86018519 divided by 405 
Our goal is to divide 86018519 by 405.

Advancing to step 1:
The number 405 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 405

Step 2:
405 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 405

Advancing to step 3:
860 divided by 405 is 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 810 from 860 and we're left with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 405

Let's proceed to step 4:
When dividing 501 by 405, we get 1 with a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 96 after subtracting 405 from 501.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 405

Advancing to step 5:
405 goes into 968 2 times with a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Deduct 810 from 968 and we're left with 158.
Take the next digit (5) from the dividend and append it to 158, then repeat: 1585 / 405

Going ahead to step 6:
If we divide 1585 by 405, we get 3 and a remainder of 370.
The number 3 becomes the next digit in our result. 
Result so far: 2123.0
Deduct 1215 from 1585 and we're left with 370.
Grab the next digit (1) from the dividend, add it to 370, then carry on: 3701 / 405

Going ahead to step 7:
If we divide 3701 by 405, we get 9 and a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 21239.0
Subtracting 3645 from 3701 leaves us with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 405

Step 8:
569 divided by 405 is 1 with a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 212391.0
Subtracting 405 from 569 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 9:
405 goes into 1640 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 212391.4
If we take 1620 away from 1640, we end up 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.

Let's proceed to step 10:
405 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 212391.4
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
405 can be fit into 2000 4 times, resulting in a remainder of 380.
Record the quotient 4 as the next digit in the result. 
Result so far: 212391.404
If we subtract 1620 from 2000, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 12:
The number 405 fits into 3800 9 times, leaving a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 212391.4049
Subtract 3645 from 3800 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 13:
405 can be fit into 1550 3 times, resulting in a remainder of 335.
Write down 3 as next digit of the result. 
Result so far: 212391.40493
Deduct 1215 from 1550 and we're left 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.

Step 14:
If we divide 3350 by 405, we get 8 and a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 212391.404938
If we subtract 3240 from 3350, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
If we divide 1100 by 405, we get 2 and a remainder of 290.
The next digit of our result is 2. 
Result so far: 212391.4049382
Subtract 810 from 1100 to 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.

Going ahead to step 16:
2900 divided by 405 is 7 with a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 212391.40493827
Subtract 2835 from 2900 to 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.

The quotient of the division is 212391.40493827, and the remainder is 6.5e-08.
