22405437 divided by 21 
We want to divide 22405437 by 21.

Moving on to step 1:
21 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 21

Let's proceed to step 2:
21 goes into 22 1 times with 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.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 21

Step 3:
14 divided by 21 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 21

Advancing to step 4:
21 goes into 140 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 126 from 140 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 21

Let's proceed to step 5:
21 can be fit into 145 6 times, resulting in a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 1066.0
Subtracting 126 from 145 leaves us with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 21

Advancing to step 6:
When dividing 194 by 21, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 10669.0
If we subtract 189 from 194, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 21

Moving on to step 7:
21 can be fit into 53 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 106692.0
Subtracting 42 from 53 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 21

Moving on to step 8:
21 goes into 117 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 1066925.0
The remainder is 12 after subtracting 105 from 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1066925.5
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
150 divided by 21 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1066925.57
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.

Going ahead to step 11:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1066925.571
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.

On to step 12:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1066925.5714
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.

Let's proceed to step 13:
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: 1066925.57142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 1066925.571428
If we subtract 168 from 180, we get 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 15:
When dividing 120 by 21, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1066925.5714285
Subtract 105 from 120 to get 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 16:
150 divided by 21 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1066925.57142857
If we take 147 away from 150, we end up 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.

In conclusion, the division gives 1066925.57142857 with a balance of 3e-09.
