We look at the division of 863590 by 76 
We want to divide 863590 by 76.

On to step 1:
8 divided by 76 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 76

On to step 2:
76 can be fit into 86 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 76 from 86 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 76

Moving on to step 3:
If we divide 103 by 76, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 11.0
If we take 76 away from 103, we end up with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 76

Advancing to step 4:
275 divided by 76 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we subtract 228 from 275, we get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 76

Advancing to step 5:
76 goes into 479 6 times with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 1136.0
Subtracting 456 from 479 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 76

Step 6:
The number 76 fits into 230 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 11363.0
If we take 228 away from 230, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
76 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11363.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 76 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 11363.02
Subtract 152 from 200 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
76 goes into 480 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 11363.026
Subtract 456 from 480 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
If we divide 240 by 76, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 11363.0263
If we subtract 228 from 240, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
120 divided by 76 is 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 11363.02631
If we subtract 76 from 120, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
The number 76 fits into 440 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 11363.026315
The remainder is 60 after subtracting 380 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
76 can be fit into 600 7 times, resulting in a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 11363.0263157
The remainder is 68 after subtracting 532 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
When dividing 680 by 76, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 11363.02631578
The remainder is 72 after subtracting 608 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 11363.02631578, and the remainder is 7.2e-08.
