Let's divide 55659011 by 21
Let's see how many times 21 fits into 55659011.

Going ahead to step 1:
21 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 21

Moving on to step 2:
21 can be fit into 55 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 42 away from 55, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 21

On to step 3:
21 can be fit into 136 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 126 from 136, we get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 21

Step 4:
When dividing 105 by 21, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
Subtracting 105 from 105 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 21

Step 5:
21 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 2650.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 21

Step 6:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 26504.0
The remainder is 6 after subtracting 84 from 90.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 21

Going ahead to step 7:
61 divided by 21 is 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 265042.0
Deduct 42 from 61 and we're left with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 21

Going ahead to step 8:
21 can be fit into 191 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 2650429.0
Subtract 189 from 191 to get 2.
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 9:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2650429.0
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.

Going ahead to step 10:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 2650429.09
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.

Going ahead to step 11:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2650429.095
Subtracting 105 from 110 leaves us 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 12:
21 goes into 50 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2650429.0952
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.

Step 13:
If we divide 80 by 21, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2650429.09523
Subtract 63 from 80 to 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.

Going ahead to step 14:
If we divide 170 by 21, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2650429.095238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2650429.095238
Subtracting 0 from 20 leaves us 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 16:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2650429.09523809
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.

The quotient of the division is 2650429.09523809, and the remainder is 1.1e-08.
