60483770 ÷ 21 
We're looking to find how many times 21 goes into 60483770.

Moving on to step 1:
21 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 21

Moving on to step 2:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 42 from 60 leaves us with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 21

Moving on to step 3:
If we divide 184 by 21, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 168 from 184 to get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 21

Advancing to step 4:
If we divide 168 by 21, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 288.0
If we take 168 away from 168, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 21

Advancing to step 5:
If we divide 3 by 21, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 2880.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 21

Moving on to step 6:
The number 21 fits into 37 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 28801.0
Subtract 21 from 37 to get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 21

Let's proceed to step 7:
When dividing 167 by 21, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 288017.0
Subtracting 147 from 167 leaves us with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 21

On to step 8:
If we divide 200 by 21, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 2880179.0
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.

Step 9:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2880179.5
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2880179.52
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 2880179.523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2880179.5238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2880179.5238
If we take 0 away from 20, we end up 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.

Step 14:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2880179.523809
If we take 189 away from 200, we end up 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.

Let's proceed to step 15:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2880179.5238095
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.

Moving on to step 16:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2880179.52380952
If we take 42 away from 50, we end up 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.

The final outcome is 2880179.52380952, with a leftover of 8e-09.
