We look at the division of 77793551 by 591 
Let's see how many times 591 fits into 77793551.

Moving on to step 1:
When dividing 7 by 591, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 591

Let's proceed to step 2:
77 divided by 591 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 591

Advancing to step 3:
When dividing 777 by 591, we get 1 with a remainder of 186.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 591 from 777 leaves us with 186.
Bring next digit (9) of the dividend behind the 186 and repeat the process: 1869 / 591

On to step 4:
591 can be fit into 1869 3 times, resulting in a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1773 from 1869 leaves us with 96.
Append the next digit (3) from the dividend to 96 and continue with: 963 / 591

Advancing to step 5:
591 can be fit into 963 1 times, resulting in a remainder of 372.
The next digit of our result is 1. 
Result so far: 131.0
Subtracting 591 from 963 leaves us with 372.
Bring next digit (5) of the dividend behind the 372 and repeat the process: 3725 / 591

Advancing to step 6:
The number 591 fits into 3725 6 times, leaving a remainder of 179.
The next digit of our result is 6. 
Result so far: 1316.0
Deduct 3546 from 3725 and we're left with 179.
Bring next digit (5) of the dividend behind the 179 and repeat the process: 1795 / 591

Step 7:
If we divide 1795 by 591, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 13163.0
The remainder is 22 after subtracting 1773 from 1795.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 591

Advancing to step 8:
If we divide 221 by 591, we get 0 and a remainder of 221.
The number 0 becomes the next digit in our result. 
Result so far: 131630.0
Subtracting 0 from 221 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 9:
2210 divided by 591 is 3 with a remainder of 437.
Write down 3 as next digit of the result. 
Result so far: 131630.3
The remainder is 437 after subtracting 1773 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 10:
When dividing 4370 by 591, we get 7 with a remainder of 233.
Put 7 as the next digit of the answer. 
Result so far: 131630.37
Subtract 4137 from 4370 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 11:
591 goes into 2330 3 times with a remainder of 557.
The number 3 becomes the next digit in our result. 
Result so far: 131630.373
Subtracting 1773 from 2330 leaves us with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Moving on to step 12:
5570 divided by 591 is 9 with a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 131630.3739
If we subtract 5319 from 5570, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 13:
2510 divided by 591 is 4 with a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 131630.37394
Subtract 2364 from 2510 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 14:
591 goes into 1460 2 times with a remainder of 278.
The number 2 becomes the next digit in our result. 
Result so far: 131630.373942
Subtract 1182 from 1460 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 15:
2780 divided by 591 is 4 with a remainder of 416.
The next digit of our result is 4. 
Result so far: 131630.3739424
Subtract 2364 from 2780 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 16:
When dividing 4160 by 591, we get 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 131630.37394247
Deduct 4137 from 4160 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 131630.37394247, with a leftover of 2.3e-08.
