87824973 ÷ 405 
We're looking to find how many times 405 goes into 87824973.

Moving on to step 1:
If we divide 8 by 405, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 405

On to step 2:
If we divide 87 by 405, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 405

On to step 3:
878 divided by 405 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 810 from 878 leaves us with 68.
Include the next digit (2) from the dividend after 68, then repeat: 682 / 405

Advancing to step 4:
405 goes into 682 1 times with a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 405 from 682 and we're left with 277.
Grab the next digit (4) from the dividend, add it to 277, then carry on: 2774 / 405

Step 5:
When dividing 2774 by 405, we get 6 with a remainder of 344.
The next digit of our result is 6. 
Result so far: 216.0
The remainder is 344 after subtracting 2430 from 2774.
Fetch the next digit (9) from the dividend, attach it to 344 and continue: 3449 / 405

Going ahead to step 6:
If we divide 3449 by 405, we get 8 and a remainder of 209.
Record the quotient 8 as the next digit in the result. 
Result so far: 2168.0
Deduct 3240 from 3449 and we're left with 209.
Take the next digit (7) from the dividend and append it to 209, then repeat: 2097 / 405

On to step 7:
405 goes into 2097 5 times with a remainder of 72.
Record the quotient 5 as the next digit in the result. 
Result so far: 21685.0
The remainder is 72 after subtracting 2025 from 2097.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 405

Moving on to step 8:
405 can be fit into 723 1 times, resulting in a remainder of 318.
The number 1 becomes the next digit in our result. 
Result so far: 216851.0
Subtracting 405 from 723 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 9:
405 goes into 3180 7 times with a remainder of 345.
Write down 7 as next digit of the result. 
Result so far: 216851.7
The remainder is 345 after subtracting 2835 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 10:
3450 divided by 405 is 8 with a remainder of 210.
Write down 8 as next digit of the result. 
Result so far: 216851.78
Subtract 3240 from 3450 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 11:
405 can be fit into 2100 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 216851.785
Deduct 2025 from 2100 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
The number 405 fits into 750 1 times, leaving a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 216851.7851
If we subtract 405 from 750, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Going ahead to step 13:
405 goes into 3450 8 times with a remainder of 210.
Record the quotient 8 as the next digit in the result. 
Result so far: 216851.78518
The remainder is 210 after subtracting 3240 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 14:
When dividing 2100 by 405, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 216851.785185
If we subtract 2025 from 2100, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 15:
The number 405 fits into 750 1 times, leaving a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 216851.7851851
Subtracting 405 from 750 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 16:
If we divide 3450 by 405, we get 8 and a remainder of 210.
The next digit of our result is 8. 
Result so far: 216851.78518518
Subtract 3240 from 3450 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 216851.78518518 with a remainder of 2.1e-07.
