309878 ÷ 93 
Our goal is to divide 309878 by 93.

Going ahead to step 1:
93 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 93

On to step 2:
93 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 93

Step 3:
The number 93 fits into 309 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 279 from 309 to get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 93

Going ahead to step 4:
The number 93 fits into 308 3 times, leaving a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 279 away from 308, we end up with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 93

Let's proceed to step 5:
The number 93 fits into 297 3 times, leaving a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 333.0
Subtracting 279 from 297 leaves us with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 93

On to step 6:
The number 93 fits into 188 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 3332.0
If we subtract 186 from 188, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 93, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3332.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 93 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 3332.02
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
93 goes into 140 1 times with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 3332.021
Subtracting 93 from 140 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
If we divide 470 by 93, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 3332.0215
If we take 465 away from 470, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
93 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 3332.0215
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
93 can be fit into 500 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 3332.021505
If we subtract 465 from 500, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
If we divide 350 by 93, we get 3 and a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 3332.0215053
If we take 279 away from 350, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 14:
93 can be fit into 710 7 times, resulting in a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 3332.02150537
Subtracting 651 from 710 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final result is 3332.02150537 with a remainder of 5.9e-08.
