We look at the division of 53000447 by 405 
We want to figure out the number of times 53000447 can be divided by 405.

On to step 1:
5 divided by 405 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 405

Advancing to step 2:
53 divided by 405 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 405

Going ahead to step 3:
The number 405 fits into 530 1 times, leaving a remainder of 125.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 405 from 530 and we're left with 125.
Take the next digit (0) from the dividend and append it to 125, then repeat: 1250 / 405

Step 4:
The number 405 fits into 1250 3 times, leaving a remainder of 35.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 35 after subtracting 1215 from 1250.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 405

On to step 5:
405 can be fit into 350 0 times, resulting in a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtract 0 from 350 to get 350.
Grab the next digit (4) from the dividend, add it to 350, then carry on: 3504 / 405

Advancing to step 6:
405 goes into 3504 8 times with a remainder of 264.
Record the quotient 8 as the next digit in the result. 
Result so far: 1308.0
Subtract 3240 from 3504 to get 264.
Bring next digit (4) of the dividend behind the 264 and repeat the process: 2644 / 405

Going ahead to step 7:
2644 divided by 405 is 6 with a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 13086.0
Subtract 2430 from 2644 to get 214.
Grab the next digit (7) from the dividend, add it to 214, then carry on: 2147 / 405

Let's proceed to step 8:
405 can be fit into 2147 5 times, resulting in a remainder of 122.
Write down 5 as next digit of the result. 
Result so far: 130865.0
Subtract 2025 from 2147 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 9:
The number 405 fits into 1220 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 130865.3
Subtract 1215 from 1220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
405 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 130865.3
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
When dividing 500 by 405, we get 1 with a remainder of 95.
The next digit of our result is 1. 
Result so far: 130865.301
If we take 405 away from 500, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
When dividing 950 by 405, we get 2 with a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 130865.3012
Subtract 810 from 950 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
1400 divided by 405 is 3 with a remainder of 185.
The next digit of our result is 3. 
Result so far: 130865.30123
If we subtract 1215 from 1400, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 14:
When dividing 1850 by 405, we get 4 with a remainder of 230.
The number 4 becomes the next digit in our result. 
Result so far: 130865.301234
The remainder is 230 after subtracting 1620 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 15:
When dividing 2300 by 405, we get 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 130865.3012345
Deduct 2025 from 2300 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 16:
405 can be fit into 2750 6 times, resulting in a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 130865.30123456
Deduct 2430 from 2750 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 130865.30123456, with a leftover of 3.2e-07.
