511431 divided by 68 
We're looking to find how many times 68 goes into 511431.

Let's proceed to step 1:
If we divide 5 by 68, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 68

Step 2:
The number 68 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 68

Going ahead to step 3:
68 goes into 511 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 476 from 511 and we're left with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 68

On to step 4:
If we divide 354 by 68, we get 5 and a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 340 from 354, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 68

Step 5:
When dividing 143 by 68, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 752.0
If we take 136 away from 143, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 68

Moving on to step 6:
68 goes into 71 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7521.0
Subtracting 68 from 71 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 68, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7521.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 68 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 7521.04
Subtract 272 from 300 to get 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 9:
The number 68 fits into 280 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 7521.044
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 7521.044, and the remainder is 0.0008.
