We look at the division of 68393779 by 749 
Let's see how many times 749 fits into 68393779.

On to step 1:
When dividing 6 by 749, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 749

Advancing to step 2:
The number 749 fits into 68 0 times, leaving a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 749

On to step 3:
The number 749 fits into 683 0 times, leaving a remainder of 683.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 683 and we're left with 683.
Append the next digit (9) from the dividend to 683 and continue with: 6839 / 749

On to step 4:
749 goes into 6839 9 times with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 6741 from 6839, we get 98.
Include the next digit (3) from the dividend after 98, then repeat: 983 / 749

Moving on to step 5:
983 divided by 749 is 1 with a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we subtract 749 from 983, we get 234.
Append the next digit (7) from the dividend to 234 and continue with: 2347 / 749

Let's proceed to step 6:
2347 divided by 749 is 3 with a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 913.0
If we subtract 2247 from 2347, we get 100.
Fetch the next digit (7) from the dividend, attach it to 100 and continue: 1007 / 749

Advancing to step 7:
749 goes into 1007 1 times with a remainder of 258.
Record the quotient 1 as the next digit in the result. 
Result so far: 9131.0
If we take 749 away from 1007, we end up with 258.
Take the next digit (9) from the dividend and append it to 258, then repeat: 2589 / 749

Moving on to step 8:
749 can be fit into 2589 3 times, resulting in a remainder of 342.
Use 3 as the next digit of our solution. 
Result so far: 91313.0
If we subtract 2247 from 2589, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 9:
749 goes into 3420 4 times with a remainder of 424.
Record the quotient 4 as the next digit in the result. 
Result so far: 91313.4
If we subtract 2996 from 3420, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 10:
4240 divided by 749 is 5 with a remainder of 495.
Record the quotient 5 as the next digit in the result. 
Result so far: 91313.45
Deduct 3745 from 4240 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Step 11:
The number 749 fits into 4950 6 times, leaving a remainder of 456.
Put 6 as the next digit of the answer. 
Result so far: 91313.456
Subtracting 4494 from 4950 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 12:
The number 749 fits into 4560 6 times, leaving a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 91313.4566
The remainder is 66 after subtracting 4494 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 91313.4566, and the remainder is 0.00066.
