We look at the division of 85509092 by 407 
Let's see how many times 407 fits into 85509092.

Going ahead to step 1:
The number 407 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 407

Going ahead to step 2:
407 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 407

On to step 3:
When dividing 855 by 407, we get 2 with a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 814 from 855 leaves us with 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 407

Step 4:
407 can be fit into 410 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 407 from 410 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 407

Step 5:
The number 407 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 210.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 407

Step 6:
When dividing 390 by 407, we get 0 with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 2100.0
Deduct 0 from 390 and we're left with 390.
Fetch the next digit (9) from the dividend, attach it to 390 and continue: 3909 / 407

Moving on to step 7:
407 goes into 3909 9 times with a remainder of 246.
Record the quotient 9 as the next digit in the result. 
Result so far: 21009.0
Deduct 3663 from 3909 and we're left with 246.
Append the next digit (2) from the dividend to 246 and continue with: 2462 / 407

Going ahead to step 8:
407 goes into 2462 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 210096.0
If we subtract 2442 from 2462, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
407 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 210096.0
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 10:
407 goes into 2000 4 times with a remainder of 372.
The next digit of our result is 4. 
Result so far: 210096.04
Subtracting 1628 from 2000 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 11:
407 can be fit into 3720 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 210096.049
If we subtract 3663 from 3720, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
407 can be fit into 570 1 times, resulting in a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 210096.0491
Subtract 407 from 570 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 13:
When dividing 1630 by 407, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 210096.04914
If we take 1628 away from 1630, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
407 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 210096.04914
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
407 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 210096.04914
If we take 0 away from 200, we end up 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.

After the division, we end up with 210096.04914 and a remainder of 2e-06.
