75783519 ÷ 558 
We want to divide 75783519 by 558.

Step 1:
7 divided by 558 is 0 with 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.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 558

Step 2:
558 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 558

Going ahead to step 3:
757 divided by 558 is 1 with a remainder of 199.
The next digit of our result is 1. 
Result so far: 1.0
If we take 558 away from 757, we end up with 199.
Take the next digit (8) from the dividend and append it to 199, then repeat: 1998 / 558

On to step 4:
1998 divided by 558 is 3 with a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1674 from 1998 leaves us with 324.
Bring next digit (3) of the dividend behind the 324 and repeat the process: 3243 / 558

Advancing to step 5:
558 can be fit into 3243 5 times, resulting in a remainder of 453.
The next digit of our result is 5. 
Result so far: 135.0
Subtracting 2790 from 3243 leaves us with 453.
Take the next digit (5) from the dividend and append it to 453, then repeat: 4535 / 558

Going ahead to step 6:
558 can be fit into 4535 8 times, resulting in a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 1358.0
If we subtract 4464 from 4535, we get 71.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 558

Let's proceed to step 7:
If we divide 711 by 558, we get 1 and a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 13581.0
Subtracting 558 from 711 leaves us with 153.
Grab the next digit (9) from the dividend, add it to 153, then carry on: 1539 / 558

Moving on to step 8:
1539 divided by 558 is 2 with a remainder of 423.
Write down 2 as next digit of the result. 
Result so far: 135812.0
Subtracting 1116 from 1539 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 9:
If we divide 4230 by 558, we get 7 and a remainder of 324.
Put 7 as the next digit of the answer. 
Result so far: 135812.7
Subtracting 3906 from 4230 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 10:
The number 558 fits into 3240 5 times, leaving a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 135812.75
Deduct 2790 from 3240 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
558 goes into 4500 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 135812.758
Subtracting 4464 from 4500 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
558 goes into 360 0 times with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 135812.758
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 13:
3600 divided by 558 is 6 with a remainder of 252.
The next digit of our result is 6. 
Result so far: 135812.75806
Deduct 3348 from 3600 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 14:
558 goes into 2520 4 times with a remainder of 288.
The next digit of our result is 4. 
Result so far: 135812.758064
Subtracting 2232 from 2520 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 15:
If we divide 2880 by 558, we get 5 and a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 135812.7580645
Deduct 2790 from 2880 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 16:
If we divide 900 by 558, we get 1 and a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 135812.75806451
If we subtract 558 from 900, 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.

The final outcome is 135812.75806451, with a leftover of 3.42e-07.
