86815716 divided by 404 
We want to divide 86815716 by 404.

Going ahead to step 1:
If we divide 8 by 404, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 404

Advancing to step 2:
404 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 404

Advancing to step 3:
The number 404 fits into 868 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 60 after subtracting 808 from 868.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 404

Let's proceed to step 4:
404 can be fit into 601 1 times, resulting in a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 404 from 601 to get 197.
Include the next digit (5) from the dividend after 197, then repeat: 1975 / 404

Going ahead to step 5:
The number 404 fits into 1975 4 times, leaving a remainder of 359.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Subtracting 1616 from 1975 leaves us with 359.
Bring next digit (7) of the dividend behind the 359 and repeat the process: 3597 / 404

Step 6:
3597 divided by 404 is 8 with a remainder of 365.
Use 8 as the next digit of our solution. 
Result so far: 2148.0
If we subtract 3232 from 3597, we get 365.
Include the next digit (1) from the dividend after 365, then repeat: 3651 / 404

Let's proceed to step 7:
The number 404 fits into 3651 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 21489.0
The remainder is 15 after subtracting 3636 from 3651.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 404

Moving on to step 8:
The number 404 fits into 156 0 times, leaving a remainder of 156.
Record the quotient 0 as the next digit in the result. 
Result so far: 214890.0
The remainder is 156 after subtracting 0 from 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 9:
The number 404 fits into 1560 3 times, leaving a remainder of 348.
The next digit of our result is 3. 
Result so far: 214890.3
Deduct 1212 from 1560 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 10:
404 can be fit into 3480 8 times, resulting in a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 214890.38
If we take 3232 away from 3480, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 11:
404 goes into 2480 6 times with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 214890.386
Subtract 2424 from 2480 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
404 goes into 560 1 times with a remainder of 156.
The next digit of our result is 1. 
Result so far: 214890.3861
Deduct 404 from 560 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 13:
When dividing 1560 by 404, we get 3 with a remainder of 348.
Put 3 as the next digit of the answer. 
Result so far: 214890.38613
Subtract 1212 from 1560 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 14:
404 goes into 3480 8 times with a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 214890.386138
The remainder is 248 after subtracting 3232 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 15:
404 goes into 2480 6 times with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 214890.3861386
Subtract 2424 from 2480 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 16:
560 divided by 404 is 1 with a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 214890.38613861
If we take 404 away from 560, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final outcome is 214890.38613861, with a leftover of 1.56e-07.
