Our goal is to divide 23675317 by 21.

Advancing to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 21

Going ahead to step 2:
If we divide 23 by 21, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 21 from 23 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

On to step 3:
If we divide 26 by 21, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 21 away from 26, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 21

Advancing to step 4:
21 can be fit into 57 2 times, resulting in a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 42 from 57 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 21

Going ahead to step 5:
21 goes into 155 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 1127.0
Deduct 147 from 155 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 21

On to step 6:
21 goes into 83 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 11273.0
Subtract 63 from 83 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 21

Going ahead to step 7:
When dividing 201 by 21, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 112739.0
If we take 189 away from 201, we end up with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 21

Moving on to step 8:
127 divided by 21 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1127396.0
If we take 126 away from 127, 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.

Moving on to step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1127396.0
Deduct 0 from 10 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.

Going ahead to step 10:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1127396.04
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 1127396.047
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.

Going ahead to step 12:
If we divide 130 by 21, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1127396.0476
Subtract 126 from 130 to 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.

Step 13:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1127396.04761
Subtracting 21 from 40 leaves us 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 14:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1127396.047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 15:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1127396.047619
If we subtract 0 from 10, we get 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 16:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1127396.04761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 1127396.04761904 with a balance of 1.6e-08.
