22631869 ÷ 21 
We want to figure out the number of times 22631869 can be divided by 21.

Step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

Step 2:
The number 21 fits into 22 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 21 from 22, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Moving on to step 3:
The number 21 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 16 after subtracting 0 from 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 21

Moving on to step 4:
163 divided by 21 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 147 away from 163, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 21

On to step 5:
If we divide 161 by 21, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 1077.0
The remainder is 14 after subtracting 147 from 161.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 21

Let's proceed to step 6:
21 goes into 148 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 10777.0
The remainder is 1 after subtracting 147 from 148.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 21

Step 7:
The number 21 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 107770.0
Subtract 0 from 16 to get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 21

Step 8:
21 can be fit into 169 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1077708.0
Subtracting 168 from 169 leaves us 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.

Step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1077708.0
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.

Going ahead to step 10:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1077708.04
If we take 84 away from 100, we end up 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.

Let's proceed to step 11:
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: 1077708.047
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.

Step 12:
21 goes into 130 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1077708.0476
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.

Step 13:
21 goes into 40 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1077708.04761
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:
190 divided by 21 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1077708.047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 15:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1077708.047619
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.

Step 16:
100 divided by 21 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1077708.04761904
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.

The final result is 1077708.04761904 with a remainder of 1.6e-08.
