286.0
Subtracting 126 from 142 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 21

Let's proceed to step 5:
21 goes into 168 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2868.0
Subtracting 168 from 168 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 21

Going ahead to step 6:
7 divided by 21 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 28680.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 21

Moving on to step 7:
21 can be fit into 72 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 286803.0
If we take 63 away from 72, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 21

Advancing to step 8:
When dividing 95 by 21, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 2868034.0
Subtract 84 from 95 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2868034.5
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2868034.52
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 2868034.523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2868034.5238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
If we divide 20 by 21, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2868034.5238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 2868034.523809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 15:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2868034.5238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 16:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 2868034.52380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 2868034.52380952 and a remainder of 8e-09.
