We look at the division of 93878109 by 491 
Our goal is to divide 93878109 by 491.

Moving on to step 1:
491 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 491

Moving on to step 2:
If we divide 93 by 491, we get 0 and a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 93, we end up with 93.
Take the next digit (8) from the dividend and append it to 93, then repeat: 938 / 491

Going ahead to step 3:
When dividing 938 by 491, we get 1 with a remainder of 447.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 491 from 938, we get 447.
Bring next digit (7) of the dividend behind the 447 and repeat the process: 4477 / 491

Going ahead to step 4:
4477 divided by 491 is 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 4419 from 4477 and we're left with 58.
Append the next digit (8) from the dividend to 58 and continue with: 588 / 491

On to step 5:
The number 491 fits into 588 1 times, leaving a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 191.0
If we subtract 491 from 588, we get 97.
Fetch the next digit (1) from the dividend, attach it to 97 and continue: 971 / 491

Going ahead to step 6:
The number 491 fits into 971 1 times, leaving a remainder of 480.
The number 1 becomes the next digit in our result. 
Result so far: 1911.0
The remainder is 480 after subtracting 491 from 971.
Bring next digit (0) of the dividend behind the 480 and repeat the process: 4800 / 491

On to step 7:
The number 491 fits into 4800 9 times, leaving a remainder of 381.
The number 9 becomes the next digit in our result. 
Result so far: 19119.0
If we take 4419 away from 4800, we end up with 381.
Append the next digit (9) from the dividend to 381 and continue with: 3819 / 491

Advancing to step 8:
When dividing 3819 by 491, we get 7 with a remainder of 382.
The next digit of our result is 7. 
Result so far: 191197.0
The remainder is 382 after subtracting 3437 from 3819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 9:
The number 491 fits into 3820 7 times, leaving a remainder of 383.
Write down 7 as next digit of the result. 
Result so far: 191197.7
Subtract 3437 from 3820 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Let's proceed to step 10:
491 goes into 3830 7 times with a remainder of 393.
Use 7 as the next digit of our solution. 
Result so far: 191197.77
The remainder is 393 after subtracting 3437 from 3830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

In conclusion, the division gives 191197.77 with a balance of 0.393.
