We're dividing 87403358 by 311 
We're looking to find how many times 311 goes into 87403358.

Advancing to step 1:
When dividing 8 by 311, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 311

Step 2:
If we divide 87 by 311, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 311

Step 3:
When dividing 874 by 311, we get 2 with a remainder of 252.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 622 from 874 and we're left with 252.
Include the next digit (0) from the dividend after 252, then repeat: 2520 / 311

Going ahead to step 4:
When dividing 2520 by 311, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 2488 from 2520, we get 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 311

Going ahead to step 5:
The number 311 fits into 323 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 281.0
Deduct 311 from 323 and we're left with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 311

Advancing to step 6:
311 goes into 123 0 times with a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 2810.0
Deduct 0 from 123 and we're left with 123.
Take the next digit (5) from the dividend and append it to 123, then repeat: 1235 / 311

Step 7:
The number 311 fits into 1235 3 times, leaving a remainder of 302.
Put 3 as the next digit of the answer. 
Result so far: 28103.0
The remainder is 302 after subtracting 933 from 1235.
Fetch the next digit (8) from the dividend, attach it to 302 and continue: 3028 / 311

Step 8:
The number 311 fits into 3028 9 times, leaving a remainder of 229.
Record the quotient 9 as the next digit in the result. 
Result so far: 281039.0
Deduct 2799 from 3028 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 9:
The number 311 fits into 2290 7 times, leaving a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 281039.7
If we take 2177 away from 2290, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 10:
When dividing 1130 by 311, we get 3 with a remainder of 197.
The next digit of our result is 3. 
Result so far: 281039.73
Subtract 933 from 1130 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 11:
311 goes into 1970 6 times with a remainder of 104.
The next digit of our result is 6. 
Result so far: 281039.736
Deduct 1866 from 1970 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
311 goes into 1040 3 times with a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 281039.7363
Subtracting 933 from 1040 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 13:
311 can be fit into 1070 3 times, resulting in a remainder of 137.
The next digit of our result is 3. 
Result so far: 281039.73633
Subtracting 933 from 1070 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

After the division, we end up with 281039.73633 and a remainder of 0.000137.
