We look at the division of 85220 by 31 
We want to figure out the number of times 85220 can be divided by 31.

Going ahead to step 1:
31 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 31

Let's proceed to step 2:
85 divided by 31 is 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 62 from 85 leaves us with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 31

Advancing to step 3:
When dividing 232 by 31, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 15 after subtracting 217 from 232.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 31

Going ahead to step 4:
When dividing 152 by 31, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 274.0
Deduct 124 from 152 and we're left with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 31

Let's proceed to step 5:
When dividing 280 by 31, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2749.0
Deduct 279 from 280 and we're left 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.

Step 6:
10 divided by 31 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2749.0
Deduct 0 from 10 and we're left 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.

Advancing to step 7:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 2749.03
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
If we divide 70 by 31, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2749.032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 31 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2749.0322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 2749.0322 and a remainder of 0.00018.
