We look at the division of 86378086 by 379 
We want to divide 86378086 by 379.

Let's proceed to step 1:
8 divided by 379 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 379

Going ahead to step 2:
The number 379 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 379

Step 3:
379 goes into 863 2 times with a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 758 from 863, we get 105.
Fetch the next digit (7) from the dividend, attach it to 105 and continue: 1057 / 379

Advancing to step 4:
379 goes into 1057 2 times with a remainder of 299.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 299 after subtracting 758 from 1057.
Take the next digit (8) from the dividend and append it to 299, then repeat: 2998 / 379

Advancing to step 5:
379 goes into 2998 7 times with a remainder of 345.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
Subtract 2653 from 2998 to get 345.
Append the next digit (0) from the dividend to 345 and continue with: 3450 / 379

On to step 6:
3450 divided by 379 is 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 2279.0
Subtracting 3411 from 3450 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 379

Let's proceed to step 7:
When dividing 398 by 379, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 22791.0
Deduct 379 from 398 and we're left with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 379

Going ahead to step 8:
196 divided by 379 is 0 with a remainder of 196.
Write down 0 as next digit of the result. 
Result so far: 227910.0
Subtracting 0 from 196 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 9:
1960 divided by 379 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 227910.5
The remainder is 65 after subtracting 1895 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 10:
If we divide 650 by 379, we get 1 and a remainder of 271.
The next digit of our result is 1. 
Result so far: 227910.51
Subtracting 379 from 650 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 11:
2710 divided by 379 is 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 227910.517
Deduct 2653 from 2710 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
If we divide 570 by 379, we get 1 and a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 227910.5171
Subtract 379 from 570 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 13:
When dividing 1910 by 379, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 227910.51715
Subtract 1895 from 1910 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
The number 379 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 227910.51715
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
379 can be fit into 1500 3 times, resulting in a remainder of 363.
The number 3 becomes the next digit in our result. 
Result so far: 227910.5171503
If we take 1137 away from 1500, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Moving on to step 16:
379 can be fit into 3630 9 times, resulting in a remainder of 219.
Use 9 as the next digit of our solution. 
Result so far: 227910.51715039
Deduct 3411 from 3630 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

After the division, we end up with 227910.51715039 and a remainder of 2.19e-07.
