We're dividing 85193889 by 312 
We're looking to find how many times 312 goes into 85193889.

On to step 1:
8 divided by 312 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 312

Advancing to step 2:
When dividing 85 by 312, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 312

Step 3:
312 goes into 851 2 times with a remainder of 227.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 624 from 851 and we're left with 227.
Append the next digit (9) from the dividend to 227 and continue with: 2279 / 312

Moving on to step 4:
The number 312 fits into 2279 7 times, leaving a remainder of 95.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 2184 from 2279 leaves us with 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 312

Advancing to step 5:
When dividing 953 by 312, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 273.0
Subtracting 936 from 953 leaves us with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 312

Moving on to step 6:
When dividing 178 by 312, we get 0 with a remainder of 178.
Write down 0 as next digit of the result. 
Result so far: 2730.0
If we take 0 away from 178, we end up with 178.
Bring next digit (8) of the dividend behind the 178 and repeat the process: 1788 / 312

Advancing to step 7:
312 can be fit into 1788 5 times, resulting in a remainder of 228.
Record the quotient 5 as the next digit in the result. 
Result so far: 27305.0
Subtract 1560 from 1788 to get 228.
Append the next digit (9) from the dividend to 228 and continue with: 2289 / 312

Going ahead to step 8:
If we divide 2289 by 312, we get 7 and a remainder of 105.
The next digit of our result is 7. 
Result so far: 273057.0
Subtracting 2184 from 2289 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
312 goes into 1050 3 times with a remainder of 114.
The next digit of our result is 3. 
Result so far: 273057.3
Subtracting 936 from 1050 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 10:
1140 divided by 312 is 3 with a remainder of 204.
The next digit of our result is 3. 
Result so far: 273057.33
Subtract 936 from 1140 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 273057.33, with a leftover of 0.204.
