8879939 ÷ 393 
Our goal is to divide 8879939 by 393.

Going ahead to step 1:
The number 393 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 393

Let's proceed to step 2:
The number 393 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Include the next digit (7) from the dividend after 88, then repeat: 887 / 393

Let's proceed to step 3:
887 divided by 393 is 2 with a remainder of 101.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 786 from 887, we get 101.
Grab the next digit (9) from the dividend, add it to 101, then carry on: 1019 / 393

On to step 4:
1019 divided by 393 is 2 with a remainder of 233.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 786 from 1019 and we're left with 233.
Append the next digit (9) from the dividend to 233 and continue with: 2339 / 393

On to step 5:
The number 393 fits into 2339 5 times, leaving a remainder of 374.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
If we subtract 1965 from 2339, we get 374.
Bring next digit (3) of the dividend behind the 374 and repeat the process: 3743 / 393

Going ahead to step 6:
393 goes into 3743 9 times with a remainder of 206.
The next digit of our result is 9. 
Result so far: 2259.0
Subtracting 3537 from 3743 leaves us with 206.
Include the next digit (9) from the dividend after 206, then repeat: 2069 / 393

Step 7:
2069 divided by 393 is 5 with a remainder of 104.
The next digit of our result is 5. 
Result so far: 22595.0
Deduct 1965 from 2069 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.

Going ahead to step 8:
1040 divided by 393 is 2 with a remainder of 254.
The number 2 becomes the next digit in our result. 
Result so far: 22595.2
The remainder is 254 after subtracting 786 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 9:
When dividing 2540 by 393, we get 6 with a remainder of 182.
The number 6 becomes the next digit in our result. 
Result so far: 22595.26
The remainder is 182 after subtracting 2358 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 10:
When dividing 1820 by 393, we get 4 with a remainder of 248.
The next digit of our result is 4. 
Result so far: 22595.264
If we take 1572 away from 1820, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 11:
393 can be fit into 2480 6 times, resulting in a remainder of 122.
Put 6 as the next digit of the answer. 
Result so far: 22595.2646
Deduct 2358 from 2480 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 12:
When dividing 1220 by 393, we get 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 22595.26463
If we take 1179 away from 1220, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
If we divide 410 by 393, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 22595.264631
The remainder is 17 after subtracting 393 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
170 divided by 393 is 0 with a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 22595.264631
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
The number 393 fits into 1700 4 times, leaving a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 22595.26463104
Subtracting 1572 from 1700 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 22595.26463104 with a remainder of 1.28e-07.
