Let's divide 85130309 by 392
Our goal is to divide 85130309 by 392.

Moving on to step 1:
392 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 392

Step 2:
85 divided by 392 is 0 with 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.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 392

Let's proceed to step 3:
392 can be fit into 851 2 times, resulting in a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 784 from 851 to get 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 392

Advancing to step 4:
When dividing 673 by 392, we get 1 with a remainder of 281.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 392 from 673 and we're left with 281.
Fetch the next digit (0) from the dividend, attach it to 281 and continue: 2810 / 392

Moving on to step 5:
2810 divided by 392 is 7 with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 217.0
If we take 2744 away from 2810, we end up with 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 392

Step 6:
392 can be fit into 663 1 times, resulting in a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 2171.0
Subtract 392 from 663 to get 271.
Append the next digit (0) from the dividend to 271 and continue with: 2710 / 392

Step 7:
392 goes into 2710 6 times with a remainder of 358.
Put 6 as the next digit of the answer. 
Result so far: 21716.0
If we take 2352 away from 2710, we end up with 358.
Append the next digit (9) from the dividend to 358 and continue with: 3589 / 392

Let's proceed to step 8:
The number 392 fits into 3589 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 217169.0
Subtracting 3528 from 3589 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
When dividing 610 by 392, we get 1 with a remainder of 218.
The number 1 becomes the next digit in our result. 
Result so far: 217169.1
If we subtract 392 from 610, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
392 can be fit into 2180 5 times, resulting in a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 217169.15
If we take 1960 away from 2180, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
392 can be fit into 2200 5 times, resulting in a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 217169.155
Subtract 1960 from 2200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 217169.155 and a remainder of 0.024.
