Let's divide 12031213 by 778
Our goal is to divide 12031213 by 778.

Going ahead to step 1:
The number 778 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 778

Moving on to step 2:
If we divide 12 by 778, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 778

Moving on to step 3:
If we divide 120 by 778, we get 0 and a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Append the next digit (3) from the dividend to 120 and continue with: 1203 / 778

Let's proceed to step 4:
778 can be fit into 1203 1 times, resulting in a remainder of 425.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 778 from 1203 and we're left with 425.
Include the next digit (1) from the dividend after 425, then repeat: 4251 / 778

Moving on to step 5:
778 can be fit into 4251 5 times, resulting in a remainder of 361.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 3890 from 4251 to get 361.
Include the next digit (2) from the dividend after 361, then repeat: 3612 / 778

Going ahead to step 6:
The number 778 fits into 3612 4 times, leaving a remainder of 500.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we subtract 3112 from 3612, we get 500.
Bring next digit (1) of the dividend behind the 500 and repeat the process: 5001 / 778

Advancing to step 7:
When dividing 5001 by 778, we get 6 with a remainder of 333.
Put 6 as the next digit of the answer. 
Result so far: 1546.0
Subtracting 4668 from 5001 leaves us with 333.
Append the next digit (3) from the dividend to 333 and continue with: 3333 / 778

Going ahead to step 8:
If we divide 3333 by 778, we get 4 and a remainder of 221.
The next digit of our result is 4. 
Result so far: 15464.0
If we take 3112 away from 3333, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 9:
The number 778 fits into 2210 2 times, leaving a remainder of 654.
Record the quotient 2 as the next digit in the result. 
Result so far: 15464.2
The remainder is 654 after subtracting 1556 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 10:
When dividing 6540 by 778, we get 8 with a remainder of 316.
Put 8 as the next digit of the answer. 
Result so far: 15464.28
Deduct 6224 from 6540 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 11:
The number 778 fits into 3160 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 15464.284
If we take 3112 away from 3160, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
If we divide 480 by 778, we get 0 and a remainder of 480.
The next digit of our result is 0. 
Result so far: 15464.284
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
778 can be fit into 4800 6 times, resulting in a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 15464.28406
The remainder is 132 after subtracting 4668 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 14:
If we divide 1320 by 778, we get 1 and a remainder of 542.
The number 1 becomes the next digit in our result. 
Result so far: 15464.284061
Subtract 778 from 1320 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 15:
5420 divided by 778 is 6 with a remainder of 752.
The number 6 becomes the next digit in our result. 
Result so far: 15464.2840616
Subtract 4668 from 5420 to get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 16:
The number 778 fits into 7520 9 times, leaving a remainder of 518.
Put 9 as the next digit of the answer. 
Result so far: 15464.28406169
Subtracting 7002 from 7520 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

The final result is 15464.28406169 with a remainder of 5.18e-07.
