Let's divide 566737 by 21
We want to figure out the number of times 566737 can be divided by 21.

Step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 21

Let's proceed to step 2:
When dividing 56 by 21, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 42 from 56 and we're left with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 21

Moving on to step 3:
If we divide 146 by 21, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 126 from 146 to get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 21

Let's proceed to step 4:
When dividing 207 by 21, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
The remainder is 18 after subtracting 189 from 207.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 21

Moving on to step 5:
21 goes into 183 8 times with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 2698.0
Deduct 168 from 183 and we're left with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 21

Moving on to step 6:
157 divided by 21 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 26987.0
Deduct 147 from 157 and we're left 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 7:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 26987.4
Subtracting 84 from 100 leaves us 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.

Step 8:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 26987.47
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
21 goes into 130 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 26987.476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 26987.4761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
When dividing 190 by 21, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 26987.47619
Deduct 189 from 190 and we're left 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.

Going ahead to step 12:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 26987.47619
Subtracting 0 from 10 leaves us 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.

Going ahead to step 13:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 26987.4761904
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.

On to step 14:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 26987.47619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 26987.47619047 with a remainder of 1.3e-08.
