We're dividing 76122502 by 558 
Our goal is to divide 76122502 by 558.

Moving on to step 1:
558 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.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 558

Moving on to step 2:
When dividing 76 by 558, we get 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 558

Going ahead to step 3:
761 divided by 558 is 1 with a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 558 from 761, we get 203.
Append the next digit (2) from the dividend to 203 and continue with: 2032 / 558

Step 4:
When dividing 2032 by 558, we get 3 with a remainder of 358.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1674 from 2032 and we're left with 358.
Include the next digit (2) from the dividend after 358, then repeat: 3582 / 558

Let's proceed to step 5:
If we divide 3582 by 558, we get 6 and a remainder of 234.
The next digit of our result is 6. 
Result so far: 136.0
If we take 3348 away from 3582, we end up with 234.
Fetch the next digit (5) from the dividend, attach it to 234 and continue: 2345 / 558

Moving on to step 6:
558 goes into 2345 4 times with a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 1364.0
The remainder is 113 after subtracting 2232 from 2345.
Grab the next digit (0) from the dividend, add it to 113, then carry on: 1130 / 558

Let's proceed to step 7:
If we divide 1130 by 558, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 13642.0
If we subtract 1116 from 1130, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 558

Going ahead to step 8:
558 goes into 142 0 times with a remainder of 142.
Use 0 as the next digit of our solution. 
Result so far: 136420.0
Deduct 0 from 142 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 9:
If we divide 1420 by 558, we get 2 and a remainder of 304.
The next digit of our result is 2. 
Result so far: 136420.2
Deduct 1116 from 1420 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 10:
558 goes into 3040 5 times with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 136420.25
If we subtract 2790 from 3040, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 11:
When dividing 2500 by 558, we get 4 with a remainder of 268.
Write down 4 as next digit of the result. 
Result so far: 136420.254
Subtract 2232 from 2500 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 12:
The number 558 fits into 2680 4 times, leaving a remainder of 448.
Record the quotient 4 as the next digit in the result. 
Result so far: 136420.2544
The remainder is 448 after subtracting 2232 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 136420.2544, with a leftover of 0.00448.
