We look at the division of 22454651 by 405 
We want to figure out the number of times 22454651 can be divided by 405.

Going ahead to step 1:
The number 405 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
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 405

Going ahead to step 2:
405 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 405

Let's proceed to step 3:
405 can be fit into 224 0 times, resulting in a remainder of 224.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 224, we get 224.
Take the next digit (5) from the dividend and append it to 224, then repeat: 2245 / 405

Going ahead to step 4:
The number 405 fits into 2245 5 times, leaving a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2025 from 2245 and we're left with 220.
Take the next digit (4) from the dividend and append it to 220, then repeat: 2204 / 405

Let's proceed to step 5:
405 can be fit into 2204 5 times, resulting in a remainder of 179.
The next digit of our result is 5. 
Result so far: 55.0
The remainder is 179 after subtracting 2025 from 2204.
Bring next digit (6) of the dividend behind the 179 and repeat the process: 1796 / 405

On to step 6:
If we divide 1796 by 405, we get 4 and a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 554.0
The remainder is 176 after subtracting 1620 from 1796.
Include the next digit (5) from the dividend after 176, then repeat: 1765 / 405

Moving on to step 7:
When dividing 1765 by 405, we get 4 with a remainder of 145.
Put 4 as the next digit of the answer. 
Result so far: 5544.0
Deduct 1620 from 1765 and we're left with 145.
Bring next digit (1) of the dividend behind the 145 and repeat the process: 1451 / 405

Moving on to step 8:
1451 divided by 405 is 3 with a remainder of 236.
Use 3 as the next digit of our solution. 
Result so far: 55443.0
Subtracting 1215 from 1451 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
When dividing 2360 by 405, we get 5 with a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 55443.5
The remainder is 335 after subtracting 2025 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 10:
When dividing 3350 by 405, we get 8 with a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 55443.58
The remainder is 110 after subtracting 3240 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
If we divide 1100 by 405, we get 2 and a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 55443.582
Subtracting 810 from 1100 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 12:
The number 405 fits into 2900 7 times, leaving a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 55443.5827
Subtracting 2835 from 2900 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 13:
650 divided by 405 is 1 with a remainder of 245.
The next digit of our result is 1. 
Result so far: 55443.58271
If we subtract 405 from 650, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 14:
When dividing 2450 by 405, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 55443.582716
The remainder is 20 after subtracting 2430 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
405 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 55443.582716
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 16:
If we divide 2000 by 405, we get 4 and a remainder of 380.
Use 4 as the next digit of our solution. 
Result so far: 55443.58271604
Deduct 1620 from 2000 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 55443.58271604 with a remaining 3.8e-07.
