Let's divide 77378922 by 393
We want to divide 77378922 by 393.

Step 1:
393 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 393

On to step 2:
393 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 393

Going ahead to step 3:
The number 393 fits into 773 1 times, leaving a remainder of 380.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 393 from 773 and we're left with 380.
Grab the next digit (7) from the dividend, add it to 380, then carry on: 3807 / 393

Going ahead to step 4:
393 goes into 3807 9 times with a remainder of 270.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 3537 from 3807 leaves us with 270.
Include the next digit (8) from the dividend after 270, then repeat: 2708 / 393

Going ahead to step 5:
The number 393 fits into 2708 6 times, leaving a remainder of 350.
The next digit of our result is 6. 
Result so far: 196.0
If we subtract 2358 from 2708, we get 350.
Take the next digit (9) from the dividend and append it to 350, then repeat: 3509 / 393

Going ahead to step 6:
If we divide 3509 by 393, we get 8 and a remainder of 365.
Use 8 as the next digit of our solution. 
Result so far: 1968.0
Subtracting 3144 from 3509 leaves us with 365.
Take the next digit (2) from the dividend and append it to 365, then repeat: 3652 / 393

Going ahead to step 7:
When dividing 3652 by 393, we get 9 with a remainder of 115.
Write down 9 as next digit of the result. 
Result so far: 19689.0
Subtracting 3537 from 3652 leaves us with 115.
Take the next digit (2) from the dividend and append it to 115, then repeat: 1152 / 393

Going ahead to step 8:
When dividing 1152 by 393, we get 2 with a remainder of 366.
The next digit of our result is 2. 
Result so far: 196892.0
Subtract 786 from 1152 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 9:
393 can be fit into 3660 9 times, resulting in a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 196892.9
Deduct 3537 from 3660 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 10:
393 can be fit into 1230 3 times, resulting in a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 196892.93
If we subtract 1179 from 1230, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
The number 393 fits into 510 1 times, leaving a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 196892.931
If we take 393 away from 510, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 12:
393 can be fit into 1170 2 times, resulting in a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 196892.9312
If we take 786 away from 1170, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 13:
3840 divided by 393 is 9 with a remainder of 303.
Write down 9 as next digit of the result. 
Result so far: 196892.93129
If we take 3537 away from 3840, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 14:
If we divide 3030 by 393, we get 7 and a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 196892.931297
Deduct 2751 from 3030 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 15:
393 can be fit into 2790 7 times, resulting in a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 196892.9312977
Deduct 2751 from 2790 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 196892.9312977 with a remaining 3.9e-07.
