We look at the division of 86378806 by 757 
We want to divide 86378806 by 757.

Advancing to step 1:
When dividing 8 by 757, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 757

Moving on to step 2:
When dividing 86 by 757, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 757

Step 3:
863 divided by 757 is 1 with a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 757 away from 863, we end up with 106.
Include the next digit (7) from the dividend after 106, then repeat: 1067 / 757

Step 4:
757 can be fit into 1067 1 times, resulting in a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 757 away from 1067, we end up with 310.
Take the next digit (8) from the dividend and append it to 310, then repeat: 3108 / 757

Advancing to step 5:
If we divide 3108 by 757, we get 4 and a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we take 3028 away from 3108, we end up with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 757

Advancing to step 6:
When dividing 808 by 757, we get 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1141.0
If we subtract 757 from 808, we get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 757

Let's proceed to step 7:
The number 757 fits into 510 0 times, leaving a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 11410.0
Subtract 0 from 510 to get 510.
Grab the next digit (6) from the dividend, add it to 510, then carry on: 5106 / 757

Advancing to step 8:
5106 divided by 757 is 6 with a remainder of 564.
Put 6 as the next digit of the answer. 
Result so far: 114106.0
If we take 4542 away from 5106, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 9:
5640 divided by 757 is 7 with a remainder of 341.
Put 7 as the next digit of the answer. 
Result so far: 114106.7
Subtracting 5299 from 5640 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 10:
When dividing 3410 by 757, we get 4 with a remainder of 382.
Record the quotient 4 as the next digit in the result. 
Result so far: 114106.74
Subtract 3028 from 3410 to get 382.
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 11:
The number 757 fits into 3820 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 114106.745
If we subtract 3785 from 3820, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
757 goes into 350 0 times with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 114106.745
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 13:
757 goes into 3500 4 times with a remainder of 472.
Use 4 as the next digit of our solution. 
Result so far: 114106.74504
Subtract 3028 from 3500 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 14:
757 goes into 4720 6 times with a remainder of 178.
The number 6 becomes the next digit in our result. 
Result so far: 114106.745046
If we subtract 4542 from 4720, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 15:
1780 divided by 757 is 2 with a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 114106.7450462
If we subtract 1514 from 1780, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 16:
2660 divided by 757 is 3 with a remainder of 389.
The next digit of our result is 3. 
Result so far: 114106.74504623
Subtract 2271 from 2660 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

After the division, we end up with 114106.74504623 and a remainder of 3.89e-07.
