Let's divide 54652207 by 21
We're looking to find how many times 21 goes into 54652207.

Going ahead to step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 21

Advancing to step 2:
The number 21 fits into 54 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 42 from 54, we get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 21

Step 3:
21 goes into 126 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 126 away from 126, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 21

Going ahead to step 4:
When dividing 5 by 21, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 260.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 21

Going ahead to step 5:
The number 21 fits into 52 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2602.0
Subtracting 42 from 52 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 21

Moving on to step 6:
102 divided by 21 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 26024.0
Subtract 84 from 102 to get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 21

Moving on to step 7:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 260248.0
Subtracting 168 from 180 leaves us with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 21

Moving on to step 8:
The number 21 fits into 127 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 2602486.0
The remainder is 1 after subtracting 126 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2602486.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
21 goes into 100 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 2602486.04
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.

Advancing to step 11:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 2602486.047
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.

Advancing to step 12:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2602486.0476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to 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: 2602486.04761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2602486.047619
If we take 189 away from 190, we end up 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.

Let's proceed to step 15:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2602486.047619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 2602486.04761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 2602486.04761904, and the remainder is 1.6e-08.
