We look at the division of 31807086 by 85 
Let's see how many times 85 fits into 31807086.

Advancing to step 1:
If we divide 3 by 85, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 85

Step 2:
85 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 85

Step 3:
When dividing 318 by 85, we get 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 255 from 318 to get 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 85

Going ahead to step 4:
85 can be fit into 630 7 times, resulting in a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Deduct 595 from 630 and we're left with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 85

Step 5:
85 can be fit into 357 4 times, resulting in a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 374.0
The remainder is 17 after subtracting 340 from 357.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 85

On to step 6:
When dividing 170 by 85, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3742.0
Subtracting 170 from 170 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 85

Let's proceed to step 7:
8 divided by 85 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 37420.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 85

On to step 8:
The number 85 fits into 86 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 374201.0
Subtracting 85 from 86 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 85, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 374201.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 85, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 374201.01
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
When dividing 150 by 85, we get 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 374201.011
Subtract 85 from 150 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 374201.011, and the remainder is 0.0065.
