We divide 85310 by 31
Let's see how many times 31 fits into 85310.

Moving on 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
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 31

On to step 2:
85 divided by 31 is 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 23 after subtracting 62 from 85.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 31

Moving on to step 3:
31 can be fit into 233 7 times, resulting in a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 217 away from 233, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 31

Going ahead to step 4:
When dividing 161 by 31, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 275.0
If we take 155 away from 161, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 31

Advancing to step 5:
When dividing 60 by 31, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 2751.0
Deduct 31 from 60 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 6:
290 divided by 31 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 2751.9
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 2751.93
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
31 goes into 170 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2751.935
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
31 goes into 150 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 2751.9354
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
When dividing 260 by 31, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 2751.93548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
120 divided by 31 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 2751.935483
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
31 goes into 270 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 2751.9354838
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
When dividing 220 by 31, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2751.93548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 2751.93548387 with a remainder of 3e-09.
