Let's divide 3818123 by 78
Let's see how many times 78 fits into 3818123.

Step 1:
3 divided by 78 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 78

On to step 2:
The number 78 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 78

Going ahead to step 3:
78 can be fit into 381 4 times, resulting in a remainder of 69.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 312 from 381 to get 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 78

Step 4:
If we divide 698 by 78, we get 8 and a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 74 after subtracting 624 from 698.
Append the next digit (1) from the dividend to 74 and continue with: 741 / 78

On to step 5:
741 divided by 78 is 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 489.0
The remainder is 39 after subtracting 702 from 741.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 78

Advancing to step 6:
The number 78 fits into 392 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 4895.0
If we take 390 away from 392, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 78

Going ahead to step 7:
The number 78 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 48950.0
Deduct 0 from 23 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
When dividing 230 by 78, we get 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 48950.2
Deduct 156 from 230 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 48950.29
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
If we divide 380 by 78, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 48950.294
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
680 divided by 78 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 48950.2948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
When dividing 560 by 78, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 48950.29487
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
140 divided by 78 is 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 48950.294871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
When dividing 620 by 78, we get 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 48950.2948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 15:
If we divide 740 by 78, we get 9 and a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 48950.29487179
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 48950.29487179 with a remainder of 3.8e-08.
