Let's divide 77386791 by 539
We're looking to find how many times 539 goes into 77386791.

Moving on to step 1:
539 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 539

Going ahead to step 2:
539 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 539

Let's proceed to step 3:
The number 539 fits into 773 1 times, leaving a remainder of 234.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 539 from 773, we get 234.
Grab the next digit (8) from the dividend, add it to 234, then carry on: 2348 / 539

Step 4:
When dividing 2348 by 539, we get 4 with a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 192 after subtracting 2156 from 2348.
Grab the next digit (6) from the dividend, add it to 192, then carry on: 1926 / 539

Let's proceed to step 5:
539 goes into 1926 3 times with a remainder of 309.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
If we take 1617 away from 1926, we end up with 309.
Append the next digit (7) from the dividend to 309 and continue with: 3097 / 539

Advancing to step 6:
539 goes into 3097 5 times with a remainder of 402.
Use 5 as the next digit of our solution. 
Result so far: 1435.0
If we subtract 2695 from 3097, we get 402.
Grab the next digit (9) from the dividend, add it to 402, then carry on: 4029 / 539

Going ahead to step 7:
539 can be fit into 4029 7 times, resulting in a remainder of 256.
The number 7 becomes the next digit in our result. 
Result so far: 14357.0
If we subtract 3773 from 4029, we get 256.
Take the next digit (1) from the dividend and append it to 256, then repeat: 2561 / 539

Moving on to step 8:
When dividing 2561 by 539, we get 4 with a remainder of 405.
Write down 4 as next digit of the result. 
Result so far: 143574.0
If we take 2156 away from 2561, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 9:
4050 divided by 539 is 7 with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 143574.7
Deduct 3773 from 4050 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 10:
539 can be fit into 2770 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 143574.75
Subtract 2695 from 2770 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
The number 539 fits into 750 1 times, leaving a remainder of 211.
The number 1 becomes the next digit in our result. 
Result so far: 143574.751
If we take 539 away from 750, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 12:
If we divide 2110 by 539, we get 3 and a remainder of 493.
The next digit of our result is 3. 
Result so far: 143574.7513
Subtract 1617 from 2110 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 13:
4930 divided by 539 is 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 143574.75139
The remainder is 79 after subtracting 4851 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 14:
539 goes into 790 1 times with a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 143574.751391
The remainder is 251 after subtracting 539 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 15:
If we divide 2510 by 539, we get 4 and a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 143574.7513914
The remainder is 354 after subtracting 2156 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 16:
If we divide 3540 by 539, we get 6 and a remainder of 306.
Write down 6 as next digit of the result. 
Result so far: 143574.75139146
Deduct 3234 from 3540 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final result is 143574.75139146 with a remainder of 3.06e-07.
