We're dividing 86787126 by 379 
Our goal is to divide 86787126 by 379.

On to step 1:
If we divide 8 by 379, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 379

Going ahead to step 2:
If we divide 86 by 379, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 379

Let's proceed to step 3:
If we divide 867 by 379, we get 2 and a remainder of 109.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 758 away from 867, we end up with 109.
Bring next digit (8) of the dividend behind the 109 and repeat the process: 1098 / 379

Moving on to step 4:
The number 379 fits into 1098 2 times, leaving a remainder of 340.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 758 from 1098 and we're left with 340.
Bring next digit (7) of the dividend behind the 340 and repeat the process: 3407 / 379

Moving on to step 5:
3407 divided by 379 is 8 with a remainder of 375.
Write down 8 as next digit of the result. 
Result so far: 228.0
If we subtract 3032 from 3407, we get 375.
Fetch the next digit (1) from the dividend, attach it to 375 and continue: 3751 / 379

On to step 6:
If we divide 3751 by 379, we get 9 and a remainder of 340.
Use 9 as the next digit of our solution. 
Result so far: 2289.0
Deduct 3411 from 3751 and we're left with 340.
Include the next digit (2) from the dividend after 340, then repeat: 3402 / 379

Let's proceed to step 7:
If we divide 3402 by 379, we get 8 and a remainder of 370.
Write down 8 as next digit of the result. 
Result so far: 22898.0
Deduct 3032 from 3402 and we're left with 370.
Append the next digit (6) from the dividend to 370 and continue with: 3706 / 379

Let's proceed to step 8:
3706 divided by 379 is 9 with a remainder of 295.
Write down 9 as next digit of the result. 
Result so far: 228989.0
If we take 3411 away from 3706, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 9:
If we divide 2950 by 379, we get 7 and a remainder of 297.
Write down 7 as next digit of the result. 
Result so far: 228989.7
If we subtract 2653 from 2950, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 10:
379 can be fit into 2970 7 times, resulting in a remainder of 317.
The next digit of our result is 7. 
Result so far: 228989.77
Deduct 2653 from 2970 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final outcome is 228989.77, with a leftover of 0.317.
