We look at the division of 521039 by 768 
We're looking to find how many times 768 goes into 521039.

Step 1:
5 divided by 768 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 768

On to step 2:
If we divide 52 by 768, we get 0 and a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 768

Step 3:
768 can be fit into 521 0 times, resulting in a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 521, we get 521.
Grab the next digit (0) from the dividend, add it to 521, then carry on: 5210 / 768

Moving on to step 4:
When dividing 5210 by 768, we get 6 with a remainder of 602.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 602 after subtracting 4608 from 5210.
Grab the next digit (3) from the dividend, add it to 602, then carry on: 6023 / 768

Step 5:
When dividing 6023 by 768, we get 7 with a remainder of 647.
Write down 7 as next digit of the result. 
Result so far: 67.0
The remainder is 647 after subtracting 5376 from 6023.
Take the next digit (9) from the dividend and append it to 647, then repeat: 6479 / 768

Moving on to step 6:
When dividing 6479 by 768, we get 8 with a remainder of 335.
Put 8 as the next digit of the answer. 
Result so far: 678.0
Subtracting 6144 from 6479 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 7:
768 can be fit into 3350 4 times, resulting in a remainder of 278.
Put 4 as the next digit of the answer. 
Result so far: 678.4
Subtract 3072 from 3350 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 8:
768 can be fit into 2780 3 times, resulting in a remainder of 476.
Record the quotient 3 as the next digit in the result. 
Result so far: 678.43
The remainder is 476 after subtracting 2304 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 9:
768 goes into 4760 6 times with a remainder of 152.
The next digit of our result is 6. 
Result so far: 678.436
Deduct 4608 from 4760 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 10:
When dividing 1520 by 768, we get 1 with a remainder of 752.
The next digit of our result is 1. 
Result so far: 678.4361
If we subtract 768 from 1520, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

On to step 11:
If we divide 7520 by 768, we get 9 and a remainder of 608.
The number 9 becomes the next digit in our result. 
Result so far: 678.43619
Subtracting 6912 from 7520 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 12:
The number 768 fits into 6080 7 times, leaving a remainder of 704.
The number 7 becomes the next digit in our result. 
Result so far: 678.436197
Deduct 5376 from 6080 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 13:
768 can be fit into 7040 9 times, resulting in a remainder of 128.
Put 9 as the next digit of the answer. 
Result so far: 678.4361979
If we take 6912 away from 7040, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 14:
The number 768 fits into 1280 1 times, leaving a remainder of 512.
Record the quotient 1 as the next digit in the result. 
Result so far: 678.43619791
The remainder is 512 after subtracting 768 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Our division results in 678.43619791 with a remaining 5.12e-07.
