We're dividing 513912 by 68 
We want to divide 513912 by 68.

Moving on to step 1:
The number 68 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 68

Moving on to step 2:
The number 68 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 68

Moving on to step 3:
68 can be fit into 513 7 times, resulting in a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 476 from 513, we get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 68

Moving on to step 4:
68 goes into 379 5 times with a remainder of 39.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 340 from 379, we get 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 68

Let's proceed to step 5:
When dividing 391 by 68, we get 5 with a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 755.0
The remainder is 51 after subtracting 340 from 391.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 68

Going ahead to step 6:
The number 68 fits into 512 7 times, leaving a remainder of 36.
The next digit of our result is 7. 
Result so far: 7557.0
If we subtract 476 from 512, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
The number 68 fits into 360 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 7557.5
Subtracting 340 from 360 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 68, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 7557.52
Deduct 136 from 200 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 68, we get 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 7557.529
Subtracting 612 from 640 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
68 goes into 280 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 7557.5294
Deduct 272 from 280 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 68, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 7557.52941
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
68 can be fit into 120 1 times, resulting in a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 7557.529411
If we take 68 away from 120, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 7557.529411, with a leftover of 5.2e-06.
