73279749 ÷ 578 
Our goal is to divide 73279749 by 578.

Let's proceed to step 1:
If we divide 7 by 578, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 578

On to step 2:
73 divided by 578 is 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 578

Advancing to step 3:
732 divided by 578 is 1 with a remainder of 154.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 154 after subtracting 578 from 732.
Fetch the next digit (7) from the dividend, attach it to 154 and continue: 1547 / 578

Going ahead to step 4:
1547 divided by 578 is 2 with a remainder of 391.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1156 from 1547 and we're left with 391.
Grab the next digit (9) from the dividend, add it to 391, then carry on: 3919 / 578

Going ahead to step 5:
3919 divided by 578 is 6 with a remainder of 451.
The next digit of our result is 6. 
Result so far: 126.0
If we take 3468 away from 3919, we end up with 451.
Bring next digit (7) of the dividend behind the 451 and repeat the process: 4517 / 578

Going ahead to step 6:
When dividing 4517 by 578, we get 7 with a remainder of 471.
Use 7 as the next digit of our solution. 
Result so far: 1267.0
If we subtract 4046 from 4517, we get 471.
Take the next digit (4) from the dividend and append it to 471, then repeat: 4714 / 578

Step 7:
578 goes into 4714 8 times with a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 12678.0
Subtract 4624 from 4714 to get 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 578

Going ahead to step 8:
578 goes into 909 1 times with a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 126781.0
Subtract 578 from 909 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 9:
578 goes into 3310 5 times with a remainder of 420.
Record the quotient 5 as the next digit in the result. 
Result so far: 126781.5
Subtracting 2890 from 3310 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
The number 578 fits into 4200 7 times, leaving a remainder of 154.
The number 7 becomes the next digit in our result. 
Result so far: 126781.57
Subtracting 4046 from 4200 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 11:
578 goes into 1540 2 times with a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 126781.572
The remainder is 384 after subtracting 1156 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
When dividing 3840 by 578, we get 6 with a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 126781.5726
Subtract 3468 from 3840 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 13:
578 can be fit into 3720 6 times, resulting in a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 126781.57266
The remainder is 252 after subtracting 3468 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Our division results in 126781.57266 with a remaining 0.000252.
