We're dividing 86584348 by 405 
We want to figure out the number of times 86584348 can be divided by 405.

Going ahead to step 1:
The number 405 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 405

Moving on to step 2:
If we divide 86 by 405, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 405

Step 3:
When dividing 865 by 405, we get 2 with a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 810 from 865, we get 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 405

Moving on to step 4:
The number 405 fits into 558 1 times, leaving a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 153 after subtracting 405 from 558.
Append the next digit (4) from the dividend to 153 and continue with: 1534 / 405

Advancing to step 5:
405 goes into 1534 3 times with a remainder of 319.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
If we subtract 1215 from 1534, we get 319.
Append the next digit (3) from the dividend to 319 and continue with: 3193 / 405

On to step 6:
405 can be fit into 3193 7 times, resulting in a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 2137.0
The remainder is 358 after subtracting 2835 from 3193.
Grab the next digit (4) from the dividend, add it to 358, then carry on: 3584 / 405

Step 7:
405 can be fit into 3584 8 times, resulting in a remainder of 344.
The next digit of our result is 8. 
Result so far: 21378.0
Subtract 3240 from 3584 to get 344.
Take the next digit (8) from the dividend and append it to 344, then repeat: 3448 / 405

On to step 8:
405 can be fit into 3448 8 times, resulting in a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 213788.0
Deduct 3240 from 3448 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 9:
2080 divided by 405 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 213788.5
The remainder is 55 after subtracting 2025 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
If we divide 550 by 405, we get 1 and a remainder of 145.
Record the quotient 1 as the next digit in the result. 
Result so far: 213788.51
If we subtract 405 from 550, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 11:
The number 405 fits into 1450 3 times, leaving a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 213788.513
Subtracting 1215 from 1450 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 12:
When dividing 2350 by 405, we get 5 with a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 213788.5135
If we subtract 2025 from 2350, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 13:
3250 divided by 405 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 213788.51358
The remainder is 10 after subtracting 3240 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
When dividing 100 by 405, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 213788.51358
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
If we divide 1000 by 405, we get 2 and a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 213788.5135802
The remainder is 190 after subtracting 810 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
405 can be fit into 1900 4 times, resulting in a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 213788.51358024
Subtracting 1620 from 1900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Our division results in 213788.51358024 with a remaining 2.8e-07.
