Let's divide 3589850 by 405
We're looking to find how many times 405 goes into 3589850.

Moving on to step 1:
If we divide 3 by 405, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 405

Moving on to step 2:
The number 405 fits into 35 0 times, leaving a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 405

Advancing to step 3:
405 goes into 358 0 times with a remainder of 358.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 358 leaves us with 358.
Include the next digit (9) from the dividend after 358, then repeat: 3589 / 405

On to step 4:
If we divide 3589 by 405, we get 8 and a remainder of 349.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 3240 from 3589, we get 349.
Grab the next digit (8) from the dividend, add it to 349, then carry on: 3498 / 405

Let's proceed to step 5:
405 goes into 3498 8 times with a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 3240 from 3498 leaves us with 258.
Fetch the next digit (5) from the dividend, attach it to 258 and continue: 2585 / 405

Step 6:
405 goes into 2585 6 times with a remainder of 155.
Put 6 as the next digit of the answer. 
Result so far: 886.0
If we take 2430 away from 2585, we end up with 155.
Take the next digit (0) from the dividend and append it to 155, then repeat: 1550 / 405

Let's proceed to step 7:
When dividing 1550 by 405, we get 3 with a remainder of 335.
Record the quotient 3 as the next digit in the result. 
Result so far: 8863.0
Subtracting 1215 from 1550 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 8:
If we divide 3350 by 405, we get 8 and a remainder of 110.
Put 8 as the next digit of the answer. 
Result so far: 8863.8
Deduct 3240 from 3350 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 9:
When dividing 1100 by 405, we get 2 with a remainder of 290.
Write down 2 as next digit of the result. 
Result so far: 8863.82
If we subtract 810 from 1100, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
405 can be fit into 2900 7 times, resulting in a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 8863.827
If we subtract 2835 from 2900, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
When dividing 650 by 405, we get 1 with a remainder of 245.
The next digit of our result is 1. 
Result so far: 8863.8271
The remainder is 245 after subtracting 405 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 12:
405 can be fit into 2450 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 8863.82716
Deduct 2430 from 2450 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
The number 405 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 8863.82716
Deduct 0 from 200 and we're left 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.

Going ahead to step 14:
When dividing 2000 by 405, we get 4 with a remainder of 380.
Write down 4 as next digit of the result. 
Result so far: 8863.8271604
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.

Advancing to step 15:
405 can be fit into 3800 9 times, resulting in a remainder of 155.
Write down 9 as next digit of the result. 
Result so far: 8863.82716049
Deduct 3645 from 3800 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final outcome is 8863.82716049, with a leftover of 1.55e-07.
