We're dividing 23667330 by 21 
We want to figure out the number of times 23667330 can be divided by 21.

Going ahead to step 1:
21 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of 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

On to step 2:
21 can be fit into 23 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 21 from 23 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 21

Let's proceed to step 3:
21 can be fit into 26 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 21 away from 26, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 21

Let's proceed to step 4:
When dividing 56 by 21, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we take 42 away from 56, we end up with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 21

Advancing to step 5:
21 goes into 147 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1127.0
Deduct 147 from 147 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 21

Moving on to step 6:
When dividing 3 by 21, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 11270.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 21

On to step 7:
33 divided by 21 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 112701.0
Deduct 21 from 33 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 21

On to step 8:
21 goes into 120 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1127015.0
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1127015.7
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1127015.71
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1127015.714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
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: 1127015.7142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1127015.71428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
120 divided by 21 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1127015.714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 15:
150 divided by 21 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1127015.7142857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 16:
When dividing 30 by 21, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1127015.71428571
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 1127015.71428571 and a remainder of 9e-09.
