Let's divide 77347979 by 542
We want to divide 77347979 by 542.

Step 1:
The number 542 fits into 7 0 times, leaving 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 (7) from the dividend to 7 and continue with: 77 / 542

Step 2:
If we divide 77 by 542, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 542

Step 3:
542 can be fit into 773 1 times, resulting in a remainder of 231.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 542 from 773 and we're left with 231.
Grab the next digit (4) from the dividend, add it to 231, then carry on: 2314 / 542

Moving on to step 4:
542 goes into 2314 4 times with a remainder of 146.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 146 after subtracting 2168 from 2314.
Include the next digit (7) from the dividend after 146, then repeat: 1467 / 542

Step 5:
542 can be fit into 1467 2 times, resulting in a remainder of 383.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
Subtract 1084 from 1467 to get 383.
Append the next digit (9) from the dividend to 383 and continue with: 3839 / 542

On to step 6:
542 goes into 3839 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 1427.0
Subtract 3794 from 3839 to get 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 542

Let's proceed to step 7:
457 divided by 542 is 0 with a remainder of 457.
Use 0 as the next digit of our solution. 
Result so far: 14270.0
Subtracting 0 from 457 leaves us with 457.
Bring next digit (9) of the dividend behind the 457 and repeat the process: 4579 / 542

Advancing to step 8:
542 goes into 4579 8 times with a remainder of 243.
Put 8 as the next digit of the answer. 
Result so far: 142708.0
Deduct 4336 from 4579 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 9:
2430 divided by 542 is 4 with a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 142708.4
The remainder is 262 after subtracting 2168 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 10:
2620 divided by 542 is 4 with a remainder of 452.
Put 4 as the next digit of the answer. 
Result so far: 142708.44
If we take 2168 away from 2620, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final result is 142708.44 with a remainder of 0.452.
