22215405 ÷ 406 
Our goal is to divide 22215405 by 406.

Advancing to step 1:
The number 406 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 406

On to step 2:
The number 406 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 406

Let's proceed to step 3:
The number 406 fits into 222 0 times, leaving a remainder of 222.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 222 to get 222.
Append the next digit (1) from the dividend to 222 and continue with: 2221 / 406

Moving on to step 4:
The number 406 fits into 2221 5 times, leaving a remainder of 191.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 2030 from 2221 and we're left with 191.
Bring next digit (5) of the dividend behind the 191 and repeat the process: 1915 / 406

Going ahead to step 5:
406 goes into 1915 4 times with a remainder of 291.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 291 after subtracting 1624 from 1915.
Include the next digit (4) from the dividend after 291, then repeat: 2914 / 406

Moving on to step 6:
406 goes into 2914 7 times with a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 547.0
If we take 2842 away from 2914, we end up with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 406

Moving on to step 7:
The number 406 fits into 720 1 times, leaving a remainder of 314.
Record the quotient 1 as the next digit in the result. 
Result so far: 5471.0
Deduct 406 from 720 and we're left with 314.
Include the next digit (5) from the dividend after 314, then repeat: 3145 / 406

Step 8:
406 can be fit into 3145 7 times, resulting in a remainder of 303.
The next digit of our result is 7. 
Result so far: 54717.0
Deduct 2842 from 3145 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 9:
3030 divided by 406 is 7 with a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 54717.7
If we subtract 2842 from 3030, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
If we divide 1880 by 406, we get 4 and a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 54717.74
Subtract 1624 from 1880 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 11:
406 can be fit into 2560 6 times, resulting in a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 54717.746
Subtracting 2436 from 2560 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 12:
The number 406 fits into 1240 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 54717.7463
Deduct 1218 from 1240 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
When dividing 220 by 406, we get 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 54717.7463
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
2200 divided by 406 is 5 with a remainder of 170.
The next digit of our result is 5. 
Result so far: 54717.746305
Deduct 2030 from 2200 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
The number 406 fits into 1700 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 54717.7463054
If we subtract 1624 from 1700, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 16:
760 divided by 406 is 1 with a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 54717.74630541
If we take 406 away from 760, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

In conclusion, the division gives 54717.74630541 with a balance of 3.54e-07.
