We look at the division of 78137811 by 374 
We want to divide 78137811 by 374.

Advancing to step 1:
7 divided by 374 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 374

Moving on to step 2:
If we divide 78 by 374, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 374

Going ahead to step 3:
The number 374 fits into 781 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 748 from 781 to get 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 374

Let's proceed to step 4:
The number 374 fits into 333 0 times, leaving a remainder of 333.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 333 after subtracting 0 from 333.
Fetch the next digit (7) from the dividend, attach it to 333 and continue: 3337 / 374

Step 5:
3337 divided by 374 is 8 with a remainder of 345.
Put 8 as the next digit of the answer. 
Result so far: 208.0
The remainder is 345 after subtracting 2992 from 3337.
Fetch the next digit (8) from the dividend, attach it to 345 and continue: 3458 / 374

Step 6:
When dividing 3458 by 374, we get 9 with a remainder of 92.
The next digit of our result is 9. 
Result so far: 2089.0
The remainder is 92 after subtracting 3366 from 3458.
Append the next digit (1) from the dividend to 92 and continue with: 921 / 374

Going ahead to step 7:
If we divide 921 by 374, we get 2 and a remainder of 173.
Use 2 as the next digit of our solution. 
Result so far: 20892.0
If we take 748 away from 921, we end up with 173.
Fetch the next digit (1) from the dividend, attach it to 173 and continue: 1731 / 374

Step 8:
The number 374 fits into 1731 4 times, leaving a remainder of 235.
The next digit of our result is 4. 
Result so far: 208924.0
If we take 1496 away from 1731, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
If we divide 2350 by 374, we get 6 and a remainder of 106.
Write down 6 as next digit of the result. 
Result so far: 208924.6
Deduct 2244 from 2350 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 10:
1060 divided by 374 is 2 with a remainder of 312.
Record the quotient 2 as the next digit in the result. 
Result so far: 208924.62
If we subtract 748 from 1060, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 11:
374 can be fit into 3120 8 times, resulting in a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 208924.628
Subtracting 2992 from 3120 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.

On to step 12:
1280 divided by 374 is 3 with a remainder of 158.
Use 3 as the next digit of our solution. 
Result so far: 208924.6283
If we subtract 1122 from 1280, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 13:
If we divide 1580 by 374, we get 4 and a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 208924.62834
If we take 1496 away from 1580, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
The number 374 fits into 840 2 times, leaving a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 208924.628342
Deduct 748 from 840 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 15:
If we divide 920 by 374, we get 2 and a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 208924.6283422
If we take 748 away from 920, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final result is 208924.6283422 with a remainder of 1.72e-06.
